Abstract
In a DC-fed motor drive system that implements a regenerative braking control strategy, the oscillation phenomenon in electrical system occurs due to the regenerative power regulating to prevent a DC-link over-voltage condition. In this paper the oscillation phenomenon of electrical system in the PMSM drive of railway vehicle system with a light-load regenerative braking control is pointed out. First, a simulation is carried out to confirm the oscillation phenomenon occurrence. The investigated model is then derived and its stability analysis is elucidated. Base on the analysis results a novel anti-oscillation strategy is proposed. A downsized experimental system is used for validation purpose. It is verified that the proposed strategy eliminates the oscillation effectively.
