Traction Network Resonance Suppression Strategy Based on Auxiliary Filter Winding of Traction Transformer

This paper analyzes the harmonic transmission characteristics of the traction network and the characteristics of the resonance of the traction network through a simplified traction network model, and gives a traction network resonance suppression measure based on the auxiliary filter winding of the train traction transformer. Compared with traditional methods, this method is simpler to implement, lower in cost, and has a good compensation effect. Finally, by building a train-traction network joint simulation model, the correctness of the parameter design of the proposed resonance suppression method and the superiority of the resonance suppression effect are verified.
