The analysis of consequences of possible emergency situations at Zhigulevsk hydroelectric power station

In article the analysis of consequences of emergency situations on Zhigulevsk hydroelectric power station is carried out. The technical characteristics of objects at Zhigulevsk hydroelectric power station is given. Potentially dangerous objects of hydroelectric power station are: overflow dam, roof of the machine hall, hydrounits, main transformers, coppers of oil-pressure units, support and wires of tires systems, intersection seams. Long work (hydrounits finish the second term from norm) in unrecommended zones of loadings is followed by transition hydrodynamic processes, pressure pulsations in a flowing path and the increased vibration of the hydrounit. Even short-term and sign-variable increases - decreases of loadings harmful influence hydrounit support. We made the analysis of operation the hydrounits of hydroelectric power stations of Russia from 1903 to 2014. Together with Rostekhnadzor of of Toglyatti and Syzran actions for decrease in level of vibration of hydrounits on Zhigulevsk hydroelectric power station are developed.
