Structure and Control of Flywheel Energy Converter

Abstract

On the basis of the flywheel energy converter’s structure in wind power turbine, we have used permanentmagnet synchronism motor as energy converter and built mathematical model. We have studied and realized control method of wind power turbine’s constant output power. By analyzing the mathematical model, we have concluded that the needed time of stored energy is three times longer than constant torque control time, and the needed motor power is one second of constant torque control. When flywheel starts from zero speed to basic speed (
