An Asymmetrical Connection Balance Transformer-Based Hybrid Railway Power Conditioning System With Cost-Function Optimization

For solving the emerging power quality problems in electrified railway, an asymmetrical connection balance transformer-based hybrid railway power conditioning system with cost-function optimization (ACBT-HRPC) is proposed in this paper. Compared with other balanced traction transformers, the ACBT is characterized with a much higher material utilization, which really matters in practical applications. Besides, the inductively filtered rectifier transformer, with filter-tuned branches used for filtering harmonics and compensating reactive power, is used as a coupling stage of hybrid railway power conditioning system. The mathematical relationship between power factor and design capacity is analyzed, and the cost-function optimization has been proposed to minimize the investment of ACBT-HRPC, which enables a satisfactory compensation performance with relatively attractive costs. Both the simulation and experimental results verify the effectiveness of ACBT-HRPC.
