摘　　要：在高压直流（HVDC）系统直流侧实现性能优良的有源直流滤波器（ADF）抑制谐波的关键问题之一是ADF的控制器设计。但是，对于超长距离架空线路的HVDC系统，ADF的控制器难以按常规方法设计。针对这一问题，提出了ADF的自校正前馈控制算法及其控制策略，该控制策略不仅能克服ADF对象模型的不确定性及气候变化对ADF控制性能的影响，而且能根据HVDC系统不同的运行方式自动调整控制模型及决策器参数。给出了以葛─南（GZB─NQ）HVDC线路为对象的ADF补偿效果仿真研究，证实所提的ADF控制策略是可行的。The controller design for Active DC filter is very essential in order to realize active harmonic compensation on the DC－side of HVDC system. However, the ADF controller design is very difficulty employing conventional technique for overlong distance overhead DC line in HVDC system. For this reason,This paper proposes a self－tuning feedforward control algorithm and adaptive control strategy. The algorithm not only overcomes the effects of ADF control performance form the stochastic of ADF controlled plant, operation modes and clime changing, but enable self－tuning regulating control models and controllaws according to different operation modes in HVDC system.In the paper, the harmonic compensating simulation has been done for GZB－NQ HVDC system. The simulation results verify that the algorithm and adaptive control strategy presented are feasible.
