本文分析了目前电气化铁路牵引供电系统网络能耗问题,提出了减少能耗的改进方案,可达节省能耗20～34％;同时显著改善网压水平与提高供电的可靠性,从而将收到更大的经济效益。通过分析与计算论证,建议今后进行单线铁路电气化时,实施与推广“单相牵引变电所与链形并联供电式系统”。它在改善对电力系统的不对称度影响与减小对弱电线路的干扰影响等方面也都将是有所助益的。
In this paper, the energy consumption of traction power supply system in electrified railway is analyzed, and an improved scheme to reduce energy consumption is proposed, which can save energy consumption by 20% to 34%. At the same time, the net voltage level is significantly improved and the reliability of power supply is improved. Greater economic benefits. Through the analysis and calculation and demonstration, it is suggested that to implement and popularize “single-phase traction substation and chain parallel power supply system” in the future when electrifying single-track railway. It will also be helpful in improving the impact of asymmetry in the power system and reducing the effects of interference on weak lines.
