摘　　要：为集中治理电气化铁路的负序、无功以及谐波,提出一种基于两相三线变流器的新型高速铁路补偿装置。该装置包括晶闸管控制滤波器、晶闸管控制电抗器以及两相三线变流器。其中,无源装置补偿无功和部分谐波,降低了有源部分的容量,改善了补偿装置的可靠性能。分析了新型系统的工作原理,并在此基础上提出了其协调控制策略。为提高电流跟踪控制的稳态和暂态性能,提出了基于重复控制的三态滞环电流控制方法。最后通过仿真和实验验证了所提出新型系统结构及其控制策略的正确性和优越性。To compensate of negative-sequence current, reactive power and harmonics in electrified railroad in centralized way, a novel compensation device composed of thyristor control filter, thyristor control reactor and two-phase three-wire converter is proposed. In the proposed compensating device the passive device compensates reactive power and part of harmonics, thus the capacity of active device can be decreased and the reliability of compensation device is improved. The working principle of the novel compensation device is analyzed, and on this basis the coordinated control strategy for it is put forward. To improve steady-state and transient performances of current tracking control, a tri-state hysteresis control method based on repetitive control is given. Both correctness and superiority of the proposed system structure and its control strategy are verified by simulation test and experiments.
