초록
This paper describes the effect of the interconnected wind turbine generators on fault current level of distribution networks. Distributed generator(DG) interconnected with grid can supply the power into a power network not only the normal conditions, but also the fault conditions of distribution network. If the fault happened in the distribution power line with DG, the fault current level measured in a relaying point might be higher than that of distribution network without wind turbine generator due to the contribution of wind farm. Consequently, it may destroy the conventional protective devices applied in the distribution network with DG. Simulation results shows that the current level of fault happened in the power line with DG depends on the power output of DG.
