Voith Siemens Hydro Shanghai has received a 75 million euro (US$110.1 million) contract to supply generating equipment to the 2,600-MW Dagangshan hydroelectric project on China’s Dadu River.
The Chinese operating unit of German-based Voith Siemens Hydro Power Generation received the contract from Guodian Dadu River Hydro Power Development Co.
The Shanghai-based unit is to supply four Francis turbines of 650 MW each. The first unit is scheduled for commissioning in 2013, with project completion in 2014 in Sichuan Province.
Voith Siemens said the large turbines will be designed with ring gates for shut-off purposes. Located between the wicket gates and the stay vanes of the turbine, ring gates are lowered and raised through a specifically designed electro-hydraulic motor system. They protect the turbine from silt during unit shutdown, improving its erosion resistance, Voith Siemens said.
