Status and Development of Neutral Section Passing Technology for Electrified Railway Trains
Structure of the electrified railway traction power supply system and the influence of the existence of the electrical phase separation zone on the traction power supply system were introduced. By discussing the development status and existing problems of automatic neutral section passing technology and three kinds of ground automatic neutral section passing technologies all over the world, a comparative analysis of the advantages and disadvantages of various programs was put forward, and the merits of each scheme was pointed out. A virtual in-phase flexible power supply system scheme was proposed, which solved the problems of neutral section passing and power quality at the same time, providing a new idea for the development of electrified railway.
