Controlling co-generation

The control system for the Gulf Oil co-generation project, as well as its design and commissioning are described. The paper first outlines principles which are important to the success of a project. It then uses the Gulf Oil co-generation project to show how some of these may be applied in practice. To fully appreciate the issues involved in the project the overall context needs to be understood. Thus the paper gives an overview of the process and the electrical system. It focuses on the control system. The development of the control system is traced from the high level conceptual design to the detailed design of one component, the modulating boiler control.
