Validation experiment design of a PMU-based application for detection of sub-synchronous oscillations

Abstract

This paper presents an approach to design laboratory experiments able to test the functional performance of a PMU-based application. The function of this application is to detect sub-synchronous oscillatory dynamics product of wind farm-to-grid interactions.The designed experiments are carried out in operation conditions similar to those that the PMU-based application would experience in field implementations, while the approach adopted for experiment design takes into account technical limitations of laboratory equipment.The experiments are performed in a laboratory which has been equipped with synchrophasor technology for the purposes of this work. Real PMU devices physically connected on a small replica of a three-phase low voltage micro-grid where oscillations can be systematically injected.

A PMU-based fast real-time sub-synchronous oscillation detection application

“…Finally, paper [21] evaluates the impact of a laboratory setup when performing validation experiments on this tool.…”

“…Figure 1 presents a comparison between SCADA and PMU measurements for this phenomenon. The utilization of PMUs enables observability for phenomena occurring at frequencies up to [15][16][17][18][19][20][21][22][23][24][25] Hz across wide geographical regions, opening new wide perspectives for monitoring and control applications based on synchrophasors. These new tools will help in acquiring a better knowledge on the challenges brought by the increase of intermittent energy sources.…”
