摘要

In this chapter, the low-frequency oscillation mechanism for the CRH5 EMUs accessed in the high-speed railway system is analyzed. Firstly, the time-domain state-space average model of the vehicle-grid system is established. Then, two time-domain stability analysis methods are employed to analyze the stability of the vehicle-grid system.
