An Effective Method for Detection of Demagnetization Fault in Axial Flux Coreless PMSG With Texture-Based Analysis

نویسندگان

چکیده

Due to its high power densities and compact dimensions, the axial flux coreless permanent magnet synchronous generator (PMSG) is used in a wide range of areas such as wind turbines electric vehicles. It extremely important detect magnetization faults that occur these generators. The occurrence machines with use affects their operation negatively. In this study, an effective method has been proposed demagnetization fault occurring PMSGs. relevant proposes texture analysis-based feature extraction method, which original contrast conventional methods literature. revealed it can be instead time-frequency analysis, frequency spectrum motor current signature analysis (MCSA) methods. Using finite element voltage signals were taken from healthy PMSG 3% 6% fault. Besides, retaken at different speeds loads. After converted into images, using features obtained images LBP, diagnosis processes carried out Knn. was tested both rates under load speed conditions test whether worked properly. success rate observed 97.16% 100%. With detected

Experimental and 3D Finite Element Analysis of a Slotless Air-Cored Axial Flux PMSG for Wind Turbine Application

In this research paper, the performance of an air-cored axial flux permanent magnet synchronous generator is evaluated for low speed, direct drive applications using 3D finite element modeling and experimental tests. The structure of the considered machine consists of double rotor and coreless stator, which results in the absence of core losses, reduction of stator weight and elimination of cog...

Discrete Time Control Method for SVM Direct Active Power and Stator Flux Control of PMSG-Based Wind Turbine

This paper proposes a new method for direct control of active power and stator flux of permanent magnet synchronous generator (PMSG) used in the wind power generation system. Active power and stator flux are controlled by the proposed discrete time algorithm. Despite the commonly used vector control methods, there is no need for inner current control loops. To decrease the errors between refere...
