Technical FAQs 4

What is a flywheel power system?

Flywheel power systems, also known as flywheel energy storage (FES) systems, are power storage devices that store kinetic energy in a rotating flywheel. The flywheel rotors are coupled with an integral motor-generator that is contained in the housing. The motor-generator is used to store and then harness energy from the rotating flywheel.

How does a flywheel energy storage system work?

Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to produce electricity.

What is flywheel energy storage system (fess)?

Flywheel Energy Storage System (FESS) is an electromechanical energy storage system which can exchange electrical power with the electric network. It consists of an electrical machine, back-to-back converter, DC link capacitor and a massive disk.

How are flywheel energy storage systems rated?

Flywheel DC energy storage systems are rated in either kilowatt-hours (kWh) or megawatt-hours (MWh), which equates to the amount of power that is available over a given time frame. Large-scale flywheel energy storage systems are measured in MWh's and use several flywheels that are coupled together.
