When the acceptance problem or the acceptance task is generated, the platform automatically performs automatic drawing mode configuration verification, channel message consistency analysis and acceptance responsibility area inspection on the monitoring information table of the acceptance substation, and the time for analyzing and positioning the acceptance problem and the problem reason is reduced.

Further, in the aspect of network communication, before the platform is accepted, substation personnel need to generate tasks on the platform and perform acceptance task environment verification in advance, wherein the problems that the names of common substation monitoring signals are wrong, the time of the substation monitoring signals is asynchronous with I, III zones and the like can be found and solved before the acceptance tasks are generated.

Furthermore, when there is a delay problem in the time of the signal sent from the substation equipment to reach the master station, a certain joint debugging acceptance time window is considered to be set, and acceptance can be qualified as long as the signal without strict sequence requirement is sent within the window range. And under the condition of strictly requiring the signal group to arrive in sequence to be checked and accepted, strictly executing the sequence arrival requirement, and requiring the platform to repeatedly check and accept on site.

A joint debugging method of an intelligent joint debugging platform of a transformer substation and a main station comprises the following steps:

Furthermore, the power grid equipment is accessed to the master station for centralized monitoring, and the required monitoring information joint debugging and acceptance check work refers to the checking and acceptance check of the correctness and consistency of the three remote signals including equipment remote signaling, remote monitoring and remote control accessed to the master station monitoring system. The checking of the remote signaling signals is to transmit action signals triggered by the primary and secondary equipment of the transformer substation to the master station, and then to check the consistency and the action correctness of the action signals with a remote signaling definition table in the master station system. Checking whether the names and the configurations defined by the transmitted signals and the monitoring information of the main station are consistent and standard, and judging whether the signals appear in sequence, accompanying signals exist or not;

the remote measuring signal is checked by adding the current and the voltage of the equipment on site through a transformer substation, the corresponding remote measuring value is uploaded to a master station, and the master station personnel judge whether the received remote measuring value is in a reasonable and correct interval according to a set range. Remote control acceptance is that a master station worker initiates an instruction, and a substation worker checks whether the action and the state of the equipment are correct on site.

Furthermore, the collection, arrangement and monitoring information checking and accepting process generates various problems, and an auxiliary diagnosis model method for automatically diagnosing conventional problems and providing treatment experience is designed. According to the diagnosis method model, an auxiliary diagnosis software function module is developed to assist the monitoring signal to be accessed to the master station for checking and accepting, so that the capability of personnel for checking and solving problems on site is improved;

Detailed Description

At present, the red river power supply bureau dispatching master station system realizes integrated intensive management of regulation and control of a main distribution network region and county, and the total regulation and control is reduced by more than 40%, so that the demand for load reduction and efficiency improvement of existing personnel is very urgent.

In the aspect of joint debugging and acceptance of the monitoring information of the main and distribution network equipment accessing to the main station monitoring system, the power grid equipment of the power supply office of the red river accessing to the main station is monitored in a centralized manner, and monitoring information joint debugging and acceptance are needed, namely, substation personnel trigger equipment signals one by one on site and add analog quantities such as current and voltage, and the main station personnel check whether the monitoring system responses correctly and then call back results. In the whole process, master station scheduling personnel need to wait for coordination for a long time, and professional manual diagnosis is needed when problems occur.

The following disadvantages mainly exist:

1. the special person at the master station end needs to be dispatched to cooperate with checking, so that time and labor are wasted. Operation and maintenance need apply for scheduling mechanism allotment personnel cooperation debugging, and many problems of check in-process need the manual work to carry out professional analysis, wait for a long time, in case the time limit for a project is nervous, a plurality of websites are qualified for the next round of competitions simultaneously, lead to main website personnel work full load.

2. The monitoring information is checked manually, and mistakes and omissions are easily generated. In the actual acceptance check, a plurality of intervals or batches are accompanied by signals, and the error and leakage phenomenon is easily caused by manual acceptance check.

3. The construction period is easily delayed by depending on the cooperation of the main station. Because the self-checking means is lacked before the checking and accepting link, operation and maintenance personnel easily delay the work of checking and accepting the treatment on site in the early stage to the monitoring information access joint debugging and accepting link in the later stage, so that the checking and accepting progress is tense, and the overall construction period is delayed.

