The invention provides a train traction interlocking control system and method. The train traction interlocking control system comprises at least two traction power supply units, a network control system, a traction inverter connected with the traction power supply units and a high-voltage bus connected with the at least two traction power supply units. Each traction power supply unit supplies power to the corresponding high-voltage bus and at least one traction inverter, each traction power supply unit comprises a pantograph, a three-position switch and a high-speed circuit breaker, the three-position switch and the high-speed circuit breaker are arranged in a high-voltage box, the pantograph is connected with the high-voltage bus through the three-position switch, and the high-speed circuit breaker is connected with the high-voltage bus through the high-speed circuit breaker. The pantograph is connected with the traction inverter through a three-position switch and a high-speed circuit breaker which are connected in series; the network control system is connected with the high-voltage box and used for controlling the high-speed circuit breaker in the abnormal traction power supply unit to be disconnected when it is detected that any traction power supply unit is abnormal, interlocking of the train traction power supply unit and the high-speed circuit breaker can be achieved, and fault consequences under multiple faults are reduced.
本发明提供一种列车牵引联锁控制系统及方法,包括:至少两个牵引供电单元、网络控制系统、与牵引供电单元连接的牵引逆变器、以及连接至少两个牵引供电单元的高压母线;每个牵引供电单元向对应的高压母线和至少一个牵引逆变器供电,牵引供电单元包括:受电弓、以及设置在高压箱中的三位置开关和高速断路器,受电弓通过三位置开关与高压母线连接,受电弓通过串联的三位置开关和高速断路器与牵引逆变器连接;网络控制系统与高压箱连接,用于在检测到任一牵引供电单元异常时,控制异常的牵引供电单元内的高速断路器断开,能够实现列车牵引供电单元与高速断路器联锁,降低多重故障下的故障后果。
