摘要
针对一种适用于高压交流系统的混合有源电力滤波器结构,提出了新的复合控制方法,较好地满足了谐波补偿控制系统稳定性和补偿精度的要求。该方法能精确补偿事先指定的若干次负载谐波电流,同时能削弱泄漏到系统中其余次数的谐波电流,并可以阻尼滤波器支路和系统阻抗间可能的谐振。该方法滤波效果好,实现简单,适用于高压交流系统的谐波补偿。仿真和实验结果证明了复合控制方法的有效性。
This paper presents a novel combined control algorithm for the hybrid active power filter (APF) applied to high
voltage grid. The algorithm can meet the requirements of control stability and harmonic compensation effect at the same time.
With the proposed control strategy, the hybrid APF can compensate some appointed load harmonics accurately and compensate
other harmonics partially. It can also damp the possible resonance between the grid impedance and filter. The algorithm is
characterized by well filtering performance and easy implementation, and is suitable for harmonic compensation in high voltage
system. Theoretical analysis is verified by simulation and experiment results.
