The invention discloses an OLTC-based full-time stability optimization method for a railway vehicle network system, and the method specifically comprises the steps: collecting data for planning the railway vehicle network system, then dividing a train operation diagram into a plurality of time points, and determining the positions, number, operation power and operation conditions of vehicles in the system at each designated time point; based on a multi-vehicle common network system stability analysis method, vehicle network system stability at all time points is analyzed in sequence; based on the stability analysis result of the multi-vehicle common network system, adjusting the position of an OLTC tap, and re-evaluating the stability of the vehicle network system until all the vehicle network systems meet the stability margin requirement at all moments; the test is carried out on the hardware-in-the-loop platform to evaluate the stability of the railway vehicle network system. The algorithm is simple, the cost is low, and the system stability is improved.
本发明公开了一种基于OLTC的铁路车网系统全时段稳定性优化方法,具体为:收集规划铁路车网系统的数据,然后,将行车运行图划分为多个时间点,在每个指定的时间点,确定系统中车辆的位置、数量、运行功率和运行工况;基于多车共网系统稳定性分析方法,依次分析全部时间点下的车网系统稳定性;基于多车共网系统稳定性分析结果,调节OLTC分接头位置,并重新评估的车网系统稳定性,直到所有车网系统在所有时刻下都满足稳定裕度要求;在硬件在环平台上进行试验以评估铁路车网系统稳定性。本发明的算法简单、成本低,且提高了系统稳定性。
