CFD-based analysis of pumped storage power plants implementing hydraulic short circuit operations
Elena Vagnoni, Alessandro Morabito
Hydraulic short circuit (HSC), corresponding to the simultaneous operation of the pumps and turbines, enhances the power flexibility of a pumped storage power plant (PSPP). However, comprehensive analyses are imperative to guarantee a secure and reliable o ...
Elsevier Sci Ltd2024CFD simulations of hydraulic short-circuits in junctions, application to the Grand’Maison power plant
In the framework of the XFLEX HYDRO H2020 European Project, the pumped-storage power plant of Grand'Maison (France), owned by Electricité De France, focuses on the implementation of the hydraulic short-circuit (HSC) operating mode. This mode increases the ...
2022CFD simulations of a Y-junction for the implementation of hydraulic short-circuit operating mode
François Avellan, Cécile Münch-Alligné, Daniel Biner
In the framework of the XFLEX HYDRO H2020 European Project, one of the demonstrators focuses on the implementation of the hydraulic short-circuit on the pump storage power plant of Grand-Maison owned by Electricite De France (EDF). The Grand-Maison power p ...
IOP PUBLISHING LTD2021A scalable, line-independent control design algorithm for voltage and frequency stabilization in AC islanded microgrids
Giancarlo Ferrari Trecate, Michele Tucci
We propose a decentralized control synthesis procedure for stabilizing voltage and frequency in AC Islanded microGrids (ImGs) composed of Distributed Generation Units (DGUs) and loads interconnected through power lines. The presented approach enables Plug- ...
PERGAMON-ELSEVIER SCIENCE LTD2020Predicting the dynamic behavior of Francis turbine generating units
To reduce CO2 emissions and tackle global warming, an increasing amount of electrical power consumed around the world must be obtained from renewable sources. Among these sources, hydropower has not only the advantage of leaving a very small carbon footpri ...
EPFL2019Procedure for predicting part load resonance in Francis turbine hydropower units based on swirl number and local cavitation coefficient similitude
François Avellan, Christophe Nicolet, Arthur Tristan Favrel, Christian Landry, Sébastien Alligné, Loïc Andolfatto
Francis turbines operating at part load conditions develop a cavitation precessing vortex known as a vortex rope in the draft tube cone below the runner outlet. At part load conditions, this vortex precession acts as an excitation source inducing pressure ...
ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD2019Reduced scale model testing for prediction of eigenfrequencies and hydro-acoustic resonances in hydropower plants operating in off-design conditions
François Avellan, Christophe Nicolet, Arthur Tristan Favrel, Christian Landry, Sébastien Alligné, Joao Gomes Pereira Junior
The massive penetration of the electrical network by renewable energy sources, such as wind and solar, pushes the operators to extend hydropower plant units operating range to meet the transmission system operator requirements. However, in off-design opera ...
2019Measurements of Cavitation Compliance in the Draft Tube Cone of a Reduced Scale Francis Turbine Operating at Part Load
François Avellan, Christophe Nicolet, Arthur Tristan Favrel, Christian Landry, Joao Gomes Pereira Junior
Francis turbines operating at part load conditions typically experience a cavitation vortex rope immediately at the runner outlet. As the compliance of this cavitation flow is much higher than the one in cavitation-free conditions, a decrease in the value ...
2018Model testing beyond the scope of International Standards: an outlook.
François Avellan, Loïc Andolfatto
The roles of hydropower plants within the energy system has been evolving during the last two decades. The potential to provide ancillary services to the grid is often harnessed, leading to a major change in hydropower plants operations. Ancillary services ...
2018Transposition of Francis turbine cavitation compliance at partial load to different operating conditions
François Avellan, Arthur Tristan Favrel, Christian Landry, Joao Gomes Pereira Junior
Francis turbines operating in part load conditions experience a swirling flow at the runner outlet leading to the development of a precessing cavitation vortex rope in the draft tube. This cavitation vortex rope changes drastically the velocity of pressure ...
