摘　　要：对基于电压源型换流器(VSC)的新型直流输电系统(HVDC)的控制策略进行了研究。首先分析介绍了VSC-HVDC的基本工作原理;其次基于同步旋转坐标系下系统的动态模型,引入模糊智能控制,采用直接电流控制策略,提出了双闭环模糊自适应控制器结构,以实现系统有功功率和无功功率的独立调节。最后,通过数字仿真验证了所设计的控制器控制性能良好,对各种干扰与故障都具有较快的适应性和较强的鲁棒性。The control strategy of the VSC - HVDC system are studied in the paper. At first, the elementary structure and model of VSC - HVDC are described. Then the fuzzy self-tuning control strategy is proposed, direct current control strategy and dual closed loop structure are designed,based on dq synchronous reference frame. Decoupled control of the active and reactive power is realized. Simulation results show that the designed control system obtains satisfying performance.
