Relay protection and fault information management system for regional power grid

Abstract

The invention provides a relay protection and fault information management system for a regional power grid. The relay protection and fault information management system comprises a sub-station system and a main station system, wherein the sub-station system comprises a plurality of sub-stations, each sub-station is connected with and monitors secondary equipment, collects the data of the secondary equipment, sends the data to the main station system at a scheduling end, receives a control command of the main station system and sends down the control command to the secondary equipment appointed by the main station system; the main station system comprises a plurality of main stations, is connected with the sub-station system by a communication network, collects the data collected by all the sub-stations and sent by the secondary equipment for fault analysis and sends a control command to the appointed secondary equipment. According to the relay protection and fault information management system, the fault conditions can be grasped timely, comprehensively and accurately in scheduling, so as to process the system fault fast and accurately and provide convenience for the concentrated monitoring and the concentrated management of the operating conditions of a relay protection device for the whole network.

Description

technical field [0001] The invention relates to power grid protection and fault processing, in particular to a regional power grid relay protection and fault information management system. Background technique [0002] In recent years, with the continuous development of the power grid, the power system has higher and higher requirements for safe, stable and economical operation. Timely and accurate analysis of fault and protection action information, and full use of fault data information are of great significance to improving the operation level of relay protection and safety automatic devices. The application of power grid relay protection fault information management system has continuously improved the comprehensive management, analysis and application level of secondary devices. As one of the important analysis methods of power grid, it has been widely used in various power grids, and has gradually produced good economic benefits and functions. As we all know, the occu...

Problems solved by technology

As we all know, the occurrence of the "8.14" blackout in the United States and Canada in 2003 fully shows that there are large loopholes in the power system in preventing major accidents. At the same time, the delay in determining the cause of the accident also shows that the fault information system of the power grid is not perfect.
