Abstract
This paper presents a new model that enables linear Kalman filtering ( KF) to be applied for the direct estimation of symmetrical components in unbalanced three-phase systems. Computational experiments implement ing KF using both synthetic and actual data sets are reported. It is s hown that Kalman filtering models are well suited for symmetrical comp onent estimation online. The effects of sampling rate, data window siz e and frequency drift on the optimal estimates are also studied.
