Description Générale

The Flywheel Energy Storage Application, "AEL-FES", has been designed by EDIBON for the theoretical and practical training in the field of energy storage systems based on inertial systems such as the flywheel and the elevators with energy regeneration. These systems allow the kinetic or potential energy storage and return it to the grid at a certain moment in the form of electrical energy.

The application "AEL-FES" offers different training levels, providing the user with the essential knowledge and abilities about the fundamental principles of working and operation for the power systems which store energy by means of flywheel.

Basically, the applicaton consists of a big mass flywheel coupled to a squirrel cage induction motor. Initially, the induction motor will be coupled to the electrical grid through a frequency controller which will make the disk speed up progressively. At this stage, the user will be able to carry out measurements of the electrical energy provided to the motor (off-peak hours). Once the motor reaches its nominal speed, the disk can be no longer speeded up and the existing consumption willl be consequence of the system mechanical losses. This is its limit of storaged energy. At the second stage, by means of a regenerative controller, the user will be able to return part of this kinetic energy to the grid (peak-hours). For this purpose, the application includes two network analyzers, one for measuring the energy consumed form the grid and the other one for measuring the energy generated by the electric generator through the previously storaged kinetic energy at the flywheel.
