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 ...

Electrical effects in winding of large electrical ac machines application to advanced large size DFIM

Frédéric Michael Maurer

To meet the electrical grid's demand on pump power variation, GE Renewable Energy develops since 10 years variable speed machines (also called Doubly Fed Induction Generators or DFIG). Within turbogenerators, the phenomenon of circulating currents in Roebe ...

Two Full Parameter Identification Methods for Synchronous Machine Applying DC-Decay Tests for a Rotor in Arbitrary Position

Jean-Jacques Simond, Mai Tu Xuan, Frédéric Michael Maurer

The main obstacle to a wide use of dc-Decay tests lies in the necessity to align the rotor with the d- or q-axis, which is very difficult to perform for high-power units. The goal of this paper is to propose and validate standstill dc-Decay measuring metho ...

Two Novel Methods for Parameter Identification of Synchronous Machine Using DC-Decay Test with Rotor in Arbitrary Position

Jean-Jacques Simond, Mai Tu Xuan, Frédéric Michael Maurer

The goal of this paper is to propose and validate standstill DC-Decay measuring methods for a rotor in arbitrary position. The first new method (DC-Decay I) delivers the equivalent circuit with a few measurements. The second new method (DC-Decay III) permi ...
