当电网不够坚固时，使用非超导磁体的托卡马克装置需要大量的脉冲功率消耗。在这种情况下，这些设备配备了一些能量缓冲器，以避免对电网的影响。在本文中，我们讨论了采用感应电机/发电机的飞轮储能系统。我们利用感应电机/发电机的自激现象来从飞轮上释放能量。此外，在放电阶段，我们采用了一个附加的自励电容连接到感应电机/发电机。实验结果表明，在一台额定功率为55kW的感应电动机/发电机上，获得了117kW的峰值功率和0.25kW的平顶周期S。
Tokamak devices with non-superconducting magnets require a large amount of pulsed power consumption when the power grids are not robust enough. In this case, these devices are equipped with some energy buffers to avoid the influence on the grids. In this paper, we deal with the flywheel energy storage system employing an induction motor/generator. We used self-excitation phenomena of the induction motor/generator to discharge energy from a flywheel. Furthermore, we adopted an additional self-exciting capacitor connected to the induction motor/generator during the discharging phase. As an experimental result, we achieved 117 kW of peak power and 0.25 s of flattop period using a 55-kW rated induction motor/generator.
