Neutral Section

Over-voltages happen when electric locomotive passes the neutral section, which has serious influence on safe operation of the traction power supply system. This paper builds the model of contact net and neutral section of traction power line and analyzes transient process of the electric locomotive passing the neutral section. This paper proposes automatic control system for electric locomotive passing neutral section. It is effective to avoid the over-voltages.
