Abstract

PURPOSE: To prevent rapid change of a load at the time of governor free drive by providing a load zone width setting circuit.
CONSTITUTION: A required load signal is set by a supply command signal 1 and an integrator 2. An actual load signal is obtained by a transformer 12 and a current transformer 3. Both signals are compared for the drive of a governor motor 6 to the extent of the deviation through a PID adjuster 4 and a motor driver 5 for adjustment of the load by a turbine 9, a generatot 10, a system breaker 11 through the regulating of steam amount of a boiler 7 by a regulating valve 8. A limitter circuit 15, a zone width switching and upper and lower limit setting circuit 16, a supply command upper and lower limit detectors 17 and 18, and an output upper and lower limit detectors 19 and 20 are provided thereto for setting the upper and lower limit of load control range allowable to the power generation plant against the supply command signal which is the required load signal by the system frequency variation.
