配电网接入客户容量与配出容量的关系推导

Derivation of relationship between customer input capacity and output capacity in distribution power network

随机抽取长沙城区2007年40条10 kV线路和30座变电站的运行数据为样本,用回归分析法进行推导,得出10 kV配电线路配出容量与接入配电变压器容量的相关关系经验公式以及变电所最大配出负荷与接入配电变压器总容量的相关关系经验公式,为城市电网规划设计工作提供一种计算方式。

Operation data from forty 10kV Power lines and thirty substations in Changsha in 2007 were randomly selected as samples and were deduced by regression analysis. Related empirical formula between input transformer capacity and output capacity of 10kV distribution lines and Related empirical formula between substation maxim output load and input distribution transformer total capacity were obtained, offering a calculation mode for urban power network planning and design.
