摘　　要：针对某专线电力用户无功电量异常的问题,进行了现场检测,结合输电线路参数进行了无功电量理论分析与计算;探讨了无功电量异常的原因,提出解决措施,并验证了整改效果。对无功计量和无功补偿以及输配电设备设计与选型有一定的参考价值。In order to find out the reason of the abnormal reactive power consumption for a dedicated line, we have carried out the field test, and calculated and analyzed the theoretical reactive power of the line combining with its param- eters. The paper approached the reason of the abnormal reactive power, presented a method to solve the problem, and verified the effectiveness of the rectification. All these will be quite helpful to the reactive power measurement and com- pensation, and also have a certain reference value for the design and selection of power equipment.
