综合负荷特性的分类综合方法及其应用

STUDIES ON CLASSIFICATION AND SYNTHESIS OF COMPOSITE DYNAMIC LOADS

针对当前负荷建模研究和工程应用中存在的问题,研究了动态负荷特性分类和综合的问题。分析了感应电动机综合负荷模型参数灵敏度,提出了基于模糊c均值聚类的负荷特性分类方法,其中提出了多种特征量,采用直接综合和加权平均综合两种综合方法对分类结果进行综合建模。现场实测数据建模实例证明了方法的有效性。

Aiming at the existing problems of load modeling and its engineering application, this paper studies classification and synthesis of dynamic loads. The parameter sensitivity of induction motor load model is analyzed. A new approach based on fuzzy c-means clustering is proposed for the classification of dynamic load characteristics. Two synthesis methods, i. e. direct method and weighted averaging method, are compared. The practical application results at Jindai substation of Henan provincial power company validate the methods.
