Abstract As distributed generations are connected to the distribution grid leading to the change of the detected current for protection relay .With an example of DG parallel into the distribution network by 35 kV feeder line, the paper depicts the contrast curve of the three-phase short circuit fault current happend to different positions before and after DG access.The optimum capcity ration can be drawn based on the original protection program of three-current protection constraints.Finally ,come to the conclusion that the impacts of DG to the network is related to the fault location and the maximum penetration level of DG.
