居民负荷特征研究及特征库的建立

Research on Features of Residents' Loads and Establishment of Feature Library

居民用户用电可视化是开展节能工作的基础。在居民用户用电可视化研究中,了解居民用户侧典型家电的负荷特征和耗电特性是关键。通过分析各种类型的负荷特征,从中选取一些具有较高辨识性的特征量作为负荷特征库的主要内容。构建电力数据采集平台,采集典型的家电负荷用电数据,并根据一定的数学方法提取各负荷特征,形成负荷特征库。利用Matlab构建负荷特征库可视化界面,方便调用和分析负荷特征,为后续负荷识别奠定基础。

The visualization of consumer electricity is the basis of energy-saving work. It is the key to understand the load characteristics and power consumption characteristics of typical household electrical appliances on the user s side in the study of the residents electricity consumption visualization. By analyzing various types of load characteristics, some characteristic quantities with higher identification are selected as the main contents of load feature library. Through the construction of power data acquisition platform, the typical household appliance power consumption data is collected. Then the load characteristics are extracted by a certain mathematical method and load feature library is formed. Finally, a visual interface of load feature library is constructed to facilitate the invocation,analysis of load characteristics and it lays a foundation for subsequent load identification.
