牵引变电所采用220kV进线的优越性

Advantages of adopting 220 kV feed lines in traction substations

通过简化分析计算表明 ,牵引变电所采用 2 2 0 k V进线将使电压总谐波畸变率、三相电压不平衡度和电压波动降低 .建议设计部门在合适条件下考虑在实际工程中采用。

By simplified analyses, it is revealed that supplying traction substation by 220 kV feed lines can decrease total harmonic distortion, degree of unbalance and fluctuation of voltage. The design departments are recommended to adopt 220 kV feed lines in actual engineerings under proper conditions.
