摘要
随着电网的不断发展,输配电系统中不断引入种类繁琐的电力电子设备,其显著的优点是具有快速的反应特性,提高了系统运行的可靠性。然而,它也给供电以及继电保护系统带来了很大的负面影响,造成电网的安全稳定性下降。本文首先分析了继电保护的基本要求,以线路的电流保护为例,阐述电力电子设备对输配网的影响和解决方案。
With the development of grid, A wide variety of power electronic equipments are introducd in power transmission and distribution system. Its remarkable advantage is that its has rapid response characteristic and this characteristic improves the reliability of system operation. However, it also brings a lot of negative effects to the power supply as well as relay protection system and declines the security and stability of the network. This paper analyzes the basic requirements of relay protection and expounds the influence from power electronic equipment to the distribution network. At last, it gives some solutions.
