摘要
Abstract
The wide use of nonlinear power electronic equipment brings out serious harmonic pollution in grid. Restricting harmonic pollution becomes an urgent problem to be solved. The key to restrict and compensate harmonic is to detect harmonic accurately and timely. Firstly, the effect of direct component and changed amplitude on harmonic detection using adaptive notch filter is amalyzed, and a modified adaptive notch filter is designed. Then modified adaptive notch filter can accurately extract direct component, fundamental frequency, harmonic instantaneous value and amplitude when grid includes direct component and changes amplitude. The result of Matlab/Simulink simulation shows that the above-mentioned approach is effective.关键词
