Abstract:
1. A method of controlling a transition of a gas turbine, said method including: receiving a request of the gas turbine to drive an increased load, wherein said increased load is greater than a load being driven by said gas turbine when said request is received; determining that a temperature of a fuel to be ignited within a combustor of said gas turbine is less than a target temperature of said fuel to be introduced into said combustor for driving said increased load; controlling introduction of an additive into said combustor of said gas turbine to introduce a first quantity of said additive into said combustor concurrently with heating of the fuel when said temperature of said fuel is less than said target temperature to establish a suitable Wobbe Index of a fuel combination to promote a substantially continuous transition of the gas turbine to drive the increased load, wherein said fuel combination includes the fuel and the additive; and controlling said introduction of the additive to reduce an amount of the additive being introduced to the combustor from the first quantity to a second quantity that is less than the first quantity in response to a determination that the temperature of the fuel has been elevated to the target temperature.
