An expert system for protective relay setting of transmission systems
Seung Jae Lee, Sang Hyun Yoon, Man-Chui Yoon, Jong-Keun Jang · IEEE Transactions on Power Delivery · 1990
An expert system for setting protective relays in a high-voltage transmission system is proposed. Multilevel frames are used to represent relay specifications and system information. Setting rules are stored in the hierarchical rule base. The frame-based inference mechanism is adopted for an efficient integration of framework and rule. An easy system modification environment is achieved through predefined predicates and a frame editor. The use of the system would expedite the relay setting process with increased accuracy and consistency regardless of the power system's complexity.>
