变转速抽水蓄能机组控制策略选择

Control Strategy of Variable Speed Pump-Turbine Units

文章从变转速抽水蓄能机组特性及建设目的出发、讨论了变转速抽水蓄能机组控制策略,推荐采用变流器控制功率,调速器控制转速的控制策略,最后讨论了变转速抽水蓄能的启停策略,希望对以后工程建设有借鉴作用。

Based on the characteristics of variable speed pumped storage units and the problems of power grid under large-scale new energy situation,the control strategy of variable speed pumped storage units is discussed in this paper.The control strategy of power controlled by converter and speed controlled by governor is recommended.finally,the paper discusses the start-stop strategy of variable-speed pumped storage,which is expected to be used for reference in the future engineering construction。
