Abstract
A gas turbine plant for limiting a sudden increase of load of the gas turbine, i.e., of the amount of fuel, and suppressing a stress of the turbine, or for maintaining a suitable fuel-air ratio is disclosed. The plant includes a controller comprising a section for calculating a governor signal for controlling the degree of opening of the fuel valve, based on a revolution speed of the gas turbine; and a section for calculating a load-limiting signal for following the governor signal, wherein when the governor signal decreases, the load-limiting signal is larger than it by a predetermined value, while when the governor signal increases, the increase rate of the load-limiting signal has a predetermined upper limit. The controller also comprises a limiting section, into which both signals are input, for limiting the upper value of the governor signal by using the load-limiting signal as an upper limit.
