Simulation Research for Suppressing Gyroscopic Effect of Maglev Flywheel Energy Storage System
the maglev flywheel energy storage system is a kind of high efficiency ways for energy storage and conversion. It has many advantages such as zero-millisecond switching time, high efficiency, high energy storage density, low maintenance costs, long life-time, and no pollution. It has been applied widely. Since the flywheel energy storage characteristics, the moment of inertia ratio between pole and equatorial is large, gyroscopic effect in high speed greatly influence the rigid modes frequencies and stability of the flywheel rotor, the traditional decentralized PID control has been unable to meet the requirements. The cross-feedback algorithm is used to suppress the effect of the gyroscopic effect of magnetic levitation system which simulated by MATLAB. From simulation results, the measurement error of rotor speed, the size of attenuation factor and the delay time of control system will influent the suppression effect of gyroscopic effect with the cross feedback control algorithm, the ranges of influence factors is cleared with simulation to ensure the effectiveness of cross-feedback control algorithm, and laid the foundation for further engineering application.
