Abstract

This paper uses State Estimation (SE) methods to validate transmission line parameters with Phasor Measurement Units (PMUs) at its ends. This exercise was needed prior to the commissioning of a new network voltage control strategy. Equations for the specific Hydro-Quebec´s measurements scheme are developed. Good behaviour of the algorithm is proven with simulations. The method is applied on a real line with real measurements. A bad data measurement is identified and eliminated. The system under study is then declared coherent.
