Abstract :
A novel discrete wavelet transform (DWT) approach to the computation of synchronized phasors is presented in this paper. Under steady state, the error in the phasor obtained by the proposed algorithm is very small, i.e. 0.001 p.u. in magnitude error and 0.05/spl deg/ in angle error. During transients and considering frequency deviation, the performance of the proposed algorithm is far higher than that in FFT.
