背景技术Background technique
随着配电网的数字化、信息化、自动化、互动化和智能化的发展，对配电终端的遥控、遥测、遥信“三遥”信息的标准化、配电终端调试的效率的要求越来越高。目前终端与实际运行主站之间通信设备的铺设需要很长时间，给配电终端的调试带来很大的不利。目前在进行配电自动化就地调试时，需要与主站保持通信，在现场需要由终端调试人员，还需一人在实际运行主站进行配合，在通信设施等出现故障时，便会无法与主站取得联系，导致现场调试无法正常进行，造成人员和时间的极大浪费。With the development of digitalization, informatization, automation, interaction and intelligence of the distribution network, there are more and more requirements for the standardization of remote control, telemetry and remote signaling "three remote" information of distribution terminals and the efficiency of distribution terminal debugging. higher. At present, the laying of communication equipment between the terminal and the actual operating master station takes a long time, which brings great disadvantages to the commissioning of the power distribution terminal. At present, in the on-site debugging of power distribution automation, it is necessary to maintain communication with the main station. On-site commissioning personnel are required, and one person is required to cooperate with the actual operation of the main station. When the communication facilities fail, it will not be able to communicate with the main station The station got in touch, resulting in the failure of on-site commissioning, resulting in a great waste of personnel and time.
(1)配电终端上送的数据要有明确的含义，不同终端设备厂商制定一个统一的标准点表模版及自动生成方法；(1) The data sent by the power distribution terminal must have a clear meaning, and different terminal equipment manufacturers formulate a unified standard point table template and automatic generation method;
(2)配电终端设备需要具备自描述功能及统一的接口规范；(2) Power distribution terminal equipment needs to have self-describing functions and unified interface specifications;
(3)有效配电自动化快速接入与联调、验收方法，保障配电系统的实用化；(3) Effective fast access, joint commissioning, and acceptance methods of power distribution automation to ensure the practicality of power distribution systems;
(4)标准的终端设备现场调试流程，自动生成终端调试报告，能够及时准确排除现场故障；(4) The standard on-site debugging process of terminal equipment can automatically generate a terminal debugging report, which can timely and accurately troubleshoot on-site faults;
(5)达到安全性，可靠性，稳定性的要求。(5) Meet the requirements of safety, reliability and stability.
在传统的配电自动化就地调试中，配电终端(环网柜DTU、柱上开关FTU等)信息的规范接入配电主站需要终端侧人员人工进行三遥点表信号的甄别与提交，再通过主站维护人员与终端调试人员提供的信息进行逐点对试校核。配电终端与配电主站之间的传动试验依靠人工完成、终端与主站远距离调试工作效率低，现场基础调试对通信依赖性大，不利于配电自动化系统的大规模建设和推广应用。依靠人工方式传递遥信、遥测、遥控点表，然后主站手动将信息点表输入数据库的方式存在数据含义不明确和各种数据之间关联性不强的问题。目前配电端接入联调受通信等外在环境制约、联调工作量大、现场需要停电时间长等难题。In the traditional on-site commissioning of power distribution automation, the specification of information on power distribution terminals (ring main unit DTU, pole-mounted switch FTU, etc.) is connected to the main power distribution station, and personnel on the terminal side need to manually identify and submit the signals of the three remote point meters. , and then conduct a point-by-point test check through the information provided by the main station maintenance personnel and the terminal debugging personnel. The transmission test between the power distribution terminal and the main power distribution station is completed manually, the remote debugging work between the terminal and the main station is inefficient, and the on-site basic debugging is highly dependent on communication, which is not conducive to the large-scale construction and popularization and application of the power distribution automation system . Relying on manual transmission of remote signaling, telemetry, remote control point table, and then the master station manually enters the information point table into the database, there are problems of unclear data meaning and weak correlation between various data. At present, the joint commissioning of the power distribution terminal is restricted by the external environment such as communication, the workload of the joint commissioning is large, and the on-site power outage time is long.
本发明通过设计一种可存放于笔记本电脑的模拟主站，便于调试人员随身携带，在进行配电自动化就地调试时，不需终端与实际运行主站的通信设备铺设完备，便可进行全过程自动化调试，降低目前实际运行主站面临的多个终端同时接入的协调难度，根据现场调试情况，自动生成可阅调试报告，提高调试效率。The present invention designs a simulated master station that can be stored in a notebook computer, which is convenient for debugging personnel to carry around. When performing on-site debugging of power distribution automation, the complete communication equipment between the terminal and the actual running master station is not required. The process automation debugging reduces the coordination difficulty of simultaneous access of multiple terminals faced by the actual running master station. According to the on-site debugging situation, a readable debugging report is automatically generated to improve the debugging efficiency.

具体实施方式Detailed ways
下面结合具体实施例对本发明作更进一步的说明。The present invention will be further described below in conjunction with specific examples.
