摘要
With the rapid increase in the demand for power, equipping power systems with distributed energy resources (DERs) has become a trend. In addition, fault current limiters (FCLs) may be installed to prevent the short circuit current from exceeding the current capacity of the power equipment. However, those mentioned above have a strong influence on the protective system. This paper proposes overcurrent protection strategies for distribution systems with DERs and FCLs. Via the proposed approach, the relays with communication ability can determine their own operating states on the basis of a proposed fault index and decision procedure. The performance and effectiveness of the proposed overcurrent protection strategies are verified by implementing three distribution systems. Simulation results reveal that the proposed strategies are effective for the protective schemes of the power systems with DERs and FCLs.
