摘　　要：宜万线因近远期列车对数较少,线路无负荷和轻负荷的概率较大,外部电源薄弱,牵引变电所采用固定补偿将导致功率因数大幅下降,电能质量差。本文结合宜万线的特点,通过分析我国牵引变电所在无功补偿和谐波治理方面采用的各种方案,得出了适合宜万线的牵引变电所无功补偿方案。Since the pair of trains in Yi-Wan line are relatively less in short-term and long-term that will produce higher probability of non-load and light-load and the weaker exterior power, so the adoption of fixed compensation in traction substation will lead to the dramatic decline of power factor and degradation of power quality. Combined with the characteristic of the line, based on the analysis of plans on reactive compensation and harmonic control, it obtains the reactive compensation plan suitable for the traction substations in Yi-Wan line.
