摘　　要：文章对长距离10 kV贯通线空载及重载供电的情况进行了分析。空载时线路末端电压虽有升高但非常小,对供电影响较小。文章重点对长距离10 kV贯通线重负荷时,末端电压降超过规范规定的现象进行了分析,提出设置串联电容补偿的方案。研究过程中发现存在仅关注末端电压偏差而忽略关注补偿点附近线路电压偏差的问题。通过计算机仿真对该问题进行了分析,提出了解决问题的方法与思路。This paper analyzes the no-load and heavy load power supply of long distance 10 kV run-through electric power line. When no-load,the terminal voltage of the line is increased,but it is very small,which has little influence on the power supply. The article focuses on the analysis of the phen-omenon that the terminal voltage drop exceeds the specifications criterion during heavy load in long distance 10 kV run-through line,and puts forward a scheme for setting up series capacitor compensation. It is found that in the design process designers always pay close attention to the voltage end of the line, but pay no attention to the voltage of the line where mount the series capacitor equipment. At last the problem is analyzed by simulation,and the method and idea of solving the problem are put forward.
