Estimation of Voltage Symmetrical Components and Current Harmonics Using Multi-Output Kalman Filter

Classification of power quality disturbances based on KF‐ML‐aided S‐transform and multilayers feedforward neural networks

“…The Kalman filter is an estimator which filters out system parameters of an amount of measurement data by minimising the estimated error covariance [19, 20]. To estimate the pure disturbance signals, the state‐space representation to model system should be built for the observed disturbance signal.…”
