摘要
电能质量对于新能源的开发和利用至关重要,而在有源电力滤波器中,谐波的提取是抑制谐波的先决条件。多重二阶广义积分器可以独立提取特定谐波成分,通过利用谐振频率的无限增益特性来生成APF的谐波指令,这种方法具有灵活性和可调性,适用于那些具有有限功率或抑制能力的APF情况。最后利用MATLAN/Simulink建立APF的补偿系统,进行了一系列实验,包括MSOGI的谐波提取对比实验和特定次谐波补偿实验,验证了其谐波提取算法的可行性和卓越性能。
Power quality is very important for the development and utilization of new energy,and in active power filters,harmonic extraction is a prerequisite for suppressing harmonics.Multiple second-order generalized integrators can extract specific harmonic components independently.In this paper,harmonic instructions of APF are generated by using the infinite gain characteristic of resonant frequency.This method is flexible and tunable,suitable for those APF cases with limited power or suppression capability.Finally,MATLAN/Simulink is used to build APF compensation system,and a series of experiments are carried out,including MSOGI harmonic extraction comparison experiment and specific subharmonic compensation experiment,thus verifying the feasibility and excellent performance of the harmonic extraction algorithm.
