Bhavsar, ParthPriyank, JoshiManjunath, K.The objective of this work is to study the performance of Phase-Locked Loop (PLL)-based frequency extraction method. Initially, the frequency of an unbalanced voltage signal is estimated using an available Phase-Locked Loop (PLL)-based approach for different study cases. In specific, the extent of magnitude and phase unbalance on the performance of traditional PLL is evaluated. An attempt is made to enhance the performance of the traditional PLL with the incorporation of compensating component. In other words, a compensator is designed to enhance the response associated with conventional topology with the consideration of deviations in voltage magnitude and phase shifts. The results pertaining to traditional and modified PLL topologies are presented to better understand the impact of voltage unbalance on frequency measurement.
