摘　　要：高铁在我国已经较为普及,而高铁牵引站的供电方式相对特殊,其计量接线错误分析对比三相负荷平衡系统有明显差异。为掌握其差异性,针对高铁牵引站其中一相作为公共相运行及输电线路换相的特点,对昌赣高铁某牵引站实际案例中的计量回路错误接线进行相量图分析,后排查出Ub、Uc反接造成供、受两侧计量电量相差巨大。经纠正后,共追补错误接线期间电费损失756 756元,为电力行业计量专业在高铁牵引站电量追补方面提供借鉴与参考,具有普适意义。High⁃speed rail has become popular in China,but the power supply mode of the high⁃speed rail traction station is spe⁃cial,and its measurement and wiring error analysis and compari⁃son of the three⁃phase load balancing system are obviously differ⁃ent.In order to grasp the difference,according to the characteris⁃tics of one phase of the high⁃speed railway traction station operat⁃ing as a public phase and commutation of the transmission line,a phasor diagram analysis of the incorrect wiring of the metering cir⁃cuit in a real case of a traction station of the Changgan high⁃speed railway is carried out,and the Ub,Uc reverse connection results in a huge difference between the power supply and the metered power on both sides.After correction,a total of 756,756 yuan of electrici⁃ty loss during the wrong wiring period is compensated,which pro⁃vides reference and reference for the electric power industry meter⁃ing profession in the recovery of electricity at high⁃speed rail traction stations,which has universal significance.
