Abstract

In recent years, there have been a number of low-frequency oscillations (LFO) of electric multiple units and traction network coupling system (EMUs-TNCS) in high-speed railways, leading to traction blockade of the EMUs. Taking the CRH5 EMUs as an example, this paper presents a double closed-loop control strategy for EMUs PWM rectifiers based on current passivity-based control of sliding mode structure (CPBC-SMS) to suppress the LFO. Firstly, a return-ratio matrix model of the EMUs-TNCS is established, and the generation mechanism of the LFO is analyzed by using the G-sum norm criterion, obtaining the critical condition of the LFO. Then, according to operating conditions of the LFO, the state space model of each EMUs rectifier is derived in dq-frame. Subsequently, the internal loop current controller based on CPBC-SMS is designed. Stability analysis and simulation results validate that the proposed control provides effective capability of the LFO suppression with better steady-state and dynamic performance compared to several conventional methods.
