Design of intelligent fault diagnosis system for energy remote terminal unit based on agent technology

In recent years, Guangdong Power Grid Corporation has built the largest scale electric energy telemetering system in China. More than 400,000 field units had been put into use in Guangdong province. With the scale of system becoming larger, the municipal power supply bureau faces more impression of maintenance work load. In order to decrease the maintenance work load, we have designed and implemented the intelligent fault diagnosis system for field terminal unit based on multi-agent. By using multi-agent technology, the flexible intelligent communication protocol interface and optimal load balancing policy are designed to tackle the problems of various communication protocols and heavy network loads. The production rule knowledge representation is used to build diagnosis knowledge database. The system realized the function of communication monitor and on-line fault-diagnosis, which decreased maintenance work load a lot.
