“…Reference [3,4] used the ANSYS to create the 2D static finite element model of generator on no-load working situation, and magnetic field distribution and air-gap flux density curves of normal and fault situations were got. Reference [5] established a 2D transient model using the finite element method, and contrasted the derivative of air-gap flux density curves under the normal pole and the faulty pole. Reference [6,7] calculated the unbalanced force of rotor when rotor inter-turn short-circuit fault and rotor eccentricity occurs at the same time.…”

Rotor inter-turn short-circuit is a common fault in generator and it is a research hotspot to identify the fault at its early stage. Considering the disadvantage of circuit analytical method, this paper establishes a 2D transient finite element electromagnetic-circuit coupling model, and calculates the magnetic field at normal and fault situations through the powerful post-processing function of ANSOFT, then magnetic flux density cloud pictures and air-gap magnetic flux density curves of different operating conditions are got. Using MATLAB to analyze and deal with the air-gap flux density cures, we can get the differences of faults in different levels and different positions, which provide a basis for further study of rotor inter-turn short-circuit fault.

International audienceThe goal of this paper is to identify rotor inter-turn short-circuits of an alternator. The detection method is based on the analysis of a flux probe signal located in the air gap of the machine. Previous works have shown that pattern recognition can be applied to detect such a fault by using the experimental data as prototypes. A new method is developed here by considering a learning step based on simulation. Therefore the machine is modeled and validated in that purpose. A feature selection is made by considering feature correlation and disparity. Finally, k nearest neighbors is used to classified experimental test data
