Impulse turbines are widely used in hydropower plants around the world due to their high
efficiency in a larger operating range compared to reaction turbines. State of the art Pelton …

A deep learning-based defect identification scheme for the Pelton wheel has been
developed. Initially, the raw vibration signal is passed through a time-varying filter based …

The Pelton turbine has been widely used to develop high-head water resources with
sediments because of its advantages in life cycle costs. When a flood or monsoon season …

Fluctuations in the head, discharge, and contaminants in the flow can damage parts of the
Pelton wheel. An artificial intelligence technique has been investigated for the automatic …

Background Pelton wheel works on Newton's law which converts the kinetic energy of fluid
into mechanical energy. Bearing, nozzle, servomotor and buckets are the main components …

Because of the addition of stochastic supply to the power grid introduced by new renewable
energies, hydropower is required to respond rapidly to the fluctuation between power …

The ability of hydropower to adapt the electricity generation to the demand is necessary to
integrate wind and solar energy into the electrical grid. Nowadays, hydropower turbines are …

The startup process occurs frequently for pumped storage units. During this process, the
rotating rate that changes rapidly and unsteady flow in runner cause the complex dynamic …

Transient processes that occur in pumped storage power plants can cause high-pressure
conditions, which in turn can result in vibrations in the pump–turbine structure and even …

Nowadays, one of the major mechanical issues of hydraulic turbines and particularly Francis
turbines are the failures produced by fatigue. Due to the massive entrance of new renewable …
