农村中压配电网供电模型研究

Rural Power Supply Model of Medium Voltage Distribution System

目前,国内对农村网架结构的研究主要集中在接线模式,不能体现农村不同区域属性条件下变电站的供电结构问题。借鉴国内外城市配电网典型供电模型的设计经验,提出了农村中压配电网典型供电模型的构建方法。在对农网供电模型进行定义并分析其构建影响因素的基础上,采用分区加权Voronoi图对农网供电区域进行划分,实现农网的分区供电;采用最小生成树(MST)生成农村中压配电网的供电架构和结合接线模式,构建适合农村地区的、系列化、差异化供电模型。通过对农网供电模型扩展的进一步研究,为农村电网建设与配电网改造提供支撑。

Rural Power Supply Model（RPSM）of MV distribution system existed some problems that current researches only focus on feeder connection mode so as to neglect substation structure in different rural areas.The paper learns from typical urban power supply model and proposes the construction method of RPSM.On the basis of that the RPSM is defined and the factors that affecting RPSM are analyzed,using the divisional weighted Voronoi diagram for rural power supply area to achieve partition supply,using minimum-cost spanning tree to generate rural MV distribution grid power structure,and combining with connection mode,constructing a series,differentiation power model which is suitable for rural areas.The further study of RPSM is extended to provide support for the rural power grid construction and transformation of the distribution network.
