The turbine is a rotating machine that takes the potential energy of the fluid flow. Simple turbines have one moving part, "rotor-blade assembly". Fluid moving makes the propeller rotates and generates energy to drive the rotor. (Jawad al-Din and Steam, 1989)
Based on the working principle of the turbine converts the potential energy of water into mechanical energy, water turbines can be divided into two groups: impulse turbines and reaction turbines.
Turbine act as modifiers of water energy (potential energy, pressure and kinetic energy) into kinetic energy in the form of shaft rotation. Turbine shaft rotation is converted by a generator into electrical energy. The turbines are categorized there are several kinds, including; impulse turbines, reaction turbines, crossflow turbines and kaplan turbines and propeller:
Selection of Turbine
Application areas various types of water turbines are relatively specific. In some areas of operation allows use several types of turbines. Selection of types of turbines in areas overlapping operations require more in-depth calculations. Basically the work area turbine operation by Kepler are grouped into: Low head power plant, power plant head Medium, and High head power plant
