description: Topic of the final qualification work: " Analysis of the causes of failures of switching equipment in distribution devices up to 330 kV". This work is devoted to the development of the electrical part of a thermal power plant, in particular, the calculation of the auxiliary needs of a 200 MW unit. The tasks that were solved during the study: 1. Selection of the structural diagram of the station and power equipment. 2. Selection of the main circuit. 3. Calculation of short-circuit currents.4. Selection of switching equipment, current-carrying parts. 5. Analysis of the causes of failures of switching devices in switchgear up to 330 kV. As a result, the electrical part of a thermal power plant with a capacity of 500 MW was calculated. An effective structural scheme of the station was selected, on the basis of which the main scheme and the scheme of own needs were built, the main power equipment was selected. Short-circuit currents were also calculated, switching equipment and current-carrying parts were selected. An analysis of the causes of failures of switching devices in distribution devices up to 330 kV was also carried out. Typical technical reasons for different types of equipment were identified. Typical organizational reasons were identified.
