| 中文摘要: |
| 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756756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。 |
| 英文摘要: |
| High-speed rail has become popular in China, but the power supply mode of the high-speed rail traction station is special, and its measurement and wiring error analysis and comparison of the three-phase load balancing system are obviously different. In order to grasp the difference, according to the characteristics of one phase of the high-speed railway traction station operating as a public phase and commutation of the transmission line, a phasor diagram analysis of the incorrect wiring of the metering circuit 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 electricity loss during the wrong wiring period is compensated, which provides reference and reference for the electric power industry metering profession in the recovery of electricity at high-speed rail traction stations, which has universal significance. |
