摘要
介绍了在运行过程中出现的阀门流量特性曲线问题导致机组负荷波动的情况.分析了负荷波动的原因。认为在DEH系统中,如果阀门特性曲线在设定中存在偏差,将对机组的协调控制产生很大影响,甚至使机组负荷出现波动。
The problem of load fluctuation caused by valve flowrate characteristic curve during operation is introduced and the causes are analyzed.In the DEH system,if the valve characteristic curve has deviation in setup,it will have a big impact on the coordinated control of the unit and even cause fluctuation in unit load.
