Conventional and knowledge based approaches in fault diagnosis and supply restoration for power network

摘要

A versatile distribution system simulator integrating load flow, fault current calculation and modeling of overcurrent relays and breaker operation is described. Appropriate sets of scenarios are generated for different levels of exercise and all actions taken by the students are logged, evaluated and awarded a grade. The simulator is then configured to link to a knowledge based system and the students can attempt to diagnose faults and restore supply using a knowledge base approach. Through a series of hands-on exercises, the students strengthen their understanding of generic diagnostic rules, restoration algorithms, knowledge acquisition and inference mechanism.
