Enhancement of high-voltage ride-through of a grid-connected switched reluctance generator (SRG)‎ wind turbine using a dynamic voltage restorer based on fuzzy logic controller

Abstract EN

This paper proposes a Fuzzy Logic Controller (FLC) of Dynamic Voltage Restorer (DVR) to enhance the capability of High voltage Ride-Through (HVRT) for a wind turbine based on a Switched Reluctance Generator (SRG).

Voltage Swell on the grid side may cause the wind turbine to be disconnected from the grid.

Two FLCs are used to regulate the IGBT pulses of the voltage source inverter (VSI) driving DVR by adjusting the D-Q axes voltage signals.

To validate the effectiveness of the DVR based FLC, three test scenarios are investigated includes (balanced swell, unbalanced swell, and total harmonics distortion).

The enhancement of the system performance is achieved through improving the voltage, the current as well as the power waveforms for the wind turbine and fulfill the grid codes without disconnecting the turbine from the grid.

The proposed system is modeled using MATLAB/Simulink.
