Flywheel storage power system
In Ontario, Canada, Temporal Power Ltd. has operated a flywheel storage power plant since 2014. It consists of 10 flywheels made of steel. Each flywheel weighs four tons and is 2.5 meters high. The maximum rotational speed is 11,500 rpm. The maximum power is 2 MW. The system is used for frequency regulation.
Flywheel
The following equation shows the energy of a flywheel [1] : Erotation = Iω2 2 E r o t a t i o n = I ω 2 2 where, • Erotation E r o t a t i o n is the energy stored in the rotational momentum ( Joules, J) • I I is the object''s moment of inertia (kilogram * meters 2, kgm 2 ) • ω ω is the rotational speed (radians per second, rad/s) The ...
Flywheel Energy Storage | Electric Vehicles Research
A flywheel is a rotating disk used as a storage device for kinetic energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a piston-based engine, or when the load placed on it is intermittent. Flywheels can be used to produce ...
