2009 Sayano–Shushenskaya power station accident case study
Sayano-shushenkaya Hydroelectric Power Station Disaster
1.Introduction
1.1.Brief Dam Description
Sayano-Shushenskaya Hydroelectric Power Station was biggest hydroelectric power station ever built in Russia history, and also the sixth biggest in the worth, which is located on the Yenisei River, near Sayanogorsk in Khakassia.[3]The plant operated ten hydro turbines, made total 6,400 MW of output, average annual produced 23.5 TWH,which peaked in 2006 at 26.8TWH. Its arch gravity dam is 246 meters high ,1,066 meters long, and 110 meters of base width. [10]In addition, it was built strong enough to withstand earthquakes of up to 8 on Richter scale.
1.2.Regional Powerhouse Background[3]
RusHydro Public Corp, owner of the dam, is the leading power company in Russia as private sector, although most of its shares owned by Russian government. It was first established in December 2004 and become second-largest hydroelectric power company in the world. The energy generated by SSH was about 25% of RusHydro energy production for Russia and Siberia. On top of that,70% of Rushydro energy contribute to aluminum production of the world through United company Rusal’s aluminum smelters.
1.3.Follow The Timeline[3]
Accident of august 17 wasn’t first big accident at SSH.From 1978 to 1987,all 10 units of turbine were placed into operation in turn. [10]In March 1979,with Unit 1 and Unit 2 already in operation, a large spring flood overfilled the reservoir and rushed over the running generators and transformers. After 4 months damages were recovered and the units were restarted. There were also two more spring flood attacks in 1985 and 1988 respectively.
