Flywheels for Use in Uninterruptible Power Supply Systems
This online engineering PDH course describes flywheel technology, its variations, and installation requirements. It addesses the market for flywheels, advice for choosing appropriate applications, and descriptions of the experiences of several users. One application is highlighted as a case study, followed by an illustrative life-cycle cost comparison of batteries and flywheels.
In a flywheel, energy is stored by causing a disk or rotor to spin on its axis. Advances in power electronics, magnetic bearings, and flywheel materials coupled with innovative integration of components have resulted in direct-current flywheel energy-storage systems that can be used as a substitute or supplement to batteries in uninterruptible power supply (UPS) systems. Although generally more expensive than batteries in terms of first cost, the longer life, simpler maintenance, and smaller footprint of the flywheel systems makes them attractive battery alternatives.
This 1 PDH online course is intended for mechanical and electrical engineers concerned with the design and maintenance of uninterruptible power supply (UPS) systems.
This PE continuing education course is intended to provide you with the following specific knowledge and skills:
- Understanding the flywheel potential alternative use in UPS systems
- Understanding its advantages compared to batteries
- Differentiating between low speed versus high speed flywheels
- Learning about Improved UPS system reliability and reduced life-cycle costs
- Familiarizing with examples of current successful flywheel use
Once you complete your course review, you need to take a multiple-choice quiz consisting of ten (10) questions to earn 1 PDH credit. The quiz will be based on this DOE publication.
