Locating the source of forced oscillations using PMU measurements and system model information

Abstract

Forced oscillations (FO) in power system are frequently an indication of the ill-operating behavior of different equipment in the system, such as an excitation system, turbine governor, control valve, etc. Corrective actions can be taken only after identifying the source of the disturbance causing these oscillations. In this paper, a novel method is proposed for locating the source of forced oscillations using PMU measurements and system model information. Simulation results obtained by implementing the proposed method on the minniWECC model validate the effectiveness of the proposed method.
