Research paper thumbnail of Modeling and Control of Permanent-Magnet Synchronous Generators Under Open-Switch Converter Faults

IEEE Transactions on Power Electronics, 2019

The proposed converter model is generic for any open-switch fault and independent of the operation mode of the electrical machine. The proposed fault-tolerant current control system gives improved control performance and reduced torque ripple under open-switch faults by modifying the antiwindup strategy, adapting the space-vector modulation scheme, and by injecting additional reference currents. The theoretical derivations of model and control are validated by comparative simulation and measurement results.

Research paper thumbnail of Performance Analysis and Control of 10 KW Permanent Magnet Synchronous Generator Connected to Grid Driven by Wind Turbine Using Autonomous Converters Applying SVPWM Technique

In addition to it SVPWM technique has been applied for 10KW grid connected model. Space vector pulse width modulation has been used for obtaining the output voltage with less distortion. The result so obtained show that there is a degree of freedom of space vector placement in a switching cycle. The fully controlled converter has been used to provide separate control for active and reactive powers. The simulation results in MATLAB SIMULINK 2013a showing the model have good dynamic and static performance. KeywordsDirect drive permanent magnet synchronous generator, space vector pulse width modulation, fully controlled converters.
