逐步多元回归法在负荷模型扩展中的应用
Application of Stepwise Multiple Regression to Load Model Extension
摘要
Abstract
In order to derive a load model with the only known condition of load composition, the multiple regression method was applied to the extension of the model. First, the model regression function was investigated according to the obtained information about load models and load composition.Then, the model at the point without field measurements was deduced based on its load composition and the model regression function. The stepwise method, which overcomes the disadvantages of the forward method and the backward method, was adopted in the selection of variables for the build of model regression function. Thus the model built up by the stepwise method can be more practical than the one derived by the basic vector method, since the latter requires more load model information. It is concluded that the proposed method provides guidance for load model application, and is proved to be effective by the actual instance.关键词
