It's an important content for management of thermo-economic index of thermal power unit operation,and there are many kinds of management mode. In this paper, the on-line calculating model of the thermal system parameters in off-design condition is consummated. Especially, the calculating model of double back pressure condenser vacuum's datum value is founded; the same time, the inner relation between the affirmations of thermal parameter's target value and total energy-loss assignment is illuminated. Based on the detailed calculating for the thermal system, the energy-loss analytical model is founded. Based on the energy–loss analytical model, the checking model of thermal power unit operation economic index's management, it is also the precondition to realize the thermal power modern management, and it has definite directive meaning for the thermal power economic operation. |