4. The monitoring information checking and accepting process is lack of detailed records and strict. The existing signal access monitoring information checking acceptance report lacks checking acceptance signal record, and a signal one-by-one hooking mode is adopted, so that the checking acceptance work is inconvenient to trace and guarantee.

5. When the information is monitored and the information correctness is checked, the correct response of the automatic main station terminal light word plate information is checked, omission easily occurs, repeated processes also occur in the checking process, the time is wasted, and the overall efficiency and the checking quality are reduced.

Therefore, advanced technical means are urgently needed to be adopted, work burden reduction, quality improvement and efficiency improvement are carried out on main station personnel, the main station personnel do not need to be matched for a long time, on-site operation and maintenance personnel at the transformer station end can automatically find and utilize a computer to automatically check and accept, the error cause of check and acceptance can be quickly known, a detailed check and acceptance record report is given, and finally joint debugging and check and acceptance of the transformer station monitoring information access main station can be completed at one time.

The invention will be further described with reference to the following figures and examples.

At present, the process of connecting the power grid monitoring signals to the master station and debugging and accepting at home and abroad mainly adopts manual debugging and accepting, namely, signals are manually sent on site, and then master station personnel check whether the signal action is accurate from the monitoring system and feed the result back to the site operation and maintenance. Due to the fact that the combined debugging process exists, careless omission often occurs in the initial stage of on-site acceptance check of operation and maintenance, most of problems found in the final combined debugging process of the transformer substation are on-site problems, and master station personnel have to wait for problem repair and then continue acceptance check, so that on one hand, work is delayed, and on the other hand, the operation period of the transformer substation is delayed. In addition, because the project construction is delayed during the summer period of the peak-to-peak degree, and after summer, the phenomenon of centralized joint debugging of a large number of transformer substation construction, transformation and extension projects sometimes occurs, in order to check and accept work, a dispatcher often needs to deal with the check and accept of a plurality of projects, the workload of the dispatcher is increased, and errors are easy to occur.

Therefore, efficiency improvement is carried out by some units, for example, a national grid Zhenjiang power supply company carries out innovation from management, aiming at the problems that the time of a joint acceptance process is long, careless omission easily occurs in the value of a plurality of turns and the like, a management system special for acceptance of a newly-built transformer substation, namely an acceptance group system is established, all participants are intensively responsible for acceptance work in a group, and improvement is carried out on an acceptance method and implementation details, so that the problem that careless omission easily occurs in the joint acceptance of the value of the plurality of turns can be solved to a certain extent, but the problem that the matching joint adjustment time of master station personnel is too long cannot be solved, and the problem that the efficiency of each party in the joint adjustment is not completely changed on the whole. The state network and cloud port power supply company uses 8 portable simulation scheduling master stations to perform off-line debugging of the newly-built transformer substation, only signal sampling inspection verification work is needed between the newly-built transformer substation and the scheduling master station after a formal channel is provided, and online joint debugging time of the main transformer substation is greatly shortened; in addition, the soft signal terminal row technology based on the message replay principle is provided to realize repeated simulation of soft message signals, and the test efficiency of the telecontrol protocol information point table between the transformer substation and the plurality of dispatching masters is improved. The device has the advantages that the rapid acceptance of the master station end to the monitoring signals can be realized, the responsibility of sectional acceptance is clear, and the defects that at present, the SCD file formats of all comprehensive manufacturers are different in definition, and the SCD files are difficult to directly import into the device, so that the files such as the SCD of the transformer station end need to be repeatedly manufactured at the initial stage of acceptance, the file manufacturing is time-consuming and labor-consuming, and once errors occur, hidden dangers are easily caused.

The invention is based on the research of providing the on-site operation and maintenance self-service joint debugging acceptance before the monitoring signal is accessed into the master station system and the problem auxiliary diagnosis technology, the computer is used for automatically judging the acceptance result and assisting in diagnosing the acceptance defect, the joint debugging network and the hardware environment are consistent with the manual joint debugging acceptance, the popularization is easy, the one-time pass rate of joint debugging is improved, and the time for matching the master station with the joint debugging acceptance is saved.

2. Introduces the past research situation and the existing technical bottleneck of the south power grid company for solving the problem of the project.

