Integrated control system and method

An integrated control system (104) for use with an engine (106) connected to a generator (108) providing electrical power to a switchgear (110) is disclosed. The engine (106) receives gas produced by a gasifier (102). The control system (104) includes an electronic controller (148) associated with the gasifier (102), engine (106), generator (108), and switchgear (110). A gas flow sensor (176) monitors a gas flow from the gasifier (102) to the engine (106) through an engine gas control valve (144) and provides a gas flow signal to the electronic controller (148). A gas oversupply sensor (170) monitors a gas oversupply from the gasifier (102) and provides an oversupply signal indicative of gas not provided to the engine (106). A power output sensor (172) monitors a power output of the switchgear (110) and provide a power output signal. The electronic controller (148) changes gas production of the gasifier (102) and the power output rating of the switchgear (110) based on the gas flow signal, the oversupply signal, and the power output signal.
