Abstract
This article discusses the use of an external rotor reluctance machine, operating at high speed (up to 50 krpm), in a Kinetic Energy Storage System (flywheel). The outer rotor acts as a flywheel. This device stores kinetic energy during machine operation as a motor, where it is connected to a DC source. If the primary power supply (DC source) fails, it converts the kinetic energy of the flywheel, allowing the normal operation of a load. Reluctance machine rotation and DC link voltage control techniques are investigated and analyzed through real-time hardware- in-the-loop (HIL) simulations using the Typhoon HIL platform. The choice of how to obtain the angular position occurred after evaluating different techniques present in the literature, having converged to the use of optical sensors. The optimization of commutation angles was applied in the control of operations such as motor and generator. For the purpose of analysis and validation, the results of the HIL are presented, and demonstrate the ability to operate as a generator of the machine, the functioning of the developed system and its applicability.
