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. © State Grid Electric Power Research Institute Press.
