Abstract: Using dummy unit modeling with distributed components and real-time data processing, we propose an open system framework to support economic operation of power plants. Key modules are implemented by using the framework for such functions as economical operation analysis, cost accounting, real-time data processing, fuel and equipment management, information briefing and human-machine interaction. As a case study, coal consumption of a thermal power plant is analyzed, showing that the key modules work normally in a distributed computing environment. The system can provide technical support for power plants in resource allocation and economical operation.

Key words: coal consumption, economical operation, system framework, dummy unit