The power grid equipment monitoring signal acceptance work mainly comprises the joint debugging acceptance of the transformer station end signal acceptance and the transformer station access master station monitoring system, the existing research of southern power grid companies is mainly in the field signal acceptance of the transformer station end, for example, the Foshan power supply bureau of Guangdong power grid Limited liability company proposes a method for verifying secondary equipment (such as protection, measurement and control, network analyzer, intelligent electric meter and the like), a secondary loop and an acquisition device in an intelligent transformer station by using small signals, the occurrence of high voltage in the test can be avoided, the safety of the test environment is guaranteed, and the secondary equipment and the secondary loop can be completely verified. The Liuzhou office of the ultra-high voltage transmission company provides a development scheme of intelligent detection software for a secondary virtual circuit of a transformer substation according to the characteristics of a digital transformer substation. The detection software takes an SCD file configured by a digital substation total station as a detection basis, firstly, virtual terminal connections in the SCD are led out at intervals, information associated with each interval is generated into a file in a table form, whether association logic meets the requirement of substation design is checked, and static detection is carried out; and secondly, performing communication working condition, message analysis and simulation transceiving detection on the network communication, verifying whether the communication behavior of the equipment meets the IEC 61850 standard and engineering design requirements or not according to the information configured in the SCD, and performing dynamic detection. The software used as an auxiliary debugging tool of the digital transformer substation can replace a universal meter used in the debugging of a conventional transformer substation, help is provided for the debugging and acceptance of engineering, and convenience is provided for finding problems occurring in operation as soon as possible. Meanwhile, a power grid company also obtains a plurality of acceptance criteria and combined debugging acceptance experience summaries, such as relay protection and relevant secondary circuit acceptance criteria, and the like, and a power grid limited responsibility company Guiyang power supply office carries out acceptance experience summaries in the aspects of equipment quality, factory debugging, interference resistance of an electronic transformer, construction of optical cables and optical fibers, monitoring of network messages and the like; some cautions in the acceptance are summarized by the first power supply bureau of the Guangdong power grid Limited company, the importance of information checking in the acceptance is particularly provided, and the phenomena of negligence and omission in the manual acceptance process are prevented.

Therefore, currently, the main research work of southern power grid companies is to solve some common problems in substation field acceptance and check and standardize by using tools, so as to reduce the number of problems in later-stage joint debugging acceptance and check. In the later stage of checking and accepting the transformer substation monitoring signal access master station system, the transformer substation and the master station are still required to be manually jointly adjusted and checked and accepted by both sides, an automatic and intelligent scheme adopted by a document is not yet seen, and the problems that the complex, low-efficiency and accuracy of manual judgment of signal correctness and the like are difficult to guarantee due to the fact that dispatching personnel at the end of the joint adjustment checking and accepting master station need to cooperate with a transformer substation field are solved.

As shown in fig. 1 and 2, the transformer substation and master station intelligent joint debugging platform includes:

The transformer substation and main station intelligent joint debugging platform is built on a main station side three-area server (monitoring information intelligent joint debugging acceptance server), monitoring information checking personnel on the transformer substation side accesses a Web management interface of the monitoring information intelligent joint debugging acceptance server through an acceptance terminal PC in three areas, enters a corresponding acceptance task and selects a signal needing acceptance, remote signaling of equipment is triggered on site or the addition of a remote measurement value is triggered on site, and the signal is sent to a main station front-end processor and a dispatching automation platform database through an area channel. The dispatching automation platform uploads a three-remote signal definition table, a received equipment remote signal action signal and a remote measuring value to the transverse isolation device in real time through a signal action interface, and the three-region monitoring information intelligent checking server reads action signal data on the transverse isolation device, automatically checks according to a checking model and completes joint dispatching and checking of the signal. When the acceptance problem or the acceptance task is generated, the platform automatically performs automatic drawing mode configuration verification, channel message consistency analysis and acceptance responsibility area inspection on the monitoring information table of the acceptance substation, and the time for analyzing and positioning the acceptance problem and the problem reason is reduced.

In the aspect of network communication, before the platform is accepted, substation personnel need to generate tasks on the platform and execute the environmental verification of the acceptance tasks in advance, wherein the problems that the names of common substation monitoring signals are wrong, the time of the substation monitoring signals is asynchronous with I, III zones and the like can be found and solved before the acceptance tasks are generated.

