摘　　要：发电机在运行过程中,氢气纯度下降对机组安全运行造成严重威胁。若氢气纯度下降至爆炸极限范围内,可能引起发电机内氢气爆炸,为电站乃至整个电力系统带来不可挽回的损失。针对某电站发电机组运行过程中氢气纯度下降问题进行系统分析,并提出相关控制措施。实践表明具有一定的可行性,为今后电站处理氢气纯度问题提供依据。Hydrogen purity decline causes a serious threat to safe operation in the process of generator operation which may cause hydrogen explosion inside generator when hydrogen purity falls to the explosion limit. It causes irretrievable losses for power station even the whole power system. According to the problems of hydrogen purity decline for given power station in the operation process,the reasons for the decrease are analyzed systematically and control schemes are proposed. Practice shows that it has certain feasibility which providing a foundation for power plant dealing with hydrogen purity in the future.
