Research on Distribution Control and Protection Method with Distributed Power Supply
With the large-scale access of distributed power supply,problems such as misoperation,rejection and loss of selectivity appear in distribution network protection.This paper studies the automatic protection and control method of feeder lines in distribution network with a variety of new energy access,which can quickly realize fault identification,isolation and power supply recovery,improve the reliability of network connection protection,and design a distribution network control and protection device with distributed power supply,which can reduce the disturbance to the grid after a large number of new energy access.In addition,real-time intelligent detection is carried out on the power generation source side to improve the operation safety and reliability of the power distribution system.
