摘　　要：该文提出一种新的电站热力系统数学模型———循环组合法。此法以质量守衡、热平衡为基础，以基本级组与对应加热器构成的回热子循环为环节，形成一套完整的热力系统核算方法。该模型适于系统性能核算，尤其适于构造组态式实时监控软件。此法避免了以往流体网络模型建立完全依赖系统结构和软件维护性能差的问题，符合面向对象组件及组态式软件的要求。Abstract The paper proposes a new mathematical model for heat cycles of power plants——the iteretive combination method. With this method, which is based on the principle of mass conserevation and heat balance, with heat recovery sub loops formed by basic stage groups and their corresponding heaters as links, a complete method for the evaluation of the heat cycle is built up. This model is suitable for the evaluation of cycle performance, and espacially suitable for structurelly configuration real time control soft ware. The method avoids the complete dependence of former fluid network models on the system's structure and difficulties inthe maintenance of soft ware and thus meets the requirement of object orientated and configuration soft ware.
