要約(日本語): Traditional protective relaying in distribution networks is based on large increase of current during faults. Three-stage over current protection consisting of instantaneous, time delay instantaneous and definite time over current protection coordinately work together and have enough reliability, selectivity, speed and sensitivity.However, when more and more distributed energy sources (distributed generators, DGs) are connected to distribution network, traditional protection strategies face strict challenges. This paper is mainly for specifically explaining the impacts caused by distributed energy resources to protective relaying of distribution network and simply introduces some new idea about the protection relaying of new distribution network.
