| 摘 要： | 在背靠背三相四象限变流器数学模型的基础上,为两侧VSC分别设计了快速稳定的直流电压和有功功率、无功功率控制器。针对多重化的背靠背四象限变流器,采用了载波移相控制与改进的SPWM调制相结合的方法,减小了电流谐波,提高了功率交换能力。直流融冰装置的柔性高压直流输电（HVDC）试验证明了该控制方法的正确性和有效性。

| Abstract: | Based on the mathematic model of three-phase back-to-back four-quadrant voltage source converter(VSC),DC voltage controller,active power controller and reactive power controller are designed for VSC of two sides.For multiple back-to-back four-quadrant converter,a modified SPWM technique is combined with carrier phase-shifting control,which reduces current harmonic and enhances power exchange ability.Experimental results of flexible HVDC for DC thaw-ice device verify the feasibility and the validity of this ... |
