220kV智能变电站继电保护配置方案研究

Study on Relay Protection Configuration Scheme of 220 kV Intelligent Substation

智能变电站继电系统在构造和内涵上存在差异。智能变电体系中,光纤代替传统的电缆,并借助继电保护体系元件评估和分析继电保护。因此,全面分析智能变电站体系,重点阐述220 kV智能变电站的继电保护方法,以建设智能电网,保证继电智能变电站的稳定运行。

There are differences in the structure and connotation of intelligent substation relay system.In intelligent substation system,optical fiber is used to replace the traditional cable,and relay protection is evaluated and analyzed by relay protection system components.It is necessary to analyze the intelligent substation system comprehensively,focuses on the analysis of 220 kV intelligent substation relay protection methods,so as to build a smart grid and ensure the stable operation of relay smart substation.
