Effects of forced oscillations in power system damping estimation
2012 (English)In: 2012 IEEE International Workshop on Applied Measurements for Power Systems, AMPS 2012 Proceedings, IEEE , 2012, 59-64 p.Conference paper (Refereed)
This article analyzes the impact of forced power system oscillations on mode damping estimation. Parametric (Yule-Walker) and non-parametric (Welch) methods for mode estimation are tested in the presence of forced power system oscillations. For mode damping estimation based on non-parametric methods, an application of Half Power Point method is proposed. Performances of the mode estimators are evaluated using both simulated and real synchrophasor data from the Nordic Grid. The presence of forced oscillations poses difficulties to mode damping estimators, these difficulties are identified, illustrated and explained herein.
