摘要：
Renewable sources such as solar and wind is the ideal solution for sustainable development. However, protection methods for renewable energy penetrated power systems still faces a lot of challenges. We claim that the performance of the differential protection is highly related to the model accuracy. Using a detailed distributed parameter line model, this paper developed a novel differential protection method for renewable energy penetrated power systems based on traveling waves with high rapidity and reliability. The optimal differential point is also discussed to enhance protection rapidity. Experiments demonstrate that the proposed protection could soon detect internal faults with high fault resistance while maintaining reliability when external faults occur.
