The invention provides an intelligent three-phase traction power supply system and a power flow control method thereof, and relates to the technical field of electrified railway traction power supply. The intelligent three-phase traction power supply system is provided with a power flow regulation and control device and a controller, double-side power supply is carried out on a traction network, and the power flow regulation and control device is controlled to realize self-utilization of power generation power flow according to three-phase bus voltage and three-phase feeder current electric quantity information, so that the power generation power flow returned to a power grid is zero; under the condition that a three-phase power supply structure of a power grid to an electrified railway is not changed, the crossing tide is utilized, the negative influence of the crossing tide on the power grid and a user is eliminated, the advantages of three-phase power supply are brought into full play, and regenerative braking energy can be directly supplied to a traction substation power distribution system.

    本发明提供了一种智能三相牵引供电系统及其潮流控制方法,涉及电气化铁路牵引供电技术领域。智能三相牵引供电系统设置潮流调控装置和控制器,向牵引网实施双边供电,根据三相母线电压和三相馈线电流电量信息,控制潮流调控装置实现发电潮流自我利用,使返回电网的发电潮流为0;本发明在不改变电网对电气化铁路三相供电结构情况下,使穿越潮流得到利用,消除穿越潮流对电网和用户的负面影响,使三相供电的优点得到充分发挥,并有利于再生制动能量直接向牵引变电所配电系统供电。
