| Abstract |
This paper deals with the operation of a flywheel energy storage UPS. The UPS has good features such as long life-time, improved efficiency, no environmental problems, reduced size and space, and low maintenance cost compared with the conventional UPS using battery. The operating principle of the UPS is analysed in each mode including voltage compensation as well as uninterruptible power supply. Especially, the tracking characteristic of the disturbed phase of the source voltage after outage is analysed. The usefulness of the system is proved through simulations and experiments. |
