摘　　要：文献[1]中提出了负荷特性在线测辨的新思路:先根据在线采集的数据辨识得到动态模型,然后再由动态模型获取静态特性参数。文[1]中辨识得到的是离散的动态模型,而电力系统实际应用中可能需要其它形式的模型.本文将给出各种形式模型之问的转换关系,并给出由负荷的动态模型获取静态特性系数的很简单的公式。文中给出了算例,验证了上述思路和方法的可行性。In reference [1], a novel principle is proposed for the on-line identification of load characteristics, i.e. identifying the dynamic model with the on-line measured data, and then determine the static coefficients according to the dynamic model. The discrete models developed in reference [1] should be transformed into the models in the form applied in power systems. The transformation relations between the models in different forms are given, and the formulas for determination of static coefficients are derived. The formulas are illustrated by an example.
