Direct connection of permanent magnet synchronous generator to grid
Chrobák, Petr ; Mach, Martin (referee) ; Ondrůšek, Čestmír (advisor)
This thesis deals with possibility of direct grid connection of permanent magnet synchronous generator. Main benefits of PMSG are briefly compared with classical synchronous generators. There are mentioned all synchronization conditions and their modification in the case of directly grid connected PM generators. One part of this thesis is focused on the damper winding and transient currents shapes during transient state. There is also solved the effect of damper winding on currents shapes. To simulate the case of direct PMSG grid connection there is composed alternative mathematical model of PMSG. Final part of thesis is focused on the simulation of PMSG and there is also made the simulation of PMSG direct grid connection.

Permanent magnet synchronous generator with active rectifier
Michaliczek, Jan ; Cipín, Radoslav (referee) ; Vítek, Ondřej (advisor)
The main objective of the master`s thesis was to prove, if permanent magnet synchronous generator made by company JULI Motorenwerk s.r.o. could reach higher maximum active power with active rectifier than with six-pulse bridge rectifier. For this reason a mathematical model was made in Matlab/Simulink. The influence of the rectifiers with various kinds of loading was observed and compared by simulations on output variables, like line-to-line voltage and active power. The simulations were also compared with measurement.

Home micro-wind power plant
Šmol, Vojtěch ; Máca, Josef (referee) ; Vyroubal, Petr (advisor)
The master´s thesis deals with the construction of micro wind power plants in domestic conditions. Firstly, theory about wind is discussed. In next part, the types of wind turbines and their parameters are listed. Furthermore, the design and production of a domestic micro wind turbine, the design of blades, hubs, brakes and speed sensors are addressed. Furthermore, the design and production of a synchronous generator with permanent magnets produced using 3D printing is carried out. Results from generator testing are shown. In the next part of the thesis, the issue of MPPT controllers is solved, the principle of operation, hardware and software and the results of testing are clarified. The last part deals with the testing of wind power plants in simulated conditions and in real operation.
