The power systems become more and more complex for the tendency to be interconnected and large scale. It is very important to detect symptom in the early of large scale blackouts and take necessary precaution measures. The analysis and control of complicated systems can not be completely solved by only mathematic tools or knowledge-based method for the reason that power systems are typical hybrid...
In this paper a novel power system alarm processing and fault diagnosis expert system (AFDES) is presented. For the application of expert system (ES), there is a bottle-neck problem to obtain a maturing rule-base. Backus-Naur Form (BNF) is used to design a kind of expert rule frame which operator can write and add the rules with his own defining language to rule-base in ES. By this way a maturing...
Blackouts caused by accidents can not be avoided completely while power grid is becoming larger and more complex. So how to analysis faults and find out the reason and the location as fast as possible, then take exact measures to reduce outage scope and duration, is a very important issue. Local alarm processing and fault diagnosis system can deal with local faults with local information. But there...
