电网负荷模型的选择影响着其仿真计算的准确性，采用乐观的负荷模型可能对电网安全造成不利影响。针对近期南方电网发生的三次扰动事件，选择电力系统规划运行中常用的静态、电动机加恒阻抗、综合负荷模型进行故障拟合，分别从短路电流、有功功率振荡及电压波动等进行比较分析，总结了各负荷模型在现阶段南方电网仿真计算中的适用性。

The load model selection of a power system affects the accuracy of its simulation, and it is possible to endanger its safe op-eration with an optimistic load model. According to three disturbance events occurred recently in China Southern Power Grid ( CSG) , fault simulations are carried out with three kinds of load model, including the static load model, motor with constant impedance load model, and synthesis load model. This paper gives a comparative analysis in terms of the short circuit current, active power oscilla-tion, and voltage fluctuation, and summaries the applicability of each load model for CSG in the present simulation.
