Abstract
Previous work, completed by Dr. Luigi Vanfretti, developed a phasor-only state estimator which used correction factors to account for the inherent inaccuracies found in measurements added from the equipment in the field. This proposed phasor state estimator not only estimates the voltage magnitudes and angles, but also variables that account for measurement error such as angle biases and current scaling factors. Dr. Scott Ghiocel then applied this state estimator to a small subset of the Central New York system in order to study the use of the PSE to a larger system. In this thesis we will study the application of the phasor-only state estimator to a wide-scale power system, enumerate the changes required to adapt the phasor-only state estimator to handle a real system and describe the steps taken to advance the phasor-only state estimator to a near real time application.
