Small Kaplan Versus Tubular and Francis Turbines
Mossefossen Power Plant is situated in the centre of the small town Moss in the southern part of Norway. Water flows from an existing dam through a 9 m**2, 175m long tunnel to the powerhouse...
Design Criteria for Generators in Low-Head Hydro-Power Plants
Principal characteristics and design features of such generators are discussed and options and preferences in their selection mentioned. Effects on inertia constant, efficiency, reactive...
Index Testing?Relative Turbine Performance
The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head...
Interchangeable Runners Can Increase Energy Output
Interchangeable turbine runners can be used to increase energy generation at some hydroelectric power sites. Two different turbine runners can be designed for different design heads or...
Analyses and Field Tests for Hydraulic Transients Sultan Hydroelectric Project
Two in-line Francis units with their long discharge conduit and bypass valves present some unique problems in controlling hydraulic transients in this system. The problems were compounded...
