This paper presents a method for torsional vibration suppression of the PMSG-based wind turbine using Hoo observer. Due to the wind speed variation, continuous torsional torque fluctuation occurs from the drive shaft of the windmill . Twisting occurs between the wind turbine and generator due to the difference of the inertia of the windmill and the generator. As a result, the shaft may damage due to the metal fatigue of the shaft. Furthermore, measurement of the torsional torque is difficult in the actual machine . Therefore, a method for estimating the torsional torque is required . The proposed method estimates the torsional torque and suppress the torsional torque of the shaft by using the Hoo controller.

“…The proposed control system operates as a decentralized control system since the H 1 controllers are designed at the exciter and governor system individually [10][11][12][13][14]. the exciter system cannot control the electromechanical oscillations in the frequency range of 0.5 to 2 Hz.…”

The output power fluctuation of such renewable energy power plants as a wind-turbine generator and a photovoltaic system results in frequency deviation and terminal voltage fluctuation. Furthermore, these power fluctuations also affect the turbine shafting of diesel generator and gas-turbine generators, which are the main power generation systems in isolated islands. This article presents a control strategy that achieves torsional torque suppression and power system stabilization. Since the measurement of torsional torque is difficult technically, and there is uncertainty in mechanical constants of the shaft torsional system, the torsional torque is estimated by using a linear quadratic regulator observer with a parameter identification system. The simulation results validate the effectiveness of the proposed control system.
