Analysis of power system transients using wavelets and Prony method

Wind Generator Transients' Computation using Prony Method

“…The right-hand summation in (10) may be recognized as a polynomial defined by (8), evaluated at each of its roots yielding the zero result:…”

“…Transient overvoltages can theoretically reach peak values up to 2.0 pu. High current transients can reach values up to ten times the nominal capacitor current with a duration of several milliseconds [8].…”

Adaptation of SVD and Prony method for precise computation of current components in networks with wind generation

“…The Prony method is a technique for modeling sampled data as a linear combination of exponential functions [8]. Although it is not a spectral estimation technique, the Prony method has a close relationship to the least squares linear prediction algorithms used for AR and ARMA parameter estimation.…”

“…High current transients can reach values up to ten times the nominal capacitor current with a duration of several milliseconds [8].…”

“…Equation (6) can also be written in a practice relevant matrix form 1 0 (8) Generally, the realization of proposed method implies using M-column matrices instead of one column vectors of input signal samples x n .…”
