Transient Analysis of Variable-Pitch Pump Turbines
Journal of Engineering for Power, 1967A method of analyzing the transient behavior of a pump turbine with variable-pitch blades is presented. A series of equations that describe the behavior of the unit during the transient period is found by interpolation of the unit’s characteristic. These equations are combined with the method of characteristic solution to the waterhammer equations to ...

Pump-turbine addition at TVA hiwassee hydro plant
Electrical Engineering, 1956Studies in preparation for the installation of a second unit at Hiwassee Dam showed that the 26-per-cent additional installed cost of a pumpturbine-type unit was justified by economic and operating advantages. Design and operation characteristics of this 80,000-hp unit, as well as the field test to begiven after initial operation, are discussed.
