The Industrial Power Plant Management System - An Engineering Approach

Abstract

Based on energy studies in over 70 plants in the forest products industry, experience has shown that, in addition to process improvements, the most important energy conservation measures in mill power departments are:

- Load shedding and fuel allocation in such a manner that economically optimum conditions are achieved, taking into account purchased power supply.

- Upgrading instrumentation for more accurate information and closer monitoring of plant operation.

To achieve the maximum savings from these measures, a computerized energy management system is often required. This is because the optimum load allocation and best operating point must be determined through continuous energy balance calculations as the demand situation changes. The paper discusses the systems engineering approach to the design of a computerized energy management system. It is based on practical experience focusing on a tailored solution for any industrial power plant, resulting in a concept which is technically and economically feasible.
