Single-phase Active Power Filter Based on Space Vector Voltage Control Method

针对单相有源电力滤波器中电流跟踪控制法的不足,提出了一种基于空间矢量电压控制法的新型有源电力滤波器,采用基于鉴相原理的瞬时检测法作为这种有源电力滤波器的谐波电流检测方法.通过理论分析得到了这种有源电力滤波器的谐波电流检测方法和空间矢量电压控制法的方程后,利用MATLAB仿真结果验证了在负载发生变化的情况下,采用这种方案的有源电力滤波器补偿效果良好,而且可以根据需求实现灵活补偿.

According to the lack of current tracking control method for single-phase active power filter, the paper puts forward a new type of active power filter, which is based on space vector voltage control method. The harmonic current detecting method of this kind of active power filter is instantaneous detecting method based on phase distinguishing technology. Through theoretical analysis, it gets the harmonic current detecting method and space vector voltage control method of this kind of active power filter. The MATLAB simulation result shows the good compensation effect of this kind of active power filter in the case of load changes, and it can achieve flexible compensation according to the demand.
