摘要
为提升综合电能质量调节器(unified power quality conditioner,UPQC)在不同工况下串联侧抗扰动性能,提出一种在abc坐标系下基于电压、电流前馈的复合控制,对传统电网电压前馈进行改进并引入负载电流前馈,以进一步提升控制器动、静态性能。首先,根据UPQC拓扑结构建立串联侧单相数学模型以分析扰动对系统影响;其次,依据数学模型提出改进的复合前馈控制策略;最后,通过实物试验,分别从不同工况验证了该控制策略在UPQC系统中的有效性及优越性。
In order to improve the disturbance-resistant performance of the series side of the unified power quality conditioner(UPQC)under different operating conditions,a composite control based on voltage and current feed-forward in the abc coordinate system is proposed,which improves the traditional grid voltage feed-forward and introduces the load current feed-forward,so as to further improve the dynamic and static performance of the controller.Firstly,a single-phase mathematical model of the series side is established based on the UPQC topology to analyze the impact of disturbances on the system.Secondly,an improved composite feedforward control strategy is proposed based on the mathematical model.Finally,the effectiveness and superiority of the control strategy in the UPQC system are verified by physical tests,respectively from different working conditions.
