摘要
根据机车供电特性、牵引机车类型、变电所各条馈线上列车运行状况以及各条馈线坡道状况,通过理论分析计算,算出一天只投一次的情况下获得的最大功率因数及投切时间,过补和欠补的状况基本得到解决,同时设计了两种算法计算馈线电流,使得铁路供电段的电能利用率有较大幅度的提高.
We have worked-out the biggest power factor and delivering-cut time, based on theoretical analysis and calculation, of each traction transformer station in accordance with the special requirements of engine power supply, types of traction engine, the railway operation condition of each feeder line of transformer station and the slope condition of each feeder line. The case of over-mend and owing-mend has been basically solved and two algorithms for calculation feeder current are designed, According to the research, the utilization rate of electric energy for the railway electricity supply section can be drastically increased.
