基于DIGSILENT建模的10 kV中压线路供电半径优化研究
|
摘要
从四川省低密度负荷区低电压问题治理现状出发,以《配电网规划设计技术导则》10 kV中压线路的相关规范为基础,采用DIGSILENT软件建模、仿真了10 kV架空线路不同线径,不同负荷量下的末端电压,进而推导求出不同线径型号在不同负荷结构下的合理供电半径。相关研究成果可以作为现有10 kV架空线路供电半径相关标准的细化补充。
Preceeding from the current situation of low voltage problem in low density load area in Sichuan province,and based on the relevant specifications of 10 kV medium-voltage line in " The Guide of Planning and Design of Distribution Network",the modeling and simulation of terminal voltage with different wire diameter and different load capacity of 10 kV overhead lines are carried out with DIGSILENT software,and thus the reasonable power supply radius when hanging different loads is derived. The related research results can be used as a detailed supplement to the existing standards for power supply radius of 10 kV overhead line of State Grid Corporation of China.
