Synchronized Profiles of Power Quality Parameters in Assessment of Disturbances in Power Systems with Distributed Generation

摘要

This paper presents implementation of instantaneous voltage-current trajectory (I, U) and its linearization. The aim of the work is to investigate possibility of using the slope of the linearized trajectories obtained synchronously in few measurement points. Field measurement results are presented using wide-area power quality monitoring system installed in distribution network with small hydro power plants.
