Turbine Speed Governor Parameters Validation in Islanded Production

François Avellan, Jean-Jacques Simond, Philippe Allenbach, Christophe Nicolet, Basile Kawkabani, Bob Greiveldinger

The transient behavior of hydroelectric power plants is of high interest for ensuring stability of islanded electrical power networks. Therefore, it is suitable to determine and validate the set of parameters of a turbine speed governor using a realistic s ...

Methodology for Risk Assessment of Part Load Resonance in Francis Turbine Power Plant

François Avellan, Jean-Jacques Simond, Philippe Allenbach, Christophe Nicolet, Bob Greiveldinger

At low flow rate operation, Francis turbines feature a cavitating vortex rope in the draft tube resulting from the swirling flow of the runner outlet. The unsteady pressure field related to the precession of the vortex rope induces plane wave propagating i ...

High-Order Modeling of Hydraulic Power Plant in Islanded Power Network

François Avellan, Jean-Jacques Simond, Philippe Allenbach, Christophe Nicolet, Basile Kawkabani, Bob Greiveldinger

Numerical simulations of the transient operation of an islanded power network subject to load rejections are performed. The islanded power network case study consists of a 1-GW hydroelectric power plant featuring four generating units, a long penstock, and ...
