Zusammenfassung:A traction network high harmonic suppression method and system, and a rail transit vehicle. The method comprises: collecting a network voltage of a contact network in real time, and calculating the harmonic content and the characteristic frequency of the network voltage; if the harmonic content is not less than a preset threshold value, determining that the network voltage is abnormal, and controlling a four-quadrant converter to stop running; and determining whether the characteristic frequency of the current network voltage is within a preset range of the characteristic frequency of a certain four-quadrant control mode, and if not, controlling the four-quadrant converter to run in the four-quadrant control mode.
