10 kV配电网网架改造实例分析

Case Analysis of the Grid Renovation of the 10 kV Distribution Network

配电网直接面对终端用户,是保障电力能源“落得下、配得出、用得上”的关键环节,但部分配电网网架结构的不合理直接影响到供电可靠性。以重庆市南滨路具体的网架改造工程为例,从重庆市配电网网架现状分析入手,进一步阐述标准目标网架的构成及南滨路网架逐步向标准化网架改造的实施过程。结果证明,由于重庆市以山地为主、多条河流贯穿的特殊地理环境,宜将以建设单环网为主的标准化供电网格作为未来配电网网架的发展方向。

Distribution networks directly face terminal users,which play an important role in the distribution,absorption and utilization of electric power.However,grid structures of some distribution networks are not reasonable and influence the reliability of power supply.Taking the grid renovation project at Nanbin Road of Chongqing as an example,based on the analysis of the current situation of the grid of the distribution network in Chongqing,this paper expounds the constitution of the standard target grid as well as the implementing process of the standardized grid renovation of the grid at Nanbin Road.The results show that the single-loop grid should be mainly constructed as the standardized power grid due to the special geographic environment of Chongqing featured by mountains and rivers.
