| 摘 要： | 电力系统负荷模型的准确性对电力系统的分析与控制起着重要的作用。人工神经元网络模型能较好地模拟实际负荷的动态特性，但其模拟的精度很大程度上取决于输入量的选取。本文选取三组不同的输入量，采用误差反向传播算法（ＢＰ算法）进行训练．并对其精度作了比较，从而提出用人工神经元网络估计负荷模型时所应选取的输入量。

| Abstract: | Accurate load models play an important role for power system analysis and control.Artificial neural networks(ANN) Can map the dynamic characteristics of actual loads better.But the precision of the load models depends greasy on the selection of the input variables of the ANN.Based on back propagation(BP) training algorithms, three different groups of input variables are selected, and their resultS are compared.Then, the input variables that should be selected in the estimation of load models vsing ANN have be presented in this paper. |
