Energy-loss analysis refers to analyzing influence of some parameters deviated from targeted working condition on unit thermal economy during unit operation [1–3]. Coal consumption analysis aiming at thermal power unit controllable parameter changes aims at determining influence extent of controllable parameters on unit performance, thereby providing scientific basis for improving economic operation level of the unit. It acts as one of basic theory work tasks necessary for realizing energy saving and consumption reduction of thermal power unit [4, 5]. Model of coal consumption deviation calculation caused by thermal power unit important operating parameters deviated from the target value is proposed through the study of relation between important controllable operating parameter change in thermal power generating unit and coal consumption. The model can be applied to on-line monitoring system of unit operation thermal economy. “Performance factor” is adopted to evaluate advantages and disadvantages of thermal power unit performance. Concepts of operational performance factor and maintenance performance factor are introduced for distinguishing factors affecting unit operation from factors affecting maintenance. Meanwhile, concepts of “energy loss factor,” “relative energy loss rate,” etc., are proposed in order to further diagnose actual reason of unit energy loss and provide guidance for operation.
