The Sichuan-Tibet railway contains long ramp. To ensure the uninterrupted power supply of the locomotives on the long ramp, the number of phase breaks is reduced. However, this will result that multiple locomotives operate together under the same power supply section and may further create unexpected low-frequency oscillation (LFO) in the Locomotive-network (L-N) system. Previous researches have established the L-N system model and analyzed the mechanism of LFO, but lacked the evaluation of the maximum operable locomotive number under the traction network. In this paper, according to the traction power supply mode and the locomotive in the Sichuan-Tibet railway, the maximum operable locomotive number to ensure the system stability is analyzed. It is found that under the same network-side parameters, the maximum operable locomotive numbers of the freight locomotives are higher than passenger locomotives. Finally, the simulation results validate the correctness of the theoretical results.
