压水堆核电站动力系统简化模型研究与验证

摘要

本文介绍了一套简化的大型压水堆核电站动力系统数学模型，其具有模型简单、建模快捷、易于实现的特点。该模型考虑了反应堆、汽机保护和汽机旁排系统模型，不仅能模拟实现核电站的稳态过程，亦能模拟汽轮机停机、甩负荷等瞬态过程。仿真结果表明，该模型在稳态时具有较高的仿真精度，瞬态过程的主要参数的变化趋势和最终结果与实际情况相符。%An optimized mathematical model for the large NPP power system was described in this report. This model is simplified and easy to build. concerning reactor,turbine protection and turbine bypass system, this model can simulate not only the steady process of nuclear power plant, but also the transient process such as turbine trip and load rejection. The simulation results show that the model has high precision when simulating steady process, and the changing trend and final value of the main parameters are well consistent with the real situation when simulating transient process.
