Technical parameters and inviting tenders for units of Xiaowan Hydropower Station

The per-set capacity of Xiaowan Hydropower Station was 700 MW. The technical parameters and tenders mode choice for such super-large sets is very important to steady running and economic benefits. The optimum choice of main technical parameters for the sets was made through special scientific research , experiment and technical consultation. The new tender modes that the bidders should get ready the reports of model turbine developing/testing and the model ventilation results of the generators were adopted. The water turbine generating sets with good performances and inexpensive in price are purchased.
