Research on relay protection setting expert system for main equipment in power plant

Protection setting calculation and data management for main equipment in power plant is an important technical foundation for the work. Relay devices of main equipment protection have no uniform criterion and the style of each corporation is distinctive. The setting is time-consuming and laborious with heavy workload. Aiming at the current practical situation, this paper describes the design scheme, module function and technical keys during development of the ES system. Users can use this ES system to realize various functions, such as Main Connection Modeling, Equipment Management, Relay Setting, Fault Analysis and Setting Value Management and so on. Therefore it can reduce the protection setting staff work load and improve work efficiency and quality.
