Abstract: A turbogenerator is controlled by a temperature loop that provides fuel to the combustor to maintain a desired turbine exhaust temperature, and by a speed control loop that controls the speed of the turbogenerator to provide a desired power output. When the desired power output is reduced, the turbogenerator speed is reduced accordingly, and the desired turbine exhaust temperature is increased temporarily to maintain sufficient fuel flow to the combustor to prevent combustor flame-out.

Abstract: A system and method for modular control of a multi-fuel turbogenerator include separate controllers for controlling fuel supplied to the combustor and power output from the generator. The power controller generates a fuel command based on the required turbine exhaust temperature, where the fuel command is independent of the particular fuel being used. Fuels may include natural gas, diesel, propane, waste gas, or gasoline, for example. The power controller communicates the fuel command and the airflow or calculated air/fuel ratio to the fuel controller which selects an appropriate mode of operation for the injectors. Injector operating modes include one or more pilot modes where fuel is not mixed with air prior to combustion, and one or more premix modes where fuel is highly mixed with air prior to combustion.
