摘要
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 operation 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.
