Application of Rough Set Theory in the Fault Diagnosis of Distribution Line
Based on the rough set theory, a new distribution network fault diagnosis approach to deal with the imperfect alarm signals that caused by malfunction or failing operation of protection relays and circuit breakers, error in the communication equipment is proposed. Due to rough set theory can effectively handle the imprecise problems without any ancestor information except the data set itself, a decision table including all kinds of fault cases is established by considering the signals of protection relays and circuit breakers, and the approach can extract diagnosis rules from the set of fault samples directly. The inherent redundancy in the alarm information is exposed. Finally, a practical fault diagnosis program of the typical distribution network is proposed based on VC#. The result shows the validity of the proposed method.
