摘　　要：研究了负荷模型对电力系统仿真计算的影响。从暂态稳定、电压稳定等多个角度出发,结合内蒙电网等实际算例并采用BPA程序进行仿真,综合分析各种负荷模型可能对电力系统仿真结果造成的影响。结果表明,负荷模型对仿真结果的影响与负荷所处的位置、网架结构、电源分布等因素密切相关,所得结论揭示了负荷模型对电网仿真计算的重要性,有助于提高电网仿真的精度。This paper studies the influence of load model on power system simulation is investigated in this paper.For the sake of the transient stability,voltage stability,etc.the practical example of Inner Mongolia power grid is simulated by BPA,and the influence of various load models on power system simulation result is studied.On the basis of practical examples,it can be asserted that the effect of load modeling is closely related to the place,structure of power grid and power distribution.The results indicate that the importance of load models for power system simulation,which is beneficial to enhance the power system simulation accuracy.