When there is a delay problem in the time of the signal sent from the substation equipment to reach the master station, a certain joint debugging acceptance time window is considered to be set (the traditional manual joint debugging acceptance is basically solved by adopting the mode when the problems are met), and the acceptance can be qualified as long as the signal without strict sequence requirements is sent within the window range. And under the condition of strictly requiring the signal group to arrive in sequence to be checked and accepted, strictly executing the sequence arrival requirement, and requiring the platform to repeatedly check and accept on site.

the method comprises the steps that the existing substation equipment monitoring information is arranged and accessed to a master station, a dispatcher at the master station end manually checks rules, and multi-signal sequence and whole group monitoring information checking model research in the equipment monitoring information checking and accepting process is mainly carried out; a new power grid equipment centralized monitoring information checking scheme is set, the less-duty and on-site self-service acceptance of a master station is realized, a rule base is mainly established, and computer software is utilized to filter, automatically judge and feedback and display equipment action signals in a dispatching automation system, so that the function of quickly accepting the power grid equipment centralized monitoring information signals is realized, and the precision and the efficiency of on-site acceptance are improved.

The joint debugging method of the intelligent joint debugging platform of the transformer substation and the main station further comprises the following steps:

collecting and sorting various problems generated in the joint debugging acceptance of the monitoring information of the transformer substation, and designing an automatic diagnosis and auxiliary diagnosis model method for conventional problems (such as wiring errors, inconsistency between a site and a master station information table, errors in a signal responsibility area, inconsistency of channel messages and the like); and according to the diagnosis method model, an auxiliary diagnosis software core function module is arranged, and an auxiliary monitoring signal is accessed to the master station to jointly debug and accept, so that the capability of on-site personnel to accept and solve problems is improved.

The power grid equipment is accessed to the master station for centralized monitoring, and the required monitoring information joint debugging and acceptance check work refers to the checking and acceptance check of the correctness and consistency of the three remote signals including equipment remote signaling, remote monitoring and remote control accessed to the master station monitoring system. The checking of the remote signaling signals is to transmit action signals triggered by the primary and secondary equipment of the transformer substation to the master station, and then to check the consistency and the action correctness of the action signals with a remote signaling definition table in the master station system. Checking whether the names and the configurations defined by the transmitted signals and the monitoring information of the main station are consistent and standard, and judging whether the signals appear in sequence, accompanying signals exist or not; for checking a single signal, for example, when the signal "110 kV buscouple 710 switch protection measurement and control device SV data is abnormal", it is directly judged whether the name of the action signal is correct, that is, whether the signal appears, and when checking and accepting the "XX line reclosing exit", the signal action needs to be returned once. For checking and acceptance of a plurality of associated signals, for example, when the reference signal "XX line protection measurement and control device alarm" is checked and accepted, the combination relationship of the associated signals needs to be checked as shown in the following table 1, and the check and acceptance is passed after the associated signals appear:

TABLE 1

Remote signalling name	Serial number
		XX line protection measurement and control device alarm	1
XX line protection TV broken wire	2
		XX switch	3

The remote measuring signal is checked by adding the current and the voltage of the equipment on site through a transformer substation, the corresponding remote measuring value is uploaded to a master station, and the master station personnel judge whether the received remote measuring value is in a reasonable and correct interval according to a set range. Remote control acceptance is that a master station worker initiates an instruction, and a substation worker checks whether the action and the state of the equipment are correct on site. In the actual acceptance process, the occupation ratio of the remote control signal quantity is very limited, and the acceptance problem is less. The number of remote signaling and remote measuring accounts for more than 90%, the acceptance problems are high, and the occupied time is long. The main station cooperates with the checking and accepting personnel to work, and the essence of the method is that based on a certain strategy, the consistency comparison and judgment process of the change signals and the signal definitions received in the monitoring system of the main station are repeated for many times.

