摘要：
The access of distributed generation to changes the structure, power flow and failure modes of traditional power distribution systems, which may lead to the decrease of sensitivity, malfunction and reclosing of traditional three-stage current protection. etc. Aiming at this problem, this paper based on analyzes the influence of distributed power supply on the relay protection of distribution network, and puts forward the protection scheme of circuit breaker, direction module and inverse time overcurrent protection. Finally, the PSCAD/EMTDC is used to simulate a 10 KV distribution system with distributed generation to verify the effectiveness of the proposed protection scheme.
