Carbon Fiber Flywheel systems are used to back up Casinos, Hospitals, Data Centers, and Broadcasting Studios, as well as many other types of critical load environments. Carbon fiber is the most advanced material being used in flywheels today. As a result, flywheels can now take advantage of speed to significantly reduce the size and weight of the flywheel and eliminate high-maintenance mechanical bearings, traditionally found in rotary UPS and steel flywheels, thus eliminating maintenance associated to the rotating mass. When compared to batteries, flywheels offer higher reliability, less maintenance, lower life cycle cost, no hazardous materials and a known state of charge. When flywheels are used with batteries, they preserve the battery by providing the energy required for short outages, voltage fluctuations and when exercising generators. This presentation specifically focuses on carbon fiber flywheel technology and how they are used within power quality applications.
