Description

Substation network monitoring system

Technical Field

The invention relates to the field of monitoring systems, in particular to a substation network monitoring system.

Background

In the power industry, substations are locations where voltage is changed. In order to transmit the electric energy generated by the power plant to a remote place, the voltage must be increased to become high voltage, and then the voltage is decreased as required near the user, and the voltage increasing and decreasing work is completed by a transformer substation. The main equipment of a substation is transformers and switches. The kinds and the quantity of the transformers and the switches are various, and the parameter information of the transformers is inconsistent, so that great inconvenience is brought to management and maintenance.

The distribution of the transformer substations is relatively dispersed, so that the number of the transformer substations is large; and many are distributed in suburb areas and vast rural areas, and the current common method is manual inspection tour. The traditional manual inspection mode has high labor intensity and low working efficiency. Although manual inspection can be used for directly inspecting the power transmission and transformation equipment, the problem hidden danger existing in the power transmission and transformation equipment cannot be detected in real time, the detection frequency is limited by the number of inspection personnel, and the labor cost is increased if the detection frequency is increased.

With the development of network monitoring technology, the daily maintenance of the transformer substation is developed to be possible from manual monitoring to remote monitoring and automatic system adjustment.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are described herein for the purpose of illustration and explanation and not limitation.

Example 1

The invention provides a network monitoring system of a substation, which comprises

And the monitoring and data acquisition module is used for monitoring the actual power transformation line condition in the power transformation station and acquiring fault information. Generally, the monitoring and data collecting module mainly monitors lines and transformers in an actual substation, and collects working parameters of the lines and transformers, including information such as current and voltage.

The execution module is used for uploading fault information and receiving a control instruction; and controlling the on-off of the switch in the power transformation circuit according to the control instruction. The execution module is generally a control part arranged in the transformer substation, plays a role of 'starting and stopping up', and mainly collects and uploads fault information at the lower end, receives a control instruction and executes the control instruction downwards.

And the control module is used for identifying the acquired fault information, determining the fault type, replanning the execution path of the power transformation circuit according to the fault type and converting the execution path into a control instruction. The control module is an upper computer positioned at a background and can judge the type of the fault and search a solution according to the type of the fault so as to control the execution module to change the execution path of the power transformation circuit and ensure the normal work of the transformer substation.

In the design of an actual system, for convenience of planning a new execution route, fault types are mainly divided into a sectional line fault and a transformer fault. Because the power transformation line is generally complex, the whole power transformation line is divided into different sections, for example, a fault corresponding to a fault in the a-B section corresponds to afault 1, a fault corresponding to a fault in the B-C section corresponds to afault 2, a fault corresponding to a fault in the C-D section corresponds to a fault 3, a fault corresponding to a fault 4 in thetransformer 1, a fault corresponding to a fault 5 in thetransformer 2, and the like, and such fault division facilitates the control module to re-plan the execution path of the power transformation line.

And the database module is used for storing the fault information and the solution corresponding to each fault type. Generally, when a power transformation line of a transformer substation is fixed, common faults of the power transformation line can be determined according to experience of inspection personnel, so that a solution corresponding to each fault is determined, the fault and the solution corresponding to the fault are recorded in a database, once the control module identifies which type of fault is, the solution corresponding to the type of fault can be obtained from the database, and an execution route of the power transformation line is planned again.

And the data transmission module is used for information interaction between the control module and the execution module. The data transmission module is a bridge between the communication control module and the execution module, and the communication mode can be wired or wireless. And when the wireless communication mode is adopted, one communication mode, such as WIFI, 2G, 3G, 4G or GPRS, can be adopted independently, and two or more wireless communication modes can be selected to be combined.

In order to facilitate the system to prompt fault information, the monitoring system also comprises an alarm module; and the alarm module is used for generating corresponding real-time alarm information according to the real-time fault type to alarm. The alarm information comprises an alarm signal, an alarm lamp and the like.

In order to clearly and vividly demonstrate the execution conditions of the power transformation circuit before and after the fault, the monitoring system also comprises an animation display module; and the animation display module is used for displaying the actual execution path, the specific fault type, the real-time alarm information and the re-planned execution path of the power transformation circuit in the power transformation substation in the form of animation when the fault occurs.

In order to facilitate the export of data, the monitoring system also comprises a report module; the report module is used for generating a data report from the fault information, wherein the data report comprises a real-time data table and a historical data table.

The substation network monitoring system ofembodiment 1 is based on the popularization of computers and the development of various computer software, and completes the monitoring of the power grid and the processing of simple problems through a computer human-computer interface. This monitored control system can carry out real time monitoring to the transformer line in the transformer substation to the fault information who will gather passes through data transmission module and transmits to the host computer, and the host computer judges the fault type, provides the solution, through closed or open relevant switch, adjusts the execution route of transformer line, thereby reaches remote monitoring, automatically regulated's purpose, great saving manpower resources, but also great improvement factor of safety.

Example 2

The difference betweenembodiment 2 andembodiment 1 is that the control module, the data transmission module, the execution module and the monitoring and data acquisition module inembodiment 2 are arranged in a one-to-many manner. By the arrangement, all substations in a certain area can be connected with the same control module, and one control module controls a plurality of substations to normally work, so that the structure of the system can be effectively reduced, the utilization rate of an upper computer is improved, and the cost of the system is reduced.

The foregoing is only a preferred form of the invention and it should be noted that several similar variations and modifications could be made by one skilled in the art without departing from the inventive concept and these should also be considered within the scope of the invention.
