Design of Distribution Network Relay Protection under the Condition of Distributed Power Grid Connection
The wide application of distributed generation in distribution network poses a new challenge to the relay protection design of distribution network.This paper deeply discusses the influence of distributed power supply access on distribution network relay protection,such as the location,capacity and reclosing of distributed power supply access.At the same time,starting with current protection and wide area network overcurrent protection,the current protection of distribution network is improved.The principles of distance protection and longitudinal protection in transmission lines are applied to relay protection.In order to ensure the safe and stable operation of distribution network,the relay protection design of distribution network is carried out from two aspects:adaptive fault area protection design and intelligent protection design,and the protection design scheme is flexibly adjusted according to the actual operation situation of distribution network.
