Abstract

Phasor estimation is of great importance for many applications in power systems, such as power quality and protection. However, when the power frequency deviation is present, the phasor would undergo a rotation in the complex plane. This phenomenon will introduce difficulty for the interconnection of power grids and distributed generation systems. In this paper, a synchrophasor estimator based on the combination of harmonic components is introduced for the grid synchronization. With the benchmark and compliance tests in IEEE Standard C37.118-2005, the performance of the proposed solution structure is verified.
