面向10 kV公用台变重载问题的配网设计方案

Distribution Network Design Scheme for Heavy Load of 10 kV Public Transformer

近年来我国居民用电量不断上涨,配网运行负荷逐年上升,部分甚至出现重载或过载情况,严重影响了配网运行的安全性、可靠性和稳定性。文章从某地区10 kV配网运行现状出发,研究面向10 kV公用台变重载问题的配网设计方案,确定变配电设施、架空线路及电缆线路施工技术要点及注意事项,望在一定程度上缓解配电压力,解决公用台变重载问题。

In recent years,the power consumption of residents in China has been increasing,and the load of distribution network has been increasing year by year.Heavy load or overload has occurred in some areas,which has seriously af‐fected the safety,reliability and stability of distribution network operation.Based on the current situation of 10 kV distri‐bution network operation in a certain area,this paper studies the distribution network design scheme for the heavy load problem of 10 kV public transformer,and determines the technical points and precautions for the construction of power transformation and distribution facilities,overhead lines and cable lines.The purpose is to relieve the distribution pres‐sure to a certain extent and solve the heavy load problem of public transformer.
