| 摘 要： | 农网线路中并联动态补偿电容器不仅可以减少线路上的有功损耗、提高功率因数,而且可以改善线路上各节点的电压水平。无功补偿的降损效果与电容器的投切方式密切相关。目前国内两种主要投切方式是按功率因数和按电压,它们对应着不同的布点方法。比较两种布点方法的无功潮流,并对线路的降损效果做了理论分析。结果表明,在配电线路中采用按电压投切方式,更有利于降低线损和提高线路末端电压。

| Abstract: | The dynamic compensation in distribution line can not only reduce the active power loss of certain lines and improve power factor,but also improve each nodal voltage level.Loss Reduction of reactive power compensation is closely related to capacitor switching on off manners.At present,two main switching on off manners are based on power factor and voltage,which correspond to different distribution methods,this paper compares reactive power flow under the two methods,and analysis the effect of reducing losse... |
