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 op-eration and handling methods were explained tersely.
