Influence of Wind Farms on Electrical Energy Quality
Bartko, Jan ; Krátký,, Milan (referee) ; Malý, Jiří (advisor)
This thesis is occupied by influences of wind farms on electrical energy quality. Object of thesis was analyse influence of these power plants in a large of number. The first part was attended to presentation of wind turbines producers and their agency on worldwide and European market. At the same time were introduced new technologies of wind power generate. The second part is occupied by influence of wind farms on electrical energy quality. In this part was created model of feed system by GLF software and wind farms were connected into it. By the help of this model was run analyze of local influences of wind power plants on electrical energy quality. In last part was assessed influence of wind power plants feed system integration on electrical energy price, build and operating costs, including the prognosis to the future.

Project of Communication for Distance Protections 7SA 610 Protecting a Transmission Line
Bartko, Jan ; Topolánek, David (referee) ; Orságová, Jaroslava (advisor)
This work describes the structure and function of the distance protection relay Siemens 7SA610 SIPROTEC and presents the basic theoretical knowledge of the communication standard IEC 61850 at the beginning. It focuses on the configuration of the topology of two 7SA610 distance protection relays, PC and secondary relay test set Omicron CMC256 +. These two distance protection relays were programmed by using software implement DIGSI to transmit and receive GOOSE messages. It served to testing this created network by simple function. Computer and tester simulated the control system and commanded auto-reclosure to the first distance protection. Instruction was processed and also sended to the second distance protection. The final objective was to measure the tranfer time of GOOSE message between two distance protection relays. There was used a secondary tester. This measurement was implemented the tester Omicron CMC 256 +, which involves extending the NET-1 and so is compatible with the standard IEC 61850. The results and further actions are summarized in conclusion.
