The calculation of 110 kV network distance protection relays setings.
Bartoš, Petr ; Vaculík, Petr (referee) ; Toman, Petr (advisor)
This master’s thesis is about setting of distance protections. The first part is focused on a brief analysis of the basic types of failures and distance protections tripping characteristics and their co-operation with automatic re-turn. The most extensive theoretical chapter is devoted to specific influences that negatively affect the proper operation of distance protections. The practical part is about calculation of symmetrical short-circuit and dissymmetrical short-circuit conditions with consideration of fault resistance and the actual calculation settings of distance protections. Calculations of short-circuit conditions and setting of distance protections are made on a specific part of the network of E.ON in area Prostejov, which is supplied from the substation 400/110 kV Otrokovice.
Program for the calculation of short - circuit conditions in a power system
Bucholcer, Oto ; Václavík, Vlastimil (referee) ; Blažek, Vladimír (advisor)
This master's thesis consists of three parts. The theoretical part deals with short-circuit conditions in the electricity supply system and with the method of their calculation. The practical part includes the programming process of a programme; description of programme properties and functionality. The third part contains the verification of an accurate programme calculation of the examples.
