配电网多级继电保护配合的关键技术研究

Research on Key Technologies of Multilevel Relay Protection Coordination in Distribution Network

随着现代社会不断快速发展,人们对于电力供应的需求不断增长,供电企业须保证配电网正常运行,才能够满足各行各业以及居民生活的用电需求。配电网发展过程中,电力供应的稳定及安全性至关重要。由于配电网设备负荷不平衡等问题,需要配合配电网继电保护关键技术,从而发挥继电保护应用的效果,保证供电稳定性,避免电网故障。对配电网多级继电保护现存问题进行分析,探究配电网多级继电保护配合的关键技术,并对配电网多级继电保护配合的技术模式进行分析,使多级继电保护发挥防护作用,提升配电网可靠性。

With the rapid development of modern society,people’s demand for power supply is growing.Power supply enterprises must ensure the normal operation of distribution network to meet the power demand of all walks of life and residents.In the development process of distribution network,the stability and safety of power supply is very important.Due to the unbalanced load of distribution network equipment,it is necessary to cooperate with the key technology of distribution network relay protection,so as to give play to the effect of relay protection application,ensure the stability of power supply and avoid grid failure.This paper analyzes the existing problems of multi-level relay protection in distribution network,explores the key technology of multi-level relay protection cooperation in distribution network,and analyzes the technical mode of multi-level relay protection cooperation in distribution network,so as to make multi-level relay protection play a protective role and improve the reliability of distribution network.
