摘要
串联混合有源电力滤波器是为解决供电质量问题而设计的一种有源滤波器,谐波检测的方法对于有源滤波器技术的研究尤为重要。根据通用瞬时功率理论,针对传统的检测方法在三相电压不对称或畸变情形下的不足,提出一种基于同步参考坐标法的谐波电流检测方法,并将该方法成功地应用于三相电压不对称及畸变的串联混合有源电力滤波器补偿电路中。使用PSIM搭建谐波检测电路以及串联混合有源电力滤波器电路,进行了仿真。理论分析和仿真结果均表明,这种谐波电流检测方法的有效性。
The main goal of the hybrid series active power filter is to solve the problem of power supply. The approach of harmonic detection has an important role in the research of APF. Because of the shortcomings of the traditional detection methods in symmetrical 3 - phase circuits or distortion circuits, this paper presents an approach of harmonic current detection based on Synchronous Reference Frame and uses it successfully on the symmetrical 3 - phase and distortion circuits. The harmonic detection current and a hybrid series active power filter current are designed, and the simulation has been done by the PSIM software. The theoretical analysis and simulation results demonstrate that the proposed method of harmonic detection is valid.
