| Abstract: | The instantaneous reactive power method has been introduced briefly in the thesis.After analysing the pq detect algorithm and ip iq algorithm,a novel method for detecting harmonics was proposed,which is able to detect current harmonic and voltage harmonic.In additional,this method can improve the detect accuracy,and also reduce the hardware circuits efficiently in the implemention.Finally,the detailed simulation and experimental results verified the validity of this method. |
