Abstract:

Hydropower generation on steep mountainous streams where storage is impractical can usually be made economical if: the flow duration curve shows sufficient energy available in the high flows to merit extending use to the low end of the exceedance curve - 10 percent or less; the powermax slope and static regain concept are utilized to size and position the long conveyance pipeline; multiple turbines are installed in binary sequence to extend flow range over entire flow duration curve to the 10 percent or less exceedance level. Example applications are discussed.
