Rapid 3-D Magnetic Integral Field Computation of Current-Carrying Finite Arc Segments With Rectangular Cross Section

Basile Kawkabani, Frédéric Michael Maurer

The computation of 3-D magnetic fields is a demanding task in the analysis of electrical machines and other electromagnetic devices. In this context, integral field calculation provides a smooth solution, high precision and resolution, "on-demand"-calculat ...

Assessment of Power Swings in Hydropower Plants Through High-Order Modeling and Eigenanalysis

Christophe Nicolet, Pedro Camilo de Oliveira e Silva, Basile Kawkabani

POWER plants are subject to introduce disturbances in the power grid, resulting from interactions with the dynamical behavior of the energy source subsystem. In the case of hydropower plants when used to compensate for variations of power generation and co ...

Start-up of a Varspeed Group in Pump Mode, Practical Implementations and Tests

André Hodder, Basile Kawkabani

The present paper addresses the practical implementation in a test bench of different control strategies for the start-up of a varspeed group in pump mode. In varspeed groups using a double-fed induction machine supplied by back to back voltage source inve ...

Estimation of the Armature Leakage Reactance using the Constant Excitation Test

Basile Kawkabani

The adoption of the best available estimate for the stator Leakage reactance is the first step in several equivalent circuit of synchronous machine parameter estimation. However, there is no specific test for its direct measurement. This paper presents a s ...

Forced response analysis of hydroelectric systems

François Avellan, Pedro Camilo de Oliveira e Silva, 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 ...

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

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

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, ...

Increasing Wind Power Penetration in Autonomous Power Systems through No-Flow Operation of Pelton Turbines

Basile Kawkabani, Christophe Nicolet

The integration of wind power in power systems results in a reduction in greenhouse gas emissions. Thus, it has a positive environmental impact. However, the operation of these power systems becomes increasingly complex, owing mainly to random behaviour of ...
