Pelton turbines are hydraulic prime movers that convert the kinetic energy of water into mechanical energy. This is achieved by using a specialized water guide system to direct a high-speed free jet onto the runner buckets, causing the runner to rotate and perform work. Water from a pressure pipeline is converted into a high-velocity jet through a nozzle, which then strikes the runner tangentially, causing it to rotate. This rotation drives the generator rotor to produce electricity.
Based on the relative position of the working jet to the runner and the number of working jets, Pelton turbines are classified into:
Pelton turbines are particularly suitable for rivers with high head, ranging from 200m to 800m, and relatively low flow rates. In addition, Pelton turbines benefit hydropower plants with their convenient construction, allowing for quick installation, making them a cost-effective and efficient choice for high-head hydropower projects.
The distribution ring pipe first directs the high-head water flow to the nozzle. Under atmospheric pressure, the nozzle converts the water’s potential energy into jet kinetic energy. The resulting jet impacts the turbine runner’s spoon-shaped buckets (also known as impulse blades), causing the runner to rotate and convert the kinetic energy into mechanical energy. Finally, this mechanical energy is converted into electrical energy by the generator.
Pelton turbines are generally suitable for rivers with high head, typically ranging from 200m to 800m, and relatively low flow rates. In addition to their suitability, Pelton turbines offer practical benefits such as convenient construction, requiring less concrete, and allowing for quick installation, making them a cost-effective and efficient choice for high-head hydropower projects.
The efficiency of impulse turbines can reach up to 95%. For micro-hydropower plants, the maximum efficiency of Pelton turbines can reach approximately 90%.
