This paper focuses on current harmonics mitigation at the permanent magnet synchronous generator (PMSG) wind turbine system using a variable frequency active power filter (VF-APF) harmonic mitigation technique. Mitigation of current harmonics in the PMSG reduces harmonic losses, thus reducing the heating effect on the PMSG cause by the current harmonic components and extends the lifespan of the PMSG...
The amount of energy obtained from a wind energy conversion system (WECS) depends on the characteristics of the wind regime at the site and the implemented control strategy. In order to determine the gain in energy derived from one control approach as compared against another, models of several autonomous WECS are developed using Matlab Simulink software. These allow easy performance evaluations,...
One of the preferred technologies in variable speed wind turbines (VSWT) is formed by a wind rotor, permanent magnet synchronous generator (PMSG), three-phase bridge rectifier (BR) with a bulky capacitor, and power electronics converter for grid interface. High-intensity, low-frequency harmonic currents flows into the PMSG as electric load has a non-linear characteristic. This paper presents an analysis...
Permanent magnet synchronous generators (PMSG) applied to wind energy conversion system (WECS) using variable speed operation is being used more frequently in wind turbine application. Variable speed systems have several advantages over the traditional method of operating wind turbines, such as the reduction of mechanical stress and an increase in energy capture. To allow the variable speed operation...
Permanent magnet synchronous generator (PMSG) wind energy converters system (WECS) with variable speed operation is being used more frequently in the wind turbine application. Variable speed systems have several advantages over the traditional method of operating wind turbines, such as the reduction of mechanical stress and increase in energy capture. To fully exploit the last mentioned advantage,...
Permanent magnet synchronous generators (PMSG) have been used more frequently as variable speed systems in wind energy conversion systems (WECS). Variable speed systems have several advantages such as yielding maximum power output while developing low amount of mechanical stress compared to constant speed systems. AC-DC converter such as six-pulse rectifier is used to convert variable voltage and...
