| Abstract: | With the Distributed Generation （DG） paralleling into the distribution system, the structure, power flow and the characteristic have changed after failure of power system. So DG has brought a certain impact of protective relaying to the traditional distribution. The major factors which affect the relay characteristic, such as the type of DG are analyzed. The Power System Analysis Software Package （PSASP） is used to simulate the distribution network which is paraUelled to the DG. Adjustments are needed for traditional protective relaying scheme. |
