gyroscopic effect of flywheel energy storage

Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 13

This change in orientation is resisted by the gyroscopic forces exerted by the flywheel's angular momentum, thus exerting a force against the mechanical bearings. This force increases friction.

飞轮储能具有功率密度大、能量密度大、响应速度快、使用寿命长的优点，拥有物理转动惯量，适用于需要高频次、快速充放电、电网惯量支撑的应用场景。 机械轴承摩擦损耗与风阻损耗大，难以满足飞轮储能对于低损耗的要求。 将飞轮转子置于真空室内，通过磁悬浮轴承将其悬浮于空中，可以大幅降低摩擦损耗与风阻损耗。 相较于永磁、高温超导等被动磁悬浮轴承，电磁悬浮轴承通过控制电磁铁电流大小主动控制支承力大小，可以实现较好的悬浮效果。 本文开展了磁悬浮飞轮储能系统控制研究，研究了基于三相永磁同步电机的磁悬浮飞轮储能系统的充放电控制与并网运行控制策略、飞轮储能5自由度电磁悬浮轴承控制策略两部分内容。
