在电力系统仿真计算中,综合负荷模型的感应电动机和恒定阴抗的比例对仿真结果有着十分重要的影响。基于统计综合法负荷建模的思路,对湖南电网负荷特性进行了全面详细的调查统计,在负荷特性调查数据的基础上,利用综合处理的方法得出了湖南电网48个220kV变电站3种不同运行方式的感应电动机负荷和恒定甩抗负荷的实际比例,该结论对于电力系统的仿真计算具有十分重要的意义。总结出的基于实际电网的统计综合调研方法对其他电网的建模工作具有推广应用和指导借鉴的意义。

In the electrical power system simulation computation, the synthesis load model of induction motor and the constant impedance proportion has the important influence on the simulation result extremely. Based on the idea of statistical synthesis load modeling, the paper carried on the detail investigation statistics of Hunan Power Network load characteristics. The actual proportions of induction motor load and the constant impedance load of 48 substations 220 kV under 3 different operation conditions in Hunan Power Network were obtained, using the synthesis processing method and based on the load characteristic investigation. The conclusion has the vital significance for the electrical power system simulation computation. The statistical synthesis investigation method based on the actual power system has the instructive significance for load modeling work of other power networks.
