摘要
根据国产600 MW超临界机组常见的给水泵最小流量阀的特点,分析了常用最小流量控制方法存在的问题,并提出一种基于函数控制的控制方案,即对最小流量阀进行连续控制的方法,以改善给水泵的工作条件。
Aiming at the features of conventional minimum-flow valves for feed pumps of domestic 600 MW supercritical power units, problems existing in the minimum-flow control method are being analyzed, to which a control strategy is proposed based on function control, i.e. by continuous control on the minimum-flow valve, so as to improve working conditions of relevant feed pumps.
