| Abstract: | The rapid,accurate and real-time detection of harmonic instantaneous values is the foundation of active power filter operation with high performance.This paper proposes a new real-time detection method for power system harmonics based on algebraic transformation of multi-frequency sine and cosine,and expounds the basic theory of the algebraic transformation and techniques to detect the instantaneous values of the random harmonics and the total harmonic.Simulation results show the validity of the proposed method. |
| Keywords: | harmonics real-time detection algebraic transformation sine cosine |
