Chapter Abstract:
Hydraulic turbines convert the potential energy contained in a head of water to mechanical energy in the rotor of the turbine. The amount of power transferred is proportional to the amount of head across the turbine blades and the flow through the turbine blades. Therefore, in the application of hydraulic turbines, control of the flow of water through the turbine will control the amount of mechanical power developed by the turbine shaft which will, in turn control the amount of electrical power delivered by the hydraulic turbine generator. Fundamentally, flow control is achieved by the use of either wicket gates that control the flow to the turbine blades and/or by the use of variable pitch blades on the turbine rotor. This chapter discusses the three basic types of hydro‐turbine plants: impoundment, diversion, and pumped storage. It also describes the three basic types of hydro‐turbine unit blade designs: reaction, impulse, and kinetic energy units.
