摘要
为降低地铁列车运行能耗,提出了基于惰行控制的节能优化方案。根据地铁列车运营特点和列车运行能耗特性,同时结合列车优化操纵方法,在不考虑列车运行过程中的工况转换时间前提下,提出了一种快速搜索适合惰行点的节能优化算法,并与其他2种惰行优化处理方式进行仿真对比。结果表明:基于惰行控制的节能优化方法能有效地降低列车能耗,算法处理速度快,同时满足高精度的定时运行要求。所提出的节能优化处理方式在节能效果上比逐个处理方式高10.8%,比同时处理方式高4.5%。
To reduce metro vehicle operation energy consumption, energy-saving optimal scheme based on coasting control was studied. According to characteristics of metro vehicle operation and energy consumption characteristics, combined with optimized train handling method, an energy optimization algorithm of quick search for coasting point was presented. Compared with the other two coasting optimization approach by simulation. The results show that coasting energy-saving optimizing control method is effective to reduce train energy consumption, with not only fast processing speed, but also meeting the high-precision timing requirements, and the energy-saving effect is 10.8% higher than the one by one coasting optimization mode, 4.5% higher than the simultaneous mode,.
