摘　　要：3类典型RB工况之一的给水泵RB一直是RB的控制难点,且试验成功率不高,通过对茂名热电厂300MW机组满负荷下的两次给水泵RB工况失败原因的分析,对如何提高给水泵RB工况成功率的RB控制策略的关键点进行了探讨和总结,并提出了改进方法,以提高机组给水泵RB工况成功率、降低机组跳闸风险。As three kinds of typical RB processes,the RB of feed water pump has been the control difficult point of RB processes and the experimental success rate have not been high all the time. This paper research and analysis on the twice failures of feed water pump RB process under a full capacity of the Maoming 300MW Unit,and put forward a improvable RB control strategy which can improve the success rate of the feed water pump RB process and decrease the tripping risks.
