GORNO-ALTAISK, March 15 (Itar-Tass) — Hydropower Unit 7 of the Sayano-Shushenskaya hydropower station (SSHPS) comes into operation on Thursday, announced the press service of the administration of the Khakass town of Sayanogorsk.
Prior to the start-up, the hydropower unit was connected up to the power network for the conduct of comprehensive start-up tests, which were carried out under the programme approved by the manufacturing factory with a continuous monitoring of electric parameters, temperature and vibration condition of the power unit.
Power Unit 8 equipment assembly operations are currently under way at the SSHPS. The power unit is to be re-energized in June this year. Work is also in progress inside the crater of Hydropower Unit 9 which is to be re-commissioned in December this year according to the SSHPS overhaul time-table.
The SSHPS least-damaged Power Units 6, 5, 4 and 3 were upgraded in 2010 following the hydropower station breakdown. In 2011, the OAO(public joint-stock company) RusHydro launched a second phase of rehabilitation of the SSHPS. During this phase, ten new hydropower units will be installed in the turbine hall. In the process, four power units, which were re-brought into operation in 2010 after restorative repairs, are to be replaced by new ones. The first new hydropower unit was brought into operation in December 2011.
The new equipment is notable for enhanced performance characteristics that are up to all dependability and safety requirements.
