摘要
论述了西门子锅炉给水泵汽轮机控制系统在发电厂的使用情况,介绍了该系统的控制原理,集中描述了转速脉冲信号(转速测量值)、转速设定值的形成,最终实现锅炉给水泵汽轮机转速控制指令的全过程。结合该系统在发电厂给水泵汽轮机中的具体应用情况,对运行过程中存在的问题及处理方法进行了简要说明。
The service condition of control system of the steam turbine for boiler feedwater pump produced by Siemens was discoursed.The control principle of the system was introduced.The all process,in which includes the measurement of speed impulse signal,the formation of speed settings,and the creation of control instruction for the steam turbine speed,were described in detail.Combining with the concrete service condition of the system in steam turbine for feedwater pump,some problems occurred in operation and handling methods were explained tersely.
