Over the last decade, the power quality market has seen the emergence of several new energy storage technologies that address immediate delivery of energy to critical loads following the interruption of utility power. More recently, industry has seen the reintroduction of one of the oldest energy storage technologies – the flywheel. Advances in the high strength lightweight composite materials, high performance non-contact magnetic bearings, and power electronics technology make Flywheel Energy Storage Systems (FEESs) more suitable for many applications instead of traditional chemical batteries. Wit h increasing interest in the future development of the flywheel energy storage systems, the demand for comprehensive systems design and analysis to aid the development process is rising. Based on a compact and efficient t axial-flux partially-self-bearing permanent magnet flywheel energy storage system, this thesis has presented a co-simulation-based design environment capable of modeling and simulating the overall system behavior. The design environment combines MATLAB/SIMULINK, a system level control system design tool and Ansoft’s SIMPLORER, a sophisticated design tool offering electrical, electromechanical, and control simulation capabilities. The co-simulation technique can provide specific algorithms to achieve optimal performance for the analysis of that specific domain.
