In my thesis work, I examined the use of switched reluctance machines at high speed. Briefly reviewed the theories of the flywheel energy storage and pointed out, why is an ideal choice a switched reluctance machine to flywheel energy storage. I examined and collected the converter topologies, those are useable also in high speed. Due to the high speed use sensorless solution to the position detection. I presented several solutions then compared these methods. I presented the current control in the high speed applications, which is called single-pulse control. In this thesis I presented two different methods for the optimal control angles corresponding calculations. For the method of counting the core losses I wrote a principle with equations, which useable by switched reluctance machines.
In MATLAB Simulink, I created the model of switched reluctance machine. The necessary data’s to run the simulation, has produced with the FEMM 4.2, which is a field simulator. To specify the optimal control parameters for the single pulse operation, I created a program with a graphical user interface in MATLAB. I calculated the copper and iron losses, furthermore the performances of the machine in different speeds and control angles.
The described methods, the majority of the solutions may be suitable for industrial applications. The program will be helpful to choose of an optimal control of switched reluctance motor.
