Flywheel Terminology

Backup Power:  A supplemental power source that provides emergency power to a load when the main source fails.

 

Capturing and Regenerating Energy: The result of a supply of power for alternating currents (AC) during the up cycle and power regeneration on the down cycle.

 

Charging (Motoring): Like a UPS Inverter, the power module converts direct current (DC) from the UPS to three-phase alternating current (AC) that is applied to the stator and spins the flywheel.

 

Discharging (Generating): In this mode, acting like a UPS rectifier, the power module converts the three-phase AC from the flywheel motor generator to a regulated DC.

 

Energy Recycling: Describes the process of taking the energy component of an application that would otherwise be wasted and converting it into usable electricity or thermal energy.

 

Flywheel Energy Storage System- A flywheel energy storage system of "flywheel battery" is a mechanical battery that stores energy in the form of a rotating mass.

 

Kinetic Energy: The energy of motion as quantified by the amount of work an object can do as a result of its motion. Kinetic Energy = ½ (mass)*(velocity) 2   

 

Peak Shaving: The process of reducing the amount of energy a company purchases from the utility provider during peak hours when prices per kilowatt hour are at their highest.

 

Uninterruptible Power System (UPS): A device that that is used to prolong (maintain) power as a result of a power outage.  When connected to a flywheel energy storage solution, such as the VYCON® VDC®, it is called a flywheel-based UPS.
