摘要
提出了一种火电厂热力系统通用矩阵模型,该模型基于热力系统的组态结构矩阵,全面考虑了回热加热器换热效率以及各种辅助汽水等因素,以矩阵论为基础,对回热加热器的物质平衡和能量平衡关系进行了分析,通用性很强。该模型适用于不同类型或同类型、不同热力系统的大型火电机组的热经济性分析,为热力系统的实时监测、控制和优化提供了方便的工具。
This paper proposes a general matrix model of thermal power plant thermodynamic system. Based on the configuration structural matrix of thermodynamic system, the proposed model comprehensively considers factors such as the heat exchange efficiency of regenerative heaters and various auxiliary steam and water. With the theory of matrices as the foundation, it analyzes the relationship between material balance and energy balance in regenerative heaters, and has strong versatility. The model is suitable for heat-economy analysis of different-type large thermal generating units or similar units with different thermodynamic systems, thus facilitating the real-time monitoring, control and optimization of thermodynamic system.
