Abstract

PURPOSE: To ensure the same rate of speed governing as that at the time of constant pressure operation of a turbine also at its variable pressure operation, by changing gains in a control system on the basis of signals of a main steam pressure for the turbine.
CONSTITUTION: To obtain a movement of a steam control valve, not shown in the drawing, at the time of variable pressure operation equal to a movement at the time of constant pressure operation, a level of gain for a devition signal 4, that is, the output signal of an arithmetic unit 3 that processes the output of a counter 5B, rotational speed signal 2 and speed setting signal may be appropriately adjusted. This is realized by producing a gain preset signal 7 from a conversion formula previously calculated from a steam pressure signal 9 by a setter 8 and changing the level of gain of a counter 5A for the deviation signal 4. While the preset signal 7 passes a reciprocator 10 to become a reciprocal, change the gain of the counter 5B and process a load preset signal 1B. In this way, a constanct rate of speed govering can be always ensured.
