INTEGRATED CONTROL SYSTEM AND METHOD
First Claim
1. An integrated control system for use with an engine connected to a generator, the generator providing electrical power to a switchgear, the engine operating using a gas produced by a gasifier that is associated with the engine as a fuel source, the integrated control system comprising:
- an electronic controller operably associated with the gasifier, the engine, the generator, and the switchgear;
a gas flow sensor disposed to monitor a gas flow from the gasifier to the engine through an engine gas control valve and provide a gas flow signal indicative of the gas flow to the electronic controller;
a gas oversupply sensor disposed to monitor a gas oversupply from the gasifier and provide an oversupply signal indicative of the gas oversupply to the electronic controller, wherein the gas oversupply is a portion of the gas flow from the gasifier that is not provided to the engine;
a power output sensor disposed to monitor a power output of the switchgear and provide a power output signal indicative of the power output to the electronic controller;
wherein the electronic controller is disposed to change a gas production of the gasifier and change a power output rating of the switchgear based on the gas flow signal, the oversupply signal, and the power output signal.

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

14. A method for the coordinated control of a system including a gasifier connected to an engine, the engine driving a generator connected to a switchgear that provides electrical power to a grid, the engine being configured to operate using a fuel provided to the engine in gaseous phase from the gasifier, the method comprising:
-
monitoring a gas flow from the gasifier to the engine through an engine gas control valve to provide a gas flow signal indicative of the gas flow; monitoring a gas oversupply from the gasifier to provide an oversupply signal indicative of the gas oversupply, wherein the gas oversupply is a portion of the gas flow from the gasifier that is not provided to the engine; monitoring a power output of the switchgear to provide a power output signal indicative of the power output; changing, independently, a gas production of the gasifier and a power output rating of the switchgear based on the gas flow signal, the oversupply signal, and the power output signal. - View Dependent Claims (15, 16, 17, 18, 19, 20)
