Systems and methods are provided for controlling the rotational speed of a turbogenerator in stand-alone mode to account for a present operating load and a transient reserve capability. A base speed set point may be received, comprising a baseline speed setting for the turbogenerator. A speed offset may be determined comprising an adjustment to the base speed set point required to accommodate the transient reserve capability. An adjusted speed set point may be produced by combining the base speed set point and the speed offset. The rotational speed of the turbogenerator may then be set to the adjusted speed set point.

System and method for efficient load following control logic for a turbogenerator operating in stand-alone mode

A control system and method for controlling the split between premix fuel flow and pilot fuel flow to a combustor in a gas turbine engine so that an acceptable emissions are maintained. Engine speed and exhaust gas temperature are used to obtain a combustor pilot zone temperature that will result in the desired level of emissions. From this pilot zone temperature a desired split between premix fuel flow and pilot fuel flow is obtained and compared to the actual split to generate an error signal. The actual premix fuel flow and pilot fuel flow are then adjusted until the desired split and hence the desired emission levels are obtained.
