Abstract

Running with distributed generation, configuration of distribution network will be changed, that influences strength, flowing direction and duration of fault current. It analysed influence on current protection in main feeder, recloser and conventional branch line protection through the calculation formula of fault current before and after distributed generation synchronization development. In Matlab/Simulink, it constructed distribution network model with distributed generation, used simulation examples to prove influence on current protection and put forward improvement measures which can meet requirements of relay protection in distribution network.
