摘要
This paper focus on how distributed generation (DG) may impact on the fault detection and location in medium voltage (MV) distribution networks. Typical possible problems are protection blinding and sympathetic tripping. The purpose of the work is to gain an understanding of when problems are most likely to occur, and of possibilities for fault location in networks with distributed generation. The paper presents simulations (PSCAD/EMTDC) done on a MV radial distribution network with a DG-unit (synchronous generator). An analytical approach is used to explain simulation results.
