Ground automatic neutral section passing technology has become an effective method to improve speed, the transportation efficiency and capacity of high-speed and heavy-haul railway, and the control strategy adopted by trains is the key to give full play to the advantage of ground automatic neutral section passing technology. Based on the analysis of the control process and problems of mechanical switch ground automatic neutral section passing for trains, a train control strategy with better matching and adaptability was proposed. The power loss detection algorithm of four-quadrant converter, DC voltage control of inverters, overall control logic and protection were expounded. The validity of the control strategy was verified by the adaptability test of the electronic switch neutral section passing for electric locomotive, which realized the electrified neutral section passing for the train and the continuous power supply for the auxiliary system, nearly without losing the traction and speed, and without perceiving for neutral section passing in section post.
