摘要
该文针对压水堆核电机组二回路再热系统的特点,将循环函数法加热单元的划分原理进行推广,划分出二回路热力系统主循环、再热蒸汽循环以及其他循环,从而推导出一套便于理解、计算简捷的二回路系统热力计算数学模型。在此基础上得到整个二回路热力系统的 “系统凝汽系数”,可以方便地用来分析二回路系统的热经济性。通过实例计算,验证了所提数学模型的准确性和通用性。
According to the characteristics of the reheat system of the secondary circuit of pressurized-water reactor nuclear power plant, the main cycle, reheat steam cycle and other cycles of thermal system of secondary circuit are proposed with extending the theory of the cyclical function method. In this paper, a mathematical model for economic analysis is proposed. On the above basis said, the system exhaust coefficient is given which reveal the thermal-economy of the secondary circuit expediently. The correctness of the proposed analytical method is proved by calculations of some examples.
