摘　　要：在公变台区线损管理实践中,用户无功功率及损耗对线损的影响常常未能引起人们重视。首先在理论上分析了低压无功电量对台区线损的影响,定量计算对线损造成影响的程度;然后通过引入一个低压用户无功电量对台区线损影响的案例,探索公变台区线损排查方法及对应处置措施,为解决台区线损问题提供了新方向。In the practice of line loss management in common transformer station area,the influence of user reactive power and loss on line loss often fails to attract people′s attention.Firstly,the influence of low-voltage reactive power on the line loss in the substation area is analyzed theoretically,and the degree of influence on the line loss is calculated quantitatively.Then,by introducing a case of the impact of low-voltage user reactive power on the line loss in the station area,the investigation method and corresponding treatment measures of the line loss in the public transformer station area are explored,which provides a new direction for solving the line loss problem in the station area.
