A Synchronous Phasor Tracking Algorithm for Power SignalBased on ASTUKF
The characteristics of high noise and strong transients of power signals in remote distribution network in China cause great disturbance to phasor measurement.The article puts forward a kind of based on the adaptive strong tracking unscented Kalman filter (ASTUKF) power signal synchronous phasor tracking algorithm: according to the characteristics of the distribution of the probability of new interest to build a new system state decision variables to determine whether a system mutated and weakening and STUKF algorithm based on the theory of factor adaptive algorithm, used to establish the fundamental phasor state space modeling based on synchronous phasor ASTUKF tracking algorithm.Experimental results show that the proposed ASTUKF algorithm has good mutation detection ability and can track mutations quickly and accurately.
