Power system monitoring using phasor measurements

Abstract

The paper describes investigation of the new opportunities for power system monitoring and control using phasor measurements. Phasor measurements are used for power system model identification in the form of state-space model. Implementing the modal analysis to identified state-space model gives the opportunity to control proximity of the operation point to the feasibility boundary. Also, identified state-space model allows predicting power system transient. All time domain simulations of the research are conducted for two-generator-swing-bus system. Calculations were carried out in Matlab. © 2012, European Association for the Development of Renewable Energy, Environment and Power Quality (EA4EPQ). All rights reserved.
