摘要： PROBLEM TO BE SOLVED: To provide a detection method of more precise power-load unbalance of a steam turbine.
SOLUTION: The combined cycle power plant includes high-, medium- and low-pressure steam turbines 3, a gas turbine 1, and a power generator 4 which are directly connected on a same axis, and includes an exhaust heat recovery boiler 5 for generating steam by recovering exhaust gas of the gas turbine 1. A steam turbine output is calculated based on a steam pressure obtained by weighted average of a first steam pressure 30a and a second steam pressure 32a respectively measured in a first pressure detection position 29a in a downstream of a reheat steam control valve 20 and in a second pressure detection position 31a in a downstream of the first pressure detection position. A turbine output is obtained by adding the steam turbine output to a gas turbine output. A power generator output is subtracted from the turbine output. A remote load interruption detector 25-1 detects the power-load unbalance when deviation between the turbine output and the power generator output exceeds a previously set prescribed value.
