Abstract

Uninterruptible power supply system (200) uses a slip-ring induction machine (10) and a flywheel combination. The UPS system (200) comprises a back-up power source connected in parallel to a primary power source such as utility grid. During normal operation of the UPS system (200), the primary power source (130) supplies power to the load and the UPS compensates for voltage drop. Moreover, the primary power source keeps the slip-ring induction machine and the flywheel in an excited state above normal synchronous speed. When the primary power source fails, the flywheel, which is rotating at super-synchronous speed and storing kinetic energy, drives the rotor of the slip-ring induction machine to generate power. Accordingly, the slip-ring induction machine and flywheel combination provides instantaneous, short term power to the load until the back-up power source has powered up and been brought online.
