The system is reliable, offering easy operation and maintenance, high precision and outstanding safety compared with traditional ring gate systems.
Tianjin Alstom Hydro in collaboration with the Alstom research and development center in Grenoble, France, developed the electronic ring gate control system.
Ahai hydro power station is owned by Yunnan Jinsha River Hydropower and the dam is currently under construction.
The Ahai dam comprises 5×400MW Francis hydro turbine generator units, for which the five turbines are being supplied by Alstom under a contract worth CNY885m ($135.04m).
Alstom said that the first unit will be commissioned in 2012.
