Title:
LOAD CONTROL DEVICE FOR COMBINED CYCLE GENERATOR PLANT
Document Type and Number:
Japanese Patent JPS6073003
Kind Code:
A
Abstract:
PURPOSE:To make it possible to easily conduct desired load limiting, by providing a load limit setting device for generating a desired load limiting value and a low-value selecting device for generating an output to a fuel control command operator. CONSTITUTION:Difference 22 between a load command 20 and a generator output 18 is obtained by an adder 19. Matching between a rated speed set value 26 and an actual speed 24 is effected by an adder 25. An output 35 from a load setting device 33 is added to an output 34 from a multiplier 31 by an adder 39, and an output 43 from the adder 39 is fed to a low-value priority device 44. An output 42 from a load limit setting device 41 is compared with the output 43 from the adder 39 by the low-value priority device 44, and a low value 45 is generated. Matching between the signal 45 and a no-load rated speed 37 is effected by an adder 46 to generate a control valve opening command 40. Thus, a desired load limiting may be easily conducted.
