基于光电式互感器的220kV线路和母线保护配置

Configuration of 220 kV Line and Busbar Protection Based on Photoelectric Transformer

随着电网的不断发展和完善,高电压、大电网模式已经成为供电的主要方式,特别是随着地区电网网架结构的建设,220 kV线路已经是网架结构中的主要组成部分,因此,不断研究和改进220 kV线路保护的配置和设计,是提高保护系统可靠性的要求,更是确保电力系统安全稳定运行的要求,本文在对二次系统深入分析的基础上,提出220 kV线路保护配置和设计的具体方案。

High voltage and regional grid mode had been the main power supply way along side with continuous development and perfection. Especially with construction of regional grid structure, 220 kV line had been the main components of grid structure. So continuous study and improvement of configuration and design of 220 kV line protections were required to improve reliability of protection system and ensure safe operation of power system. Based on deeply analysis on electric secondary systems, detailed protection configuration and design scheme of 220 kV line were posed.
