A knowledge-based approach for circuit allocation in subtransmission substations under maintenance conditions

The authors detail the development of a knowledge-based system for allocating circuits to duplicate-busbar switching substations under maintenance conditions. The allocation rules in the knowledge bases for the determination of the arrangements of circuit groups and an overall allocation algorithm for combining the group allocation schemes using the strategy of least reduction in power security are developed The knowledge-based system is applied to a 132 kV substation and the results are presented
