  • Patent number: 5966925
    Abstract: A method of controlling a gas turbine electric power plant comprises the steps of: prescribing the relationship between a time elapsed after a predetermined reference time (e.g., ignition time) in a predetermined process (e.g., the starting process) and a revolution speed of a turbine shaft in accordance with a first function (7); prescribing the relationship between a revolution speed of the turbine shaft and a flow rate of fuel to be supplied to a combustor (4) in accordance with a second function (10); measuring an actual revolution speed of the turbine shaft at the time elapsed; rotating the turbine shaft by a starting equipment (6) for driving the turbine shaft in such a way that the measured actual revolution speed becomes the revolution speed corresponding to the time elapsed prescribed in accordance with the first function; and obtaining a flow rate of fuel corresponding to the actual revolution speed in accordance with the second function, to supply the obtained fuel flow rate to the combustor (4).
