摘要(Abstract):

针对某电厂一起发电机甩负荷试验引起发电机频率异常保护动作的情况,分析了发生频率异常的原因,以及过频率和低频率对发电机产生的不同影响,提出了对频率异常保护整定配置的改进措施。
Based on the abnormal action of generator frequency protection in the load rejection test in a power plant,this paper analyzes the causes and the different influences of the over-frequency and low frequency on the generator,puts forward the improvement measures of setting configuration of abnormal frequency protection.
