【Abstract】 Making use of the theories of the heat energy equilibrium, equivalent enthalpy drop and difference analysis, the comprehensive efficiencies of boiler, steam turbine, pipeline and assistant machines are computed to gain the unit’s economical indexes. On the basis of it, the functions of the on-line economical performance monitoring and energy loss analysis system for power generating unit are realized. The system can help the operators and managers to know the real-time states, economical performances of the unit. It is also one of the major means taken by thermal power plant to realize the economical operation and strengthen the production management.更多还原