(1)在现场配电终端安装到位的前提下，使用模拟主站进行现场就地调试能够摆脱对通信的依赖，实现终端就地快速与主站联调。模拟主站调试系统利用调试子系统调试态模型、自动点表生成技术，与实际运行主站同步技术，实现配电自动化模拟主站系统前置采集与实时数据处理。通过模拟主站在现场实现与运行主站完全一致的调试环境，验证“三遥”、终端配置参数、规约配置等的正确性，保证与主站端验收标准、流程一致，实现配电自动化快速就地调试；(1) On the premise that the on-site power distribution terminal is installed in place, using the analog master station for on-site debugging can get rid of the dependence on communication, and realize the joint debugging of the terminal on site and the master station. The simulation master station debugging system uses the debugging state model of the debugging subsystem, the automatic point table generation technology, and the synchronization technology with the actual running master station to realize the pre-acquisition and real-time data processing of the power distribution automation simulation master station system. By simulating the master station on site to achieve a debugging environment that is completely consistent with the running master station, verify the correctness of "three remotes", terminal configuration parameters, protocol configuration, etc., ensure that it is consistent with the master station's acceptance standards and processes, and realize power distribution automation quickly in-place debugging;
(2)部署模拟主站系统调试系统、部署基于配电自动化主站的配电终端信息全过程自动化接入功能模块，实际运行主站根据终端厂家上送的信息交互的结果各自生成模型配置文件，然后实际运行主站根据配电终端自描述文件信息更新主站系统的数据库，制定基于“三遥“的标准点表，进而通过配电主站管理工具exp_man进行模型同步、通过Graph文件图形同步至模拟主站。在现场就地调试时，配电终端调试人员可根据现场情况，与模拟主站内的信息进行核对；(2) Deploy the simulation master station system debugging system, deploy the distribution terminal information whole-process automatic access function module based on the distribution automation master station, and the actual operation master station generates model configuration files according to the information interaction results sent by the terminal manufacturer , and then the actual running master station updates the database of the master station system according to the self-description file information of the power distribution terminal, formulates a standard point table based on "three remotes", and then performs model synchronization through the power distribution master station management tool exp_man, and graph synchronization through the Graph file to the analog master. During on-site commissioning, the commissioning personnel of the power distribution terminal can check with the information in the analog master station according to the site conditions;
(3)规定标准化配电自动化就地调试流程，统一现场调试接线上送数据的顺序，从而保证现场接线线序的正确性。根据现场情况，在模拟主站内输入过流过负荷的额定值，自动判断是否存在过流过负荷情况、CT(电流互感器)设备是否能够正常工作和过流过负荷告警信号是否能够正常发出；(3) Standardize the on-site commissioning process of power distribution automation, and unify the sequence of sending data for on-site commissioning wiring, so as to ensure the correctness of the on-site wiring sequence. According to the site conditions, input the rated value of overcurrent and overload in the analog master station, automatically judge whether there is an overcurrent and overload condition, whether the CT (current transformer) equipment can work normally, and whether the overcurrent and overload alarm signal can be sent normally;
(4)通过自动化生成终端调试报告的方法，结合现场终端调试报告需求，自动生成终端调试结果报告，报告中显示在配电终端就地调试过程中可能出现的一切故障，如接线顺序错误、告警信号无法生成、电流互感器精确度不合标准、开关变位与遥信信号不即时对应等问题。在此再次重申规范化调试流程的重要性，调试过程中遥信信号和遥测数据上送顺序与规定的上送顺序产生的偏差，在生成的调试报告中会显示现场接线错误；(4) Through the method of automatically generating the terminal debugging report, combined with the requirements of the on-site terminal debugging report, the terminal debugging result report is automatically generated, and the report shows all possible faults that may occur during the on-site debugging of the power distribution terminal, such as wrong wiring sequence, alarm The signal cannot be generated, the accuracy of the current transformer is not up to standard, and the switch displacement and the remote signal do not correspond immediately. Here again, the importance of standardizing the debugging process is reiterated. During the debugging process, the deviation between the sending sequence of the remote signaling signal and telemetry data and the specified sending sequence will cause on-site wiring errors to be displayed in the generated debugging report;
使用现场主流终端任一厂家配电终端如FTU、DTU各一台，建立符合该项目配电终端联调、验收标准体系，用于与就地模拟主站系快速联调测试和配电自动化主站的全过程快速接入。检验时，通过更改FTU、DTU上送信号量、变更调试加量顺序、变换终端保护定值等干扰因素验证模拟主站进行配电自动化就地调试方法的可靠性。Use one distribution terminal from any manufacturer of mainstream terminals on site, such as one FTU and one DTU, and establish a joint commissioning and acceptance standard system for the power distribution terminal of the project, which is used for fast joint commissioning test and distribution automation main Quick access to the whole process of the station. During the inspection, the reliability of the on-site debugging method for power distribution automation by the simulated master station is verified by changing the signal volume sent by the FTU and DTU, changing the order of debugging and increasing the amount, and changing the terminal protection setting value and other interference factors.
