摘要
Abstract
In order to solve the problem of fault location for distribution systems with distributed generation (DG), the fault current behavior of various DGs and the short-circuit current of the distribution systems with DGs are analyzed. The feasibility of the traditional fault location approach based on the information of overcurrent for distribution systems with DGs is investigated. An improved fault location process is proposed for overhead line based feeders, in which the reclosing procedure and the escape of DGs in case of fault situation are coordinated. Conclusions are drawn on DG connected to the bus and DG connected to the feeders based on cables with an appropriate limit to the total capacity, the fault can be identified with the traditional overcurrent based criteria. As for the case of DG connected to the overhead line based feeder of a rather long distance, it is necessary to utilize the improved fault location process proposed.关键词
