摘要
随着分布式电源的大规模接入,配电网保护出现了误动、拒动、失去选择性等问题.文章研究含多种新能源接入的配电网的馈线自动化保护控制方法,可快速实现故障的判别、隔离与供电恢复,提高并网点保护的可靠性,并设计了含分布式电源的配电网控制与保护装置,可以在大量新能源接入新型配电网后,减少对电网的扰动,并在发电侧进行实时智能检测,提高配电网的运行安全性和可靠性.
Abstract
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.
