Abstract

PURPOSE: To automatically increase the speed of slow rotation without vibration, by controlling the speed depending on the lower of the output signals of a low speed reference circuit and a speed control circuit at slow running.
CONSTITUTION: This controller comprises a speed detector 54 which detects through an electromagnetic pickup 58 the speed of steam turbine 46 driven by steam from a boiler 40, a speed setting unit 62 for setting a reference speed for the turbine 46, the speed control circuit 66 which generates a speed control signal on the basis of the difference between the set speed and the detected speed, a low reference speed setting unit 68 for setting a reference speed for slow rotation of the turbine, and a lower level priority circuit 70 which receives the outputs of the speed control circuit 66 and the low reference speed setting unit 68 and transmits the lower of the outputs. A driver 76 has an actuator 86 to open or close a steam regulating valve 44
