摘　　要：电力负荷的模型对电力系统电路仿真结果有着非常重要的作用和影响。本文在对电力系统负荷建模与电力系统负荷模型基础理论、基本模型的求取基础上,为更好的表征负荷模型的特性,提出广义电力负荷实用模型。利用3机10节点系统的PSASP仿真,方案验证表明提出的模型可以较好的反应动态参数,而且参数求取也比较方便,通用性相对于一些其他的模型要强。Power load models play a very important role and have great impact on the simulation results of the corresponding circuit in the power system.In order to better characterize the load model,a practical generalized load model is proposed on the basis of the fundamentals and modeling of the power system.The 3-machine 10-bus system is used for PSASP simulation in this paper.The scheme verification shows that the proposed model can better reflect the dynamic parameters,and the parameters are more convenient to obtain.The generality of the proposed model is stronger than some other models.
