Abstract
Thermodynamic method is a practical solution to determine the turbine efficiency of heads in excess of 100m without need for discharge measurement directly. Efficiency measurement is performed on a horizontal Pelton turbine with 650m rated head and two jets by thermodynamic method in this paper. Determination of specific hydraulic energy, specific mechanical energy, discharge and efficiency of Pelton turbine are discussed accordingly. To avoid the uncertain impact from unstable flow and velocity profile at low pressure section, an improved method to determine the turbine discharge is introduced, in which discharge may be worked out without need for flow velocity measurement at low pressure section.
