Description

technical field

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

Background technique

In the power industry, a substation is a place where voltage is changed. In order to transmit the electric energy from the power plant to a distant place, the voltage must be raised to become high-voltage electricity, and then the voltage is lowered as needed near the user. This work of raising and lowering the voltage is done by the substation. The main equipment in a substation is a transformer and a switch. There are many types and quantities of transformers and switches, and the parameter information of various transformers is inconsistent, which brings great inconvenience to management and maintenance.

Since the distribution of substations is relatively scattered and the number is large; and many of them are distributed in remote suburbs and vast villages, the common method now is manual inspection. The traditional manual inspection method is labor-intensive and low-efficiency. Although manual patrol inspection can directly inspect power transmission and transformation equipment, it cannot detect and discover potential problems in power transmission and transformation equipment in real time, and the frequency of detection is limited by the number of inspectors. If the detection frequency is to be increased, it will inevitably bring Rising labor costs.

With the development of network monitoring technology, the daily maintenance of substations has become possible from manual monitoring to remote monitoring and system automatic adjustment.

Detailed ways

The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

Example 1

The invention provides a substation network monitoring system, comprising

The monitoring and data acquisition module is used to monitor the actual substation line status in the substation and collect fault information. Usually, the monitoring and data acquisition module mainly monitors the lines and transformers in the actual substation, and collects the 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 control instructions; and controlling the opening and closing of switches in the substation line according to the control instructions. The execution module is generally set in the control part of the substation, which plays the role of "connecting the previous and the next", mainly collecting and uploading the fault information at the lower end, receiving control instructions and executing them downward.

The control module is used to identify the collected fault information, determine the fault type, re-plan the execution path of the substation line according to the fault type, and convert it into a control instruction. The control module is the upper computer located in the background, which can determine the type of fault, find a solution according to the type of fault, and control the execution module to change the execution path of the substation line to ensure the normal operation of the substation.

In the design of the actual system, in order to facilitate the planning of new execution routes, the fault types are mainly divided into segmental line faults and transformer faults. Because the substation line is generally more complex, the entire substation line is divided into different sections, for example, the fault of section A-B corresponds to fault 1, the fault of section B-C corresponds to fault 2, the fault of section C-D corresponds to fault 3, and the fault of transformer 1 corresponds to fault 4. The fault of transformer 2 corresponds to fault 5, etc. Such fault division facilitates the control module to re-plan the execution path of the substation line.

The database module is used to store fault information and solutions corresponding to each fault type. Under normal circumstances, when the substation substation's substation line is fixed, according to the experience of the inspectors, the common faults of the substation line can be determined, so the solution corresponding to each fault is also determined, and the fault and the fault corresponding The solutions are recorded in the database together. Once the control module identifies the type of fault, it can obtain the solution corresponding to the type of fault from the database and re-plan the execution route of the substation line.

The data transmission module is used for information exchange 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 its communication method can be wired or wireless. And when using the wireless communication method, one communication method can be used alone, such as WIFI, 2G, 3G, 4G or GPRS, or two or more wireless communication methods can be selected for combination.

In order to facilitate the system to prompt fault information, the monitoring system also includes an alarm module; the alarm module is used to generate corresponding real-time alarm information and alarm according to the real-time fault type. The alarm information includes alarm signal and alarm light, etc.

In order to clearly and vividly demonstrate the execution status of the substation line before and after the fault, the monitoring system also includes an animation display module; Fault types, real-time alarm information, and the execution path of the replanned substation line are displayed in the form of animation.

In order to facilitate data export, the monitoring system also includes a report module; the report module is used to generate data reports for fault information, including real-time data tables and historical data tables.

The substation network monitoring system in Embodiment 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 the computer man-machine interface. The monitoring system can monitor the substation lines in real time, and transmit the collected fault information to the upper computer through the data transmission module. The upper computer judges the type of fault and provides a solution. The implementation path of the electric line, so as to achieve the purpose of remote monitoring and automatic adjustment, greatly saves human resources, and also greatly improves the safety factor.

Example 2

The difference between embodiment 2 and embodiment 1 is that the control module and data transmission module, execution module and monitoring and data acquisition module in embodiment 2 are set up as one-to-many. Such a setting can connect all substations in a certain area to the same control module, and control multiple substations to work normally through one control module, which can effectively reduce the system structure, improve the utilization rate of the upper computer, and reduce the system cost. the cost of.

The above description is only the preferred mode of the present invention. It should be pointed out that those skilled in the art can make several similar deformations and improvements without departing from the inventive concept of the present invention, and these should also be regarded as within the protection scope of the present invention.
