摘要
在分析混合型有源电力滤波器(HAPF)工作原理的基础上,对其两种控制策略下谐波和谐振抑制特性进行了分析和对比,提出了同时检测电源谐波电流和电源谐波电压来控制HAPF输出电流的新型控制策略,应用劳斯判据对其稳定性进行了详细分析,分析结果表明系统变得稳定,谐波补偿效果变得理想。仿真及实验结果验证了本文所述控制策略在谐波控制及系统稳定的有效性和可靠性。
Based on the analysis of hybrid active power filters（HAPF） for basic working principle,the analysis and comparison of the two types control strategies for its harmonic and resonant suppression characteristics is given.A new control strategy is proposed with detection of supply harmonic current and supply harmonic voltage to control the output of HAPF.A detailed analysis for its stability is given in Routh.The results show that the system becomes more stable,and the effect of harmonic compensation has become more ideal.Simulation and experimental results verify the validity and reliability of the control strategy described.
