摘　　要：随着全控型电力电子器件的成本降低和技术不断成熟,电压源换流器技术在直流输电领域得到广泛应用。基于矢量表的直接功率控制由于其结构简单、动态响应快、参数鲁棒性好和无需电流内环整定等优点而得到了国内外学者的广泛关注。研究一种应用于直流输电领域基于直接功率控制的电压源换流器,提出一种有效的控制矢量表,具有很好的稳定性和动态响应。最后以仿真结果验证所提矢量表的有效性。Along with the cost reduction and mature technology of the fully controlled power electronic device, the technology of voltage source converter has been applied in the field of DC power transmission. Direct power control （DPC） is attracting widely attention throughout the world because of its merits of simple structure, quick dynamic response, strong robustness against parameter variations and no need of inner current loop tuning work. The voltage source converter based on the direct power control used in DC power transmission field is analyzed, and an effective vector table is proposed which can achieve a better performance compare to the original vector table. Simulation results validate the effectiveness of the proposed vector table.
