Relay protection fault information main station system based on service-oriented architecture

The invention relates to a relay protection fault information main station system based on service-oriented architecture. The system is composed of a plurality of pre communication modules, a service center module, a protocol conversion module, a service distribution module, a plurality of application servers, an interface display module, a data platform module, and a data base server. The multiple pre communication modules e arranged in a plurality of pre communication servers are used for realizing information interaction between a relay protection fault information main station system and relay protection fault information sub stations and sending the obtained information to the service distribution module. The service center module is used for establishing connection between a service consumer and a service provider and balancing connection between a service consumer and service providers when a plurality of service providers exist. According to the invention, the provided system has loose-coupling extensible module combination; and most of modules are stateless independent functional entities and can be deployed to a plurality of communication servers for load balancing.
