description: The purpose of this work is to analyze the causes of the accident at the Sayano-Shushenskaya HPP on August 17, 2009. The tasks that were solved in the course of this work: 1. Review and analysis of accidents at hydroelectric power plants in the world and specifically the accident at the Sayano-Shushenskaya HPP on August 17, 2009; 2. Clustering of hypotheses of the causes of the accident at the SSHPP; 3. Analysis of the version about increased wear of studs on the hydroelectric unit No. 2 of the SSHPP; 4. Design of hydroelectric power plants, selection of the structural scheme of the power plant, the circuit of the switchgear, the choice of hydraulic units, transformers, the number of lines and transformers of their own needs; 5. Calculation of short-circuit currents with subsequent selection of switching equipment; 6. Calculation of the reliability of HPP power supply with complete de- energization of sections for their own needs. The result of this work is an analysis of the causes of the accident at the SSHPP, the designed electrical part of the station and the calculation of the reliability of the power supply of the HPP with complete de-energization of the sections of their own needs.
