现代飞轮储能电源综合了先进复合材料转子、磁轴承、高速电机以及功率电子技术而极大地提高了性能,近10年间,现代飞轮储能电源商业化产品推广应用发展迅速。飞轮储能电源系统在储能容量、自放电率降低等方面还有待进一步提高。飞轮储能目前适合于电网调频、小型孤岛电网调峰、电网安全稳定控制、电能质量治理、车辆再生制动及高功率脉冲电源等领域。随着飞轮储能单元并联技术及超导磁悬浮技术的逐渐成熟,其应用领域将逐步扩展到大电网储能领域。飞轮技术产品处于快速扩张时期,我国应当积极从国家层面支持飞轮储能电源技术研究开发,争取早日推出%The performance of the flywheel energy storage were promoted greatly with the application of advanced composites,magnetic bearings,high speed motor and power electronics.The commercialization of modern FES has made great success in recent 10 years.The merits of FES include long life time,high power,high efficiency and green.However,the shortcomings of FES are small scale in energy for single unit and high self-discharging.Therefore,the FES are very suitable for the application of frequency leveling of the grid,capacity leveling of the small grid,the transient stabilizing of the grid,power quality improvement,braking energy regenerating and high pulse power. The FES technology would be used in large grid with the developing of combination technology of FES unit and high temperature super-conductivity bearing.The research on FES should be supported by the government to develop FES industrial products with high technology.
