Due to the voltage low-frequency oscillation (LFO) of high-speed railway traction network and Electric Multiple Units (EMUs) coupling system, many EMUs in different EMU depots appear the traction blockade. First, the mathematical model and small-signal analysis model of EMUs-traction network cascade system (ETNCS) are built. Second, considering Auto-transformer (AT) leakage reactance, traction network...
