【 摘 要 】

In order to solve the problem that the traditional single location method has a relatively small scope of application, a method of fault section location in distribution networks based on comprehensive criteria is proposed. Firstly, fault direction measures are proposed to characterize the severity of fault information in different sections. Then the reliability of fault direction measures is quantitatively determined to measure its compliance with the fault law. Based on different prominence of criteria under diverse conditions, criterion measures are proposed to judge the reliability of different criteria. Finally, the fault index of each section is obtained. Simulation results indicate that the method is adaptable to complicated conditions such as different angles of the initial voltage at the fault point, transition resistance and so on.
