Abstract
A turbine mechanical output computation device computes a gas turbine mechanical output P from the following equation where Pe represents a generator effective power measured by a generator effective power wattmeter, N represents the rotational speed of a gas turbine measured by a gas turbine tachometer, J represents the moment of inertia of the gas turbine, and g represents gravitational acceleration. A combustion air amount controller controls the amount of combustion air based on the gas turbine mechanical output P.
