Advanced Model for Multiphase Generators

György Atilla Bànyai

The current development of generators and power electric drives is characterized by increased power electronic integration. This evolution concerns particularly the variable speed power units allowing both a higher performance and substantial savings on co ...

Light scattering by an array of electric and magnetic nanoparticles

Olivier Martin, Benjamin Syriam Garcia

Light scattering by an array of alternating electric and magnetic nanoparticles is analyzed in detailed. Specific geometrical conditions are derived, where such an array behaves like double-negative particles, leading to a suppression of the backscattered ...

Poly-Phased Matrix Converter for large Synchronous Generators - Design of the Voltage Surge Protection

Alfred Rufer, Antoine Béguin

This paper introduces a special mx3 matrix converter connected between the stator of a poly-phased synchronous generator and a power grid. Some commutations of the chosen switching scheme induce voltage surges due to leakage inductances of the generator. T ...

Lightning Electromagnetic Field Coupling to Overhead Lines: Theory, Numerical Simulations and Experimental Validation

Mario Paolone, Farhad Rachidi-Haeri, Marcos Rubinstein

The evaluation of electromagnetic transients in overhead power lines due to nearby lightning return strokes requires accurate models for the calculation of both the incident lightning electromagnetic pulse ( LEMP) and the effects of coupling of this field ...

Thermally Assisted Transition in Thin Film Based FCL: A Way to Speed Up the Normal Transition Across the Wafer

Joseph Duron, Bertrand Dutoit, Bertrand Dutoit

The adjunction of constrictions along the meander of a superconducting Fault Current Limiter (FCL) greatly improves its behavior thanks to a better distribution of the dissipative zones at the occurrence of a short circuit. This design works perfectly for ...

Improved Modeling of Three-Phase Transformer Analysis Based on Magnetic Equivalent Circuit Diagrams And Taking Into Account Nonlinear B-H Curve

Jean-Jacques Simond, Basile Kawkabani

The present paper deals with a new approach for the study of the steady-state and transient behaviour of phase transformers. This approach based on magnetic equivalent circuit diagrams, takes into account the nonlinear B-H curves as well as zero-sequence f ...

Unbalanced DC-link voltage regulation in a back-to-back 3-level PWM converter for a doubly-fed induction motor/generator

Jean-Jacques Simond, André Hodder, Alexander Schwery

An unbalanced DC-link voltage regulation strategy is proposed for a three-level voltage source inverter used in the rotor cascade of a double-fed asynchronous motor-generator. The major problem in determining the presence of the unbalanced component is inv ...
