【摘要】：以AP1000为代表的第三代核电技术是我国核电发展的重要方向之一。建立了AP1000核电厂动态模型,该模型由反应堆堆芯及冷却系统、冷却剂主泵、蒸汽发生器、汽轮机及其控制系统、发电机等模型组成;基于PSASP/UPI技术实现AP1000核电厂动态模型与电力系统连接,计算核电厂与电力系统之间的动态过程。结果表明,基于上述核电厂模型得到的仿真结果与基于核电厂专用仿真软件PCTRAN得到的仿真结果基本一致,验证了所建立AP1000核电厂模型有效性,该模型具有较高的仿真效率,可用于AP1000核电厂接入电网的稳定计算和分析;在电力系统中长期稳定分析中,应该考虑核电厂主蒸汽压力变化对汽轮机机械功率输出的影响,为AP1000核电厂接入电网的稳定分析奠定了基础。
[Abstract]:The third generation nuclear power technology represented by AP1000 is one of the important directions of nuclear power development in China. The dynamic model of AP1000 nuclear power plant is established. The model consists of reactor core and cooling system, coolant main pump, steam generator, steam turbine and its control system, generator and so on. The dynamic model of AP1000 nuclear power plant is connected with power system based on PSASP / UPI technology, and the dynamic process between power system and nuclear power plant is calculated. The results show that the simulation results based on the above model are basically consistent with those based on PCTRAN, which verify the validity of the AP1000 nuclear power plant model, and the simulation efficiency of the model is high. It can be used to calculate and analyze the stability of AP1000 nuclear power plant connected to the power network, and in the medium and long term stability analysis of power system, the influence of the variation of the main steam pressure of the power plant on the power output of steam turbine should be considered. It lays a foundation for stability analysis of AP1000 nuclear power plant connected to power grid.
