Multi-train modeling and simulation integrated with traction power supply solver using simplified Newton–Raphson method

摘要: Multi-train modeling and simulation plays a vital role in railway electrification during operation planning phase. Study of peak power demand energy consumed by each traction substation needs to be determined verify that electrical flowing its feeding system is appropriate or not. Gauss–Seidel, conventional Newton–Raphson, current injection methods are well-known widely accepted as tool for network solver DC supply study. In this paper, simplified Newton–Raphson method has been proposed. The proposed employs set current-balance equations at node instead the power-balance equation used method. This concept can remarkably reduce execution time computing complexity multi-train simulation. To evaluate use, Sukhumvit line Bangkok transit (BTS) Thailand with 21.6-km length 22 passenger stopping stations test system. integrated developed simulate 1-h service selected 5-min headway. From obtained results, more efficient approximately 18 % faster than just over 6
