A data driven approach using local measurements to locate turbine governors causing forced oscillations

Résumé

Submission information: this work has been submitted to the IEEE for possible publication. Copyright may be transferred without notice, after which this version may no longer be accessible. Abstract: This paper presents a method to localize the source of forced oscillations due to power plant turbines and turbine governors based on model validation and system identification techniques. The method identifies the closed loop dynamics of power plants described by the swing equation. When forced oscillations are detected, they are located by finding the transfer functions that describe the behavior of the corresponding plants worse. The method presented in this paper locates the source of forced oscillations based only on local measurements at each plant. This may represent an inherent advantage since it may reduce the need of data measurement and communication. The performance is demonstrated by a n with an hardware-in-theloop approach using a real time simulator and real phasor measurement units. Sensitivities of the method is analysed using a simulation tool.
