| Abstract: | Analysis was made to the capacity impact of distributed generation on the over-current protection of distribution network. Introduction was made to the existing distribution network protection schemes with distributed generation. This paper raised carrying out improvement of over-current protection, the distributed generation upstream equipped with directional element and the current protection setting value of distributed generation downstream modified according to the distributed generation access capacity. Simulation proves it is a feasible method with certain practical value. |
