description: The subject of the graduate qualification work is Â«Improvement of operational reliability of the derivation channel of the Dzaujikau hydroelectric stationÂ». In this work, design solutions were developed to improve the operational reliability of the derivation channel the repair of concrete structures of the channel was considered. The tasks that were solved during the study: 1. Analysis of the condition of the derivation channel of the Dzaujikau hydroelectric station. 2. Identification of defects in concrete and reinforced concrete structures of the derivation channel and analysis of their causes. 3. Determination of measures to improve the operational reliability of the derivation channel. 4. Development of structural solutions for repair of concrete and reinforced concrete structures of the derivation channel. The work was carried out based on a comprehensive survey of the hydroelectric complex of the Dzaujikau hydroelectric power station, carried out by employees of JSC VNIIG named after B. E. Vedeneev. As a result of the analysis of the survey results, significant damage to the lining plates of the derivation channel of the Dzau hydroelectric power station was revealed, as well as various violations of the rules for operating hydraulic structures. The filtration losses of the derivation channel and its capacity were calculated. Based on the results of the survey and calculations, the condition of the derivation channel was determined (satisfactory), and measures were developed to increase its service life and trouble-free operation.
