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

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.
