摘　　要：针对目前负荷动特性建模中存在的问题，提出了负荷建模必须面向综合的观点，给出了综合的方法，并结合１９９６年沧州地区现场实测数据分析了负荷组成时变系统中综合的可行性和有效性。建模实践表明：负荷动特性综合对于解决目前负荷动特性建模中存在的问题，建立适用于仿真计算的负荷模型有着非常重要的作用。An appropriately accurate representation of load is necessary for power system stability and dynamic analysis. But because of the complex characteristics of load, it is not practical to develop the detailed load model for every recorded load data. This paper gives an idea on the synthesis of dynamic loads and its method. Data from field are used to train synthesis models. The results verify that synthesis-based load modeling can surmount the difficulties such as the variation of load characteristics due to daily, seasonal, weather and other changes. The identified load models can emulate different dynamics well and should be more suitable as a representation of load for stability analysis.
