摘　　要：10 kV中压电力线作为配网负荷输送的核心线路,负载平衡分配可很大程度的降低线损。然而电网现状是10 kV线路基础信息紊乱、线变关系模糊,致使负荷不平衡导致线损率高。目前解决方法是人工巡线、拉电判别等传统方式,时效性差、准确率低,同时潜在人员伤害的风险。文中讨论一种基于中压载波通讯装置的负荷切改智能感知系统,利用10 kV中压线路的唯一物理线路传输特征序列信号,实时的准确的判别线变关系,并对负荷切改智能感知,使10 kV中压电力线处于最优的负荷分配,降低线损,可有效降低电能能量的损耗。As the core line of distribution network load transmission, 10 kV medium voltage power line can reduce line loss to a great extent. However, the current situation of the power grid is that the basic information of 10 kV line is disordered and the relationship between line changes is fuzzy, which leads to unbalanced load and high line loss rate. At present, the solution is the traditional way such as manual line inspection and power drawing discrimination, which has poor timeliness, low accuracy and the risk of potential personnel injury. In this paper, we discuss a middle carrier communication device based on the load change intelligence told system, using the only physical line 10 kv medium voltage line sequence signal transmission characteristics, real-time accurate criterion line change relations, and the load change intellisense, make 10 kv medium voltage power line is in the optimal load distribution, reduce the line loss, greatly reduce the wastage of the electricity energy.
