Claims

[Claims for Utility Model Registration] After the gas compressed by the compressor is combusted in the combustor, it is supplied to the compressor turbine connected to the compressor via the gas generator shaft to rotationally drive the compressor and the compressor turbine. At the same time, the gas that has passed through the compressor turbine is supplied to a power turbine through a variable nozzle to rotationally drive a power turbine and an output shaft of the power turbine, and the gas is supplied through a variable nozzle to a power turbine and an output shaft of the power turbine. A control device for a gas turbine from which power is extracted, comprising an idle detection means for detecting an idle operation request state of a gas generator shaft and an output shaft of the gas turbine, and an idle detection means for selectively determining a target idle rotation speed of the gas generator shaft and output shaft of the gas turbine. a target idle rotation speed variable setting means for variably setting a target idle rotation speed; and a target idle rotation speed variably set by the target idle rotation speed variable setting means when an idle operation request state of the gas turbine is detected by the idle detection means. an idle rotation speed control means for controlling the idle rotation speed via the variable nozzle in order to bring the actual idle rotation speed closer; a power transmission intermittent means for intermittent power transmission to the load via the output shaft; and the idle detection means. The power transmission intermittent operation is performed only when the idle operation request state of the gas turbine is detected by the controller, and the target idle rotation speed selectively and variably set by the target idle rotation speed variable setting means is a predetermined high rotation speed. A control device for a gas turbine, comprising: power transmission cutoff control means for controlling the means to cut off transmission of power to the load via the output shaft.
