| 摘 要： | 以某地区的多条220 kV母线为研究对象,针对母线数量众多,负荷类型多样的特点,采用模糊C均值聚类的方法将母线进行初步分类。再选取每个类别的典型母线,分别从母线的负荷特性指标、负荷曲线特点、与气象因素以及日类型的关系等方面进行深入的研究和分析,总结出每个类型母线的重要影响因子和在不同日类型下负荷曲线的变化趋势,为下一步开展母线负荷预测工作提供服务,进而提高地区母线负荷预测的工作效率和预测精度。

| Abstract: | This paper focuses on the research of 220 kV bus load characteristics in a particular area where the bus bars are numerous and the load characteristics are different from each other,and categorizes them into different kinds by using fuzzy C-clustering method.Then the paper selects typical bus bar from each category,through the research and analysis on the bus load characteristics,load curve,meteorological factors and type of day separately,summaries the important influence factors of each type of the bus bar and the change trend of the load curve with different day types,in order to improve the work efficiency and accuracy of regional bus load forecasting. |
