结合西北电网的实际系统，重点从电网的潮流分布、电网稳定校核、短路电流水平计算3个方面，分析大容量核电机组的接入对西北电网的影响。研究表明：远景西北电网能够适应单机容量为1.75 GW的核电机组，陕西安康、宁夏吴忠核电机组的台数不宜超过1台，甘肃临夏核电机组台数不宜超过3台。

The adaptability of large capacity nuclear power plants after accessing in Northwest grid was analyzed, which focused on problems in terms of power flow distribution, grid stability level and short circuit level. The study result shows that the planned power grid of Northwest can satisfy the need for nuclear power plant with unit capacity of 1.75 GW, but the number of Shaanxi Ankang or Ningxia Wuzhong nuclear power units should not be more than 1 in, the number of Gansu Linxia nuclear power unit should not be more than 3.
