摘　　要：以300MW火电机组热力系统为研究对象,根据系统特点,在循环函数的基础上结合等效焓降方法,采用模块化建模思想,建立了火电机组热经济性分析的实时模型。经过实例验证:该模型不仅很好地运用于机组热经济性实时分析,而且对于机组改造和设计的定性分析具有一定的指导意义。Regards the thermal system of 300MW unit as research object, according to the system charac- ter, combines equivalent enthalpy drop method based on cycle function, adopts the thought of module modeling, the real- time model of heat economic analysis is built. The result proves that, this model is not only useful for the real - time analysis of heat economic, but also useful for the qualitative analysis of reform and design of the power plant unit.
