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.
