| 摘 要： | 近年来,由于城市改造杆线入地,由架空线改为地下电缆,产生了大量的充电电压,电网电压结构发生变化,而大量的充电电压必须通过停、投电抗器才能达到合格电压标准,这样使得电网的无功管理变得更加复杂。根据合肥电网运行工况,在实验测试的基础上,分析了多电缆出线对城市电网电能质量的影响因素,并提出了改进措施。

| Abstract: | In recent years,a large number of charging voltage has been generated since the utilization of electric cable in cities instead of overhead line,which also changes the structure of power system.In order to maintain the voltage standard,the inductor is applied in the power grid,which makes the management of power grid more complicated.In this paper,according to the operating situations of power grid in Hefei,the influence of multi-loop cable outlets on the power quality of urban power grid is analyzed based on the experimental results,and the countermeasures are also put forward. |
