Abstract

This paper proposes the application of frequency locked loop (FLL) based on the second order generalized integrator (SOGI) and a Kalman filter (KF) for frequency adaptive instantaneous power quality (PQ) analysis. The FLL tracks the time-varying grid voltage fundamental frequency adaptively. The orthogonal waveforms of fundamental and harmonic components of grid voltage waveform are extracted using the quadrature signal generator (QSG)-SOGI and a linear Kalman filter (LKF), respectively. The fundamental voltage amplitude is obtained from the orthogonal voltage waveforms as provided by the QSG-SOGI and is fed to an extended Kalman filter (EKF) to extract the instantaneous flicker level (IFL). The proposed SOGI-FLL-KF technique provides accurate instantaneous results for PQ analysis based on the measurement of phasor quantities. Synthetically generated grid voltage waveforms are used in MATLAB/Simulink for instantaneous PQ analysis by the proposed SOGI-FLL-KF technique. The simulation results show that the proposed technique can be used as an effective technique for frequency adaptive instantaneous PQ assessment.
