| 摘 要： | 采用串联谐振型故障电流限制器(fault current limiter,FCL)是解决超高压电网短路电流超标问题的一种新技术手段。文章介绍了华东500kV电网FCL示范工程的选址和主要参数设计等基本情况,阐述了基于晶闸管保护串联电容器(TPSC)技术的FCL的基本原理和主体结构,以及FCL控制保护样机的系统结构和主要功能,详细描述了样机所采用的各类保护配置,并分析了FCL对系统继电保护的影响。对保护配置中最具代表性的线路过电流瞬时保护和金属氧化物限压器(MOV)过电流保护试验数据进行了分析,验证了FCL控制保护样机保护配置的合理性和实用性。

| Abstract: | The series resonant type fault current limiter is a new technology to limit the excessive short-circuit current of the extra high voltage power grid. This paper firstly provides the basic information of the fault current limiter(FCL) which will be installed in East China 500kV Power Grid,such as site- selection and basic parameter design. Then followed by the fundamental principles and main structure of the FCL which based on the technology of TPSC (Thyristor Protection Series Capacitor),a detailed introduc... |
