Prony Identification of Power Quality Transient Disturbance Signal
Min Juan Zhou · Journal of Chongqing Electric Power College · 2008
In view of the transient disturbance signal of power quality,this paper presents an identification method of analytic signal based on the Prony algorithm.The new method can estimate all kinds of components character,including magnitude,frequency and initial phase produced by accurately fitting the finite exponential functions with least-square method.Simulation results verifies the validity of the developed method.
