摘要：
To connect the photovoltaic (PV) power generation to the traction power supply system for effective utilization and take into account the improvement of the power quality of the traction power supply system and the recycling of the regenerative braking energy of the train, a coordinated control method based on railway power conditioner (RPC) was proposed to connect the PV and battery system to the traction power supply system. Firstly, the PV and battery system based on RPC was connected to the traction power supply topology, and its power quality compensation mechanism was analyzed theoretically. On this basis, a combined coordinated control method for the PV and battery system connected to the traction power supply was proposed by taking full account of the operating conditions of the PV and battery system and the working conditions of traction, braking, no load, or idling. As a result, the coordinated control of PV + battery + load, the dynamic compensation of negative sequence, and the effective suppression of harmonics in the traction power supply system were realized. To verify the validity of the proposed system structure and the coordinated control method, the simulation model of the PV and battery system connected to the traction power supply system based on RPC was established in the RT-Lab real-time simulation system, in combination with the actual illumination and the data of traction conditions. The results show that the proposed system structure and coordinated control method can realize the effective access of the PV and battery system in the traction power supply system. The regenerative braking energy recovery rate is increased to 86.7%, and the power factor is increased by 6.4%. There is a big improvement in the current ratio of harmonics, especially high harmonics. Therefore, the proposed method can meet the demands of efficient PV power dissipation and comprehensive utilization, dynamic and comprehensive compensation of power quality, and regenerative braking energy recovery. © 2024 Science Press.