The method comprises the steps of collecting, sorting and monitoring information, checking and accepting various problems generated in the process, designing an auxiliary diagnosis model method for automatically diagnosing conventional problems (such as wiring errors, inconsistency between a site and a master station information table, errors in signal responsibility areas, inconsistency of channel messages and the like) and providing treatment experience. According to the diagnosis method model, an auxiliary diagnosis software function module is developed to assist the monitoring signal to be accessed to the master station for checking and accepting, so that the capability of personnel for checking and solving problems on site is improved;

On the basis of the power grid equipment monitoring information checking and accepting model, monitoring information joint debugging and accepting background management software is arranged, the whole monitoring information joint debugging and accepting process management and control are achieved, and the functions of task scheduling, monitoring information accepting preparation, monitoring information fast checking and accepting, acceptance defect intelligent diagnosis, acceptance report generation, acceptance evaluation and the like are achieved. Meanwhile, certain evaluation standards are formulated for the links of design, audit, access, debugging, acceptance check and the like in the process of acceptance check, quantitative evaluation is carried out, and the quality of monitoring information checking and acceptance check work is improved.

General objects of the invention: the difficulty and the load of the master station dispatcher for matching acceptance are reduced by advanced technical means, and the following aims can be achieved: (1) signals of more than 90% of three-remote monitoring information of the transformer substation do not need to be matched with master station personnel, and the correctness of the operation and maintenance personnel of the transformer substation can be automatically and quickly verified. (2) The on-site operation and maintenance personnel of the transformer substation can diagnose the acceptance problems in time and shorten the acceptance time.

The social benefits of the invention are as follows:

(1) the time for checking and accepting by the dispatching personnel of the master station in cooperation with the monitoring information of the transformer substation is saved, and the economic expenditure is saved by 10.8 ten thousand yuan each year.

At present, a power grid device monitoring signal is accessed to a master station system monitoring information checking and accepting field, the master station needs to be manually matched with the current project implementation (key technology research) field, signal checking is carried out by means of manual experience, and due to the fact that substation devices often avoid concentrated operation in power utilization seasons, combined debugging time is urgent, manual matching monitoring information checking and accepting is overwhelmed, and errors are inevitable. After the system is used, the workload of checking and accepting the monitoring information in manual cooperation is reduced. Generally, the checking and accepting time for checking the monitoring information is 5 days for every 1000 monitoring signals on average, and after the platform is adopted, the workload of the master station and staff can be reduced to 0.5 day. According to the calculation, the checking and acceptance of the monitoring information are calculated by 4 ten thousand information points every year, 40 thousand times 4.5 days/thousand times 180 days can be saved, and according to the calculation of 600 yuan per day, 180 days times 600 yuan/day times 10.8 ten thousand yuan can be saved every year.

(2) Is favorable for improving the working efficiency of personnel.

After the project achievement is put into use, the field operation and maintenance personnel can see the change condition of the signal when the signal is checked and accepted by the signal access master station system, the signal is not needed to be analyzed and judged to be accepted manually, the acceptance problem is met, the problem generation reason can be directly known, the coordination and the quick solution are realized, the coordination, coordination and interaction cost of the master station personnel are reduced, and the working efficiency of the personnel is improved.

The invention has the following technical effects:

(1) the arrangement difficulty of the power failure plan can be reduced, and the power failure duration and the power failure times can be reduced.

Before the platform is put into operation, when a plurality of project centralized monitoring information joint debugging acceptance or individual project monitoring information joint debugging acceptance is delayed, due to the need of coordinating limited working staff of the master station, the power failure plan is often required to be rearranged, and the total power failure duration is increased. After the system is put into operation, the master station can support parallel joint debugging acceptance of a plurality of engineering projects, and is favorable for reducing the power failure duration and the power failure times to a certain extent.

(2) The safe and stable operation of the transformer substation is promoted.

The monitoring signal access master station system monitoring information joint debugging acceptance in the traditional mode depends on manual judgment, the record of an acceptance report is incomplete, the guarantee coefficient needs to be improved, and many names and configuration errors are discovered in later operation. The invention utilizes the computer rule to study and judge, replaces manual work, can record the acceptance process and form a detailed and accurate acceptance report, and is more reliable compared with the traditional manual joint debugging acceptance report, thereby being beneficial to improving the safe and stable operation of the transformer substation.

In conclusion, the application value of the invention is obvious.

The present invention has been described above in an illustrative manner by way of embodiments, and it will be understood by those skilled in the art that the present disclosure is not limited to the embodiments described above, and various changes, modifications and substitutions can be made without departing from the scope of the present invention.
