【摘要】 提出了一个适于计算机软件开发的电站热力系统通用矩阵模型,并编制了程序,通过实例计算验证了模型的正确性。该模型基于热力系统的结构特征矩阵和回热加热器的“通断系数”,对加热器的结构特征进行了高度的抽象,全面考虑了回热加热器类型、换热器效率以及各种辅助汽水等因素。该矩阵模型结合了组态思想,算法可靠,通用性强,适用于大型火电机组的热经济性分析计算,为电厂实时监测和分析软件的开发提供了方便的工具。更多还原

【Abstract】 This paper presents a general matrix model of thermodynamic system of thermal power plants, which is applicable for computer software development. The model was considered with the configuration method. The types and structures of the regenerative heater were highly abstracted. Based on the system’s configuration character matrix and the switching variables of the heaters, many factors were taken into account thoroughly, such as the type of regenerative heaters, efficiency of heat exchangers and assistant steam and waters. An example has been calculated to validate this model. The model and can be applied to the thermoeconomical analysis of real-time monitoring software in thermal power plants.更多还原
