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。图７参６
This paper proposes a new mathematic model of thermal system in power station --- cycle combination method. This method is based on the balance of quality and heat balance, and is based on the heat recovery sub-cycle formed by the basic level group and the corresponding heater to form a complete set of thermal system accounting method. The model is suitable for system performance calculation, especially suitable for the configuration of real-time monitoring software. This method avoids the problems that the former fluid network model is completely dependent on the system structure and poor software maintenance performance and meets the requirements of object-oriented components and configuration software.
