摘要(Abstract)：

核电机组具有单机容量大、核安全要求高,且对电网扰动敏感等特征。以大型压水堆核电机组为研究对象。建立了压水堆模型,利用时域仿真法及暂态能量函数法研究了核电接入电网的暂态稳定性,以三门核电机组接入浙江电网的枯水季节最大运行方式作了算例分析。仿真计算了电网短路故障和N-2故障类型扰动下的系统及核电机组的暂态稳定性。结果表明,三门核电机组能承受电网的一般故障且接入对电网暂态稳定的影响很小,电网具有较强的稳定性。
Nuclear power units are characterized by large unit capacity, high nuclear safety requirements, sensitivity to grid disturbance and so on. In this paper, the study subject is large pressurized water reactor nuclear power plants. The model of the pressurized water reactor is established, and the transient stability of the nuclear power connected to the grid is studied using time-domain simulation method and transient energy function method. The paper analyzes maximum operating mode in dry season of Sanmen Nuclear Power Plant when connected to Zhejiang power grid. The simulation calculates the transient stability of the system and the nuclear power units suffering multiple types of fault disturbances such as grid short-circuit fault and N-2 fault. The result shows that Sanmen Nuclear Power Plant can withstand common faults and has little influence on the transient stability of power grid. This system is strongly stable.
