【摘要】：有源电力滤波器(APF)是解决由非线性负载造成谐波污染的有效手段之一。基于多同步旋转坐标系的谐波提取策略,兼顾动态和稳态响应,提出一种改进型指定次谐波电流补偿控制策略。该控制策略通过对各次谐波电流进行比例积分(PI)闭环控制,以达到较好的稳态补偿效果;通过无差拍控制解决系统补偿的动态响应问题,实现了指定次谐波电流的补偿,同时保证了系统的动态性能和稳态精度。实验结果验证了所提改进型谐波电流补偿控制策略的有效性。
[Abstract]:APF (active Power filter) is one of the effective methods to solve harmonic pollution caused by nonlinear load. Based on the harmonic extraction strategy of multi-synchronous rotating coordinate system and taking into account the dynamic and steady state response, an improved subharmonic current compensation control strategy is proposed. In order to achieve better steady state compensation effect, this control strategy solves the dynamic response problem of system compensation by means of proportional integral PI closed loop control of each harmonic current, and realizes the compensation of specified harmonic current. At the same time, the dynamic performance and steady-state accuracy of the system are guaranteed. The experimental results verify the effectiveness of the proposed improved harmonic current compensation control strategy.
