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。The third generation of nuclear power generation technology represented by AP1000 is one of the important development directions of nuclear power industry in China. A dynamic model of AP1000 nuclear power plant, which is composed of such models as reactor core and its coolant system, main pump for coolant material, steam generator, steam turbine and its speed control system and generators, is built. Based on PSASP/UPI technology, the connection of the built dynamic model with power grid is implemented to calculate the dynamic processes between nuclear plant and power grid. Simulation results obtained by above-mentioned nuclear power plant model is basically the same those by special simulation software for nuclear power plant PCTRAN, thus the effectiveness of the built dynamic model of AP1000 nuclear power plant is validated. The built model possesses higher simulation efficiency, so it can be used to calculate and analyze the stability of power grid connected with AP1000 nuclear power plant. In medium-and long-term stability analysis, the impact of main steam pressure variation in nuclear power plant on mechanical power output of steam turbine should be taken into account to lay the foundation for stability analysis of power grid connected with AP1000 nuclear power plant.
