核电厂应急柴油发电机安全级电气保护配置研究

Research on Safety Level Electrical Protection Configuration of Emergency Diesel Generator in Nuclear Power Plants

核电厂应急柴油发电机肩负着核安全保障的责任,其安全级电气保护配置原则与常规继电保护配置原则存在一定差异。本文从核电厂应急柴油发电机的设计初衷出发,对比国内外相关标准的要求,采用归纳总结的方法,对其安全级保护的配置原则进行分析、讨论,并基于此,对核电厂应急柴油发电机安全级保护的配置提出建议。

Emergency diesel generators(EDG)in nuclear power plants shoulder the responsibility of nuclear safeguard,the configuration principle of safety level electrical protection is different from regular relay protection.This paper starts from the original design function of EDG,compares the domestic and foreign relevant regulations,and summarize the configuration principle of safety level protection,based on this,some suggestions are put forward.
