In order to analysis complicate, varied steam turbogenerator unit regenerative system, we need general mo-del with fine performance. A novel approach, based on exten-sive exploration of structure and mass and energy balances of regen-erative system, was presented in the paper. Firstly, the heat-balance control unit of feedwater heater and mass and energy equations of extraction steam, feedwater and drain water were redefined, then, a new general regenerative system heat-balance equation was established. The equation meets the condition of mass and energy balances completely and has not any additional iterative parameters. In the following, with the tool of relation matrix, a structure model of regenerative system was proposed. With the structure model, the heat-balance equation can be built from basic directive relations of regenera-tive system and building process is very simple. Finally, a real 125 MW unit has been used for verifying and evaluating the proposed approach. Theory analysis and practice application show the fine generality of the approach. More remarkably, the approach has superiority over conven-tional methods in aspects of model precision, calculation speed and easy implementing.
