Abstract
PURPOSE: To prevent a plant trip from occurring in a device mentioned in the title of a steam turbine plant of a thermal power plant in a manner of shutting off a stopping signal for a pump control switch when a pump standby signal is inputted in a pump-starting system. CONSTITUTION: When the load is low, inputting of a stop signal 57 of a condensate pump A control switch in a circuit of condensate pump stopping system 43 causes a condensate pump A outlet valve full closure-commanding signal 58 to be outputted and a condensate pump A outlet valve to act to close. While this closing is in action, the plant shifts, for example, to independent operation and increases the condensate flow from the condenser. Inputting of a condensate pump A standby-commanding signal 69 to a condensate pump-starting system 42 causes the signal to be transmitted through a control circuit 68 to the circuit of condensate pump stopping system 43, then shutting off a condensate pump A control switch-stopping signal 57. Consequently, a full open-commanding signal 52 is outputted to the condensate pump A outlet valve, making it fully open. In this manner the trip can be prevented.
