Compound algorithm applied in fault location in distribution network

When a fault takes place in a distribution network, it's vital for dispatchers to locate the fault as soon as possible. For this purpose, a compound algorithm is proposed appropriate for different distribution networks. It's composed of fuzzy deduction algorithm and expert system algorithm based on heuristic rules. By this compound algorithm, the appropriate algorithm can be chosen according to the different fault information obtained. Because the two algorithms are based on some heuristic rules, it's unnecessary to undertake some complicated calculation, resulting in the great saving of time for fault location and isolation.
