Abstract

The invention provides an intelligent substation centralized relay protection system which comprises a centralized relay protection management platform, a local protection device, a moving device, a monitoring device and a fault recording device. The centralized relay protection management platform, the plurality of local protection devices, the monitoring device and the fault recording device conduct communication through MMS, GOOSE and SV in a dual-network dual-sleeve mode, the monitoring device is used for detecting and controlling the network state, the centralized relay protection management platform has a substation bus fault analysis and protection control function and further has functions of line fault backup protection, line protection, failure protection and substation relay protection platform management. An intelligent substation centralized replay protection method is further provided. The system and method has the advantages of being capable of effectively utilizing secondary system total station information, flexible in protection control means and quick in backup protection action.

Description

technical field [0001] The invention relates to the field of substations, in particular to an intelligent substation centralized relay protection system and protection method. Background technique [0002] With the promotion and construction of smart substations, smart substations present the characteristics of standardized equipment modeling, secondary system networking, and primary equipment intelligence. While the development of smart substation technology changes the organizational form of substations, it also brings about changes in information acquisition methods, information interaction methods and protection control principles for substation relay protection. Under the background of smart substation technology, relay protection emerges as a network-oriented, New principles and new methods of platformization and intelligence. [0003] At present, the substation relay protection is in the process layer of the three-layer structure of the substation. It receives the pr...
