摘　　要：针对风能波动性和间歇性问题,提出了新型机械耦合式压缩空气储能风电系统.建立了风电系统膨胀助力模式混杂动态模型.提出了涡旋机柔性切入、切入后动态协调以及膨胀助力优化控制等三级膨胀助力控制策略,采用输入输出反馈线性化以及前馈控制等方法完成控制器设计.基于1,kW风电系统试验平台验证了控制策略的有效性,提高了模式切换过渡过程和风能捕获的动态速度,有效降低了压缩气体的消耗,涡旋机全效率提升至46.7%.In view of the intermittence and fluctuation of the wind energy, a novel mechanical coupling wind genera- tion system with compressed air energy storage （CAES）was proposed to stabilize the wind fluctuation. Then, the hybrid dynamic model was constructed to describe the expansion assistance mode. The three-level control strategy was proposed with the scroll cutting-in, dynamic coordination and expansion assistance mode optimized control, and then controllers were designed by the input-output feedback linearization and the feed-forward control. Based on the 1 kW wind generator system experiment platform, control strategy has been validated with the lower compressed air consumption, the faster mode switch, maximum wind energy capture, and the scroll whole efficiency reaches 46.7%.
