摘要
采用10kV线路补偿装置进行无功功率补偿,提升电能质量时,该线路补偿装置的补偿容量需进行匹配。若容量设计过大,则易导致当10kV配电网中负荷较小时,导致线路补偿装置过补偿,线路损耗增加、恶化线路传输容量与效率,进一步降低电压质量。若补偿容量设计过小时,则补偿效果不足,电能质量虽然得到了提升,但是效果不佳。因此需计算线路补偿装置的补偿容量。分析了线路补偿装置容量与安装节点的计算迭代优化方法,并进行了实验论证。结果表明,该方法能够提升电能质量。
A 10kV line compensation device is used for reactive power compensation.When the power quality is improved,the compensation capacity of the line compensation device needs to be matched.If the capacity design is too large,it will easily lead to overcompensation of line compensation device when the load in 10kV distribution network is relatively small,resulting in increased line loss,further deterioration of line transmission capacity and efficiency,and further reduction of voltage quality.If the compensation capacity is too small,the compensation effect is insufficient.Although the power quality is improved,the effect is not good.Therefore,the compensation capacity of line compensation device needs to be calculated.This paper analyzes the computational iterative optimization method of the capacity of the line compensation device and the installation node,and carries out experimental demonstration.The results show that this method can improve the power quality.
