Abstract

PURPOSE: To provide an electronic oil pressure type governor for feedback controlling a steam turbine by a load signal, wherein an auxiliary setter to correct the load signal is provided, thereby to perform an appropriate control with respect to the load signal.
CONSTITUTION: The controlling part of a steam turbine is indicated by broken line, and a signal from a load setter (main setter) 60 for setting a load commanding value which is used as a reference for the load variation quantity is supplied as input to a computing part 63. Further, a signal from a speed setter 61 is supplied as input through a governing factor computing part 65 to a low value priority circuit 66, and, at the same time, a signal from an auxiliary setter 64 for setting the upper limit value of the output of the computing part 65 is supplied as input to the circuit 66, where the lower value is added to the signal of the setter 60. The corrected signal operates speed regulator driving units 7 and 28 through load distributers 38, 42, comparing parts 39, 43 and adjustment control parts 40 and 44, thereby to feedback control the regulating valves 3 and 26.
