Non-Stationary Stabilized Fast Transversal RLS Filter for Online Power System Modal Estimation
IEEE Transactions on Power Systems（2019）
摘要
Online monitoring of inter-area oscillations is a vital need for secure operation of large-scale power systems. This paper aims at online estimation of inter-area modes by a novel stabilized fast transversal recursive least squares (SFTRLS) filter running on ambient power system data received from phasor measurement units. The SFTRLS filter is a fast finite-impulse response adaptive filter that is...
