摘要
A control device of the gasification combined cycle power plant includes: a casing pressure calculation part that calculates a casing pressure of the gas turbine; a pipe pressure loss calculation part that calculates a pressure loss in the pipe from the flow control valve to a combustor of the gas turbine; an outlet pressure calculation part that calculates an outlet pressure of the flow control valve based on the casing pressure calculated by the casing pressure calculation part and the pressure loss calculated by the pipe pressure loss calculation part; and an opening degree command calculation part configured to obtain an opening degree command for the flow control valve based on a fuel flow rate command for the gas turbine, a calculation result of the outlet pressure obtained by the outlet pressure calculation part, and a measured value of a differential pressure of the flow control valve.
