| 摘 要： | 控制技术是应用变流器在配电网实现电能质量补偿的关键。作者针对三线三电平并联型电能质量调节器提出了在 dq坐标下求取参考电流和应用改进的无差拍控制与校正的电压空间矢量调制相结合跟踪参考电流的控制方法。MATL AB下的仿真结果表明这一控制方法可以使三电平并联型变流器同时完成抑制谐波、补偿无功和不对称的综合功能 ,并且达到良好的动态和静态效果。

| Abstract: | Control technology is needed to improve compensation of power quality with converters. A new method was proposed for the control of three phase tri level voltage source shunt power quality conditioners. The reference current was calculated for the synchronous dq frame and advanced deadbeat control with voltage space vector pulse width modulation was used to trace the reference current. The results of computer simulations with MATLAB show that the proposed scheme can dynamically compensate the harmonics, reactive currents and imbalances. |

| Keywords: | power quality tri level inverter deadbeat control voltage space vector modulation |
