CONVENTIONAL AND KNOWLEDGE-BASED APPROACHES IN FAULT-DIAGNOSIS AND SUPPLY RESTORATION FOR POWER NETWORK

A versatile distribution system simulator integrating load flow, fault current calculation and modeling of overcurrent relays and breaker op eration is described. Appropriate sets of scenarios are generated for different levels of exercise and ail actions taken by the students are logged, evaluated and awarded a grade. The simulator is then configur ed to link to a knowledge based system and the students can attempt to diagnose fault and restore supply using a knowledge base approach. Th rough a series of hands-on exercise, the students strengthen their und erstanding of generic diagnostic rules, restoration algorithms, knowle dge acquisition and inference mechanism.
