International Journal of Energy ResearchThis paper proposes innovative control schemes for Pelton turbines to improve frequency regulation in isolated power systems with high penetration of variable renewable energy sources (vRESs). Traditionally, Pelton turbine deflectors are used as safety mechanisms; however, this study explores their potential for continuous frequency regulation ...

Hydraulic Design of Pelton Turbines
2016For the hydraulic design of a Pelton turbine, the net head on the pressure side and the desired flow rate are two fundamental parameters. They determine the available hydraulic power supply and therefore the size of the turbine. The design of a Pelton turbine starts with the dimensioning of the Pelton wheel, the choice of the rotational speed, and the ...

Performance measurements on a Pelton turbine model
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2011Pelton hydraulic turbines are impulse-type turbomachines commonly used in hydroelectric plants with medium-to-high water head and in various energy recovery applications. The aim of the present work is to provide detailed performance measurements on a Pelton turbine model, along with the design and geometrical dimensions of its runner/buckets and ...

In mountain areas where plenty of water is available, Pelton turbines are often designed with two to maximum six injectors (Fig. 19.1). Of concern in the design is the minimum displacement, i.e., the offset angle between two adjacent injectors. The jet is allowed to enter the bucket only when the bucket is relieved from the loading by the upstream jet.

Experimental studies of the jet of a Pelton turbine
Proceedings of the Institution of Mechanical Engineers, Part A: Journal of Power and Energy, 2007The jet discharged from the nozzle of a Pelton turbine is a key item of such hydropower systems and its precise shape and position are highly relevant to the optimum design of the turbine buckets to match the incoming flow. Experimental investigations, primarily with laser Doppler anemometry, have been used to identify the important fluid dynamic ...

Numerical analyses of a cavitating pelton turbine
2013Erosive wear of hydro turbine runners is a complex phenomenon, which depends upon many parameters and which leads to a decrease of the performance in time and/or in extreme cases to the rotor mechanical failure. Consistently, the study of this wearing process is an important step to improve the impeller design, to avoid or minimize the rise of ...
