Flywheels Protect Power Quality

Add flywheel energy storage systems to your list of options for protecting the power-quality requirements of sensitive electronics. Active Power of Austin has developed a new range of packaged solutions that can fit into a variety of strategies. Its CleanSource systems can be used to protect and extend the life of existing batteries; provide a cost-effective, continuous-power solution as a ride-through to an engine-generator set; or serve as a package solution for glitch or voltage sag. In the first instance, it would provide added protection during off-line battery maintenance, the company adds. To simplify the design, the company integrated the motor-generator/flywheel and bearing rotors into a single moving part. The system is designed to be compatible with all three-phase UPS systems.
