A fully modular tool for small-signal stability analysis of hydroelectric systems

Philippe Allenbach, Basile Kawkabani, Sébastien Alligné, Pedro Camilo de Oliveira e Silva

In electrical systems, the small-signal stability analysis method is usually applied to synchronous machines by using the Park representation (d, q-components). This paper presents the generalization of a different approach for this method, based on a, b, ...

Forced response analysis of hydroelectric systems

François Avellan, Christophe Nicolet, Philippe Allenbach, Basile Kawkabani, Sébastien Alligné, Antoine Béguin

At off-design operating points, Francis turbines develop cavitation vortex rope in the draft tube which may interact with the hydraulic system. Risk resonance assessment by means of eigenmodes computation of the system is usually performed. However, the sy ...

HIL Simulation of a Mixed Islanded Power Network with External DSP Regulator

Philippe Allenbach, André Hodder, Sylvain Robert, Basile Kawkabani, György Atilla Bànyai, Nicolas Junod

The present paper deals with the development of a modular, flexible and structured block to block approach for the study of regulators by implementing the different blocks on a DSP (digital signal processor). The proposed low-cost approach has been applied ...
