Description
Summary:This paper analyzes the electromechanical inter-action in a flywheel system with a doubly fed induction machine, used for wind farm power smoothing or grid frequency response control. The grid-connected electrical machine is subject to power control and this can cause it to produce negative damping to the shaft torsional vibration. Resonance must be prevented and the study proposes a solution by coordinating the design of the electrical controller and mechanical shaft. Computer simulations are used to demonstrate the problem and the proposed solution
