Abstract :
Harmonic wave is harmful to electric power system and equipment. In this paper a harmonic parameter estimation method based on ESPRIT (Estimating Signal Parameter via Rotational Invariance Techniques; ESPRIT) method is proposed. This method is able to depress noise and has better differentiation capability and estimation precision and stability. Design based on DSP of the harmonic detection test device. Computer simulation results show the effectiveness and superiority of the algorithm.
