摘　　要：针对负荷模型应用的薄弱环节，探讨了负荷模型的应用接口问题。内容包括：仿真计算中的负荷模型的处理；在ＢＰＡ中加入差分方程的负荷模型的方法；不同时步模型的转化；系统故障或操作后的跃变量计算中新的负荷模型的处理。文章最后给出的例子说明了负荷模型加入的正确性。The application of electric load models in power system simulation has not been well studied. To overcome this weakness, in this paper an application interface of load model is analyzed. After describing the load models used in current power system analysis software packages, a method of adding differential equation load model to BPA is put forward and the load model translation of different time steps is studied. It is also studied that how to use this new load model in the calculation of sudden changed variables which appear after fault or operation of power system. The result of a test example indicates that the adding of load model is correct.
