Research of the automatic fault location method of rural power distribution network

摘要

The rough set theory is used to realize the automatic fault location method of the rural power distribution network. The decision table of the distribution network fault location is based on the fault complaints information. It is automatically formed by distribution network topology. Then the decision table is property reduced based on identifiable matrix. Finally improved value reduction method is used to derive the simplest form of the decision table, to extract the decision rule, to form the fault diagnosis expert knowledge uniformly. VB language is used to realize the reduction process of the decision table of the distribution network fault location. Combined with the G1S platform, it designs the application program of the fault location and realizes the visual fault localization.
