Service oriented architecture (SOA)-based grid equipment monitoring and failure positioning wireless system

Abstract

The invention discloses a service oriented architecture (SOA)-based grid equipment monitoring and failure positioning wireless system. The system comprises an information acquisition module, a data processing module, a communication module, a power module and a background processing module, wherein the information acquisition module acquires the running state parameters of grid equipment and transmits the acquired parameters to the data processing module; the data processing module processes and displays the parameters and transmits the processed grid equipment data to the background processing module through the communication module and the Internet network; the background processing module monitors the received grid equipment data and positions a failure; and the power module is connected with the information acquisition module, the data processing module and the communication module. The system adopts a wireless sensor network, is connected with the Internet network, is applied to global position system (GPS) technology and geographic information system (GIS) technology, monitors the grid equipment and positions the failure in real time, meets the requirement of safe operation of the traditional electric distribution network and can be widely applied to the electric distribution network.

Description

technical field [0001] The invention relates to a grid equipment monitoring and fault location system, in particular to a grid equipment monitoring and fault location wireless system based on SOA architecture. Background technique [0002] In distribution network automation system, fast fault location and isolation is one of the most important components. The relay protection of my country's distribution network generally adopts a staged protection method based on current and voltage, and locates the fault point according to the preset setting value. [0003] With the continuous development of the distribution network, the network is becoming larger and more complex, and the fault handling of the distribution network has always been a difficult technical problem to solve. The power supply distance of urban substations is generally only 3-5km, which is divided into 3-5 sections by section switches. It is more and more difficult to use traditional overcurrent, distance and o...

AI Technical Summary

Problems solved by technology

It is more and more difficult to use traditional overcurrent, distance and other staged protection setting coordination on such a short line. As a result, any fault on the line requires the tripping of the circuit breaker at the outlet of the substation, resulting in a power outage of the entire line, expanding the power outage area, and reducing The reliability of distribution network operation

Especially with the access of new energy to the distribution network, the unidirectional power flow of the traditional distribution network has been subverted, making it more difficult for traditional distribution network protection to determine the fault section

Therefore, the traditional fault location method can no longer meet the requirements, and a new fault location method is needed to solve the problem of safe operation of the current distribution network.
