| 摘 要： | 针对目前不间断电源(UPS)中化学电池的不足,设计并实现了基于飞轮储能技术的新型UPS系统,提出了高速飞轮充、放电方式的控制策略。飞轮储能单元代替传统的化学电池,具有免维护、寿命长、无污染的特点。充电方式下,通过飞轮转动稳定性的分析,进行了充电曲线的优化设计,针对高速、大惯量负载,采用智能复合控制方法,使飞轮转速很好地跟踪设定的优化充电曲线;放电方式下,根据电机升压斩波能量回馈原理,控制直流母线电压恒定,简化了UPS负载逆变器的控制策略。实验结果表明系统具有很好的动态特性,验证了控制策略的正确性和有效性。

| Abstract: | An uninterruptable power source (UPS) was developed using flywheel energy storage. The flywheel energy storage unit, which replaces the conventional chemical battery, is maintenance free, has long life and emits no pollution. Charging and discharging control strategies were presented for the flywheel. The high speed flywheel stability and the charging curve characteristics were studied to develop anintelligent combined control system with optimized flywheel charging. During discharging, the motor energy recovery algorithm keeps the dc voltage stable which simplifies the power system control. Experiment results show that the UPS has better characteristics and dynamic response. |
