Research on load characteristics of urban ordinary residential housing and principle of power supply facilities configuration

In view of the wide configuration range of the capacity of distribution transformer in residential districts, and the lack of actual data and accurate design basis, the load characteristics of urban ordinary residential housing and principle of power supply facilities configuration are researched. Firstly, the type of the residential district investigated is decided, 4117 households of three residential districts are selected as research object, large-scale and real-time load sample data which is up to three years is collected by using the smart meters. Secondly, the typical residential load characteristics are obtained by analyzing and summarizing the data collected. In the end, the load characteristics obtained are further analyzed and calculated to configure the power supply facilities of the planning residential district.
