摘要
在电力传输中,长线路往往会出现负载分散、供电半径过长以及线路损耗较大的问题,而通过安装并联电容器实现无功补偿则可以起到提升电网长线路的功率因数以及线路末端电压的效果.本文即通过案例分析的方式,首先就无功补偿的原理及意义、方式进行论述,然后选择一10 kV长线路就并联电容器无功补偿的应用进行详细论述,最后就无功补偿应用的效果进行了阐述.
In power transportation,long lines often have problems of load dispersion,long power supply radius and large line loss.However,by installing parallel capacitors to achieve reactive power compensation,it can improve the power factor and line of the long line of the power grid.The effect of the terminal voltage.This paper discusses the principle,meaning and mode of reactive power compensation by means of case analysis.Then,the application of a 10 kV long line on the reactive power compensation of shunt capacitors is discussed in detail.Finally,the application effect of reactive power compensation is applied.Explain for reference.
