摘要
分析了当前国内电力系统330 kV及以上电压等级断路器辅助保护瞬时跟跳逻辑存在的问题,针对存在问题,提出对330 kV及以上电压等级断路器辅助保护跟跳逻辑改进方案,规范、统一了断路器辅助保护瞬时跟跳逻辑,提高了系统故障时断路器跳闸的可靠性,有利于电力系统稳定运行。
This paper analyzes the problems in the instan-taneous linkage tripping logic of circuit breaker auxiliary protec-tion for the 330 kV and above power systems in china.Targeting at the existing problems,the paper proposes an improvement program,which can not only standardizes and unifies the ins-tantaneous linkage tripping logic of circuit breaker auxiliary protection,but also improves the reliability of the circuit breaker tripping during a power system fault.The proposal described in the paper is conducive to the stable operation of the power grid.
