摘要：
Virtual co-phase traction power supply system has important engineering application value because it can eliminate voltage/current shock and locomotive speed loss when it crosses neutral section. Taking the key national project of the 13th Five-Year Plan-Combined Virtual In-phase Flexible Power Supply Equipment to be adopted in the Key Technology Project of High-efficiency Traction Power Supply and Transmission for Rail Transit as research object, the working principle of composite set of devices is analyzed. Based on direct power control theory, a direct power control algorithm for the composite set is proposed. The power control of the composite set can be achieved with this algorithm, and generation of electric arcs is avoided because flexible switching of locomotive power is realized between neutral section and traction power supply ratio. Matlab/Simlink simulation results verify correctness and effectiveness of this control mode. © 2019, Power System Technology Press. All right reserved.
