摘　　要：由于电力负荷具有的时变性、随机性、多样性等特点,使得负荷模型建模成为电力系统几个最困难的研究领域之一,四川电网在2009年开展了负荷建模的理论与实践工作。介绍了德阳五里堆站动态负荷建模平台,应用该平台的测量数据对德阳站进行综合负荷模型辨识,所辨识的实测参数与常规参数进行对比,说明实测负荷模型的精度比典型负荷模型的精度高。Load modeling has been one of the most difficult problems in power system because of its time-variant and stochastic characteristics.The theoretical researches and some practical work were carried out in Sichuan power grid in 2009.The dynamic load modeling platform in Wulidui Substation of Deyang is firstly introduced,then,the field measurement data recorded in this substation are utilized to build the load models.The comparison between the simulation results using the measurement-based load model and the traditional load model indicates the efficiency of the method.
