In this paper, an expert system is developed to provide a quick and best strategy of load transfer for the power system operator. This load transferring problem is then constrained by the firm and normal capacities of a bank, the fault history of a bank, and the feeder priorities. Heuristic rules which are obtained from a substation operator and both DDC (Distribution Dispatch Center) and DDC (Distribution Control Center) engineers, are incorporated in an expert system to improve the solution procedure. Furthermore, the structural rules based on the bus topology are also generated to reduce the number of switching required to reallocate the load from the busbar connected to the faulted bank to the other sections. This expert system is implemented in Prolog, and the best-first search method is adopted. To solve the combinatorial problem, list processing and recursive programming techniques are used. We also employ the pattern matching mechanism to trace the feeder connectivity.
