ABSTRACT: Faced with Benin’s electricity deficit and dependence, which cause imbalances in its power system, the exploitation of wind energy has become a necessity. The ability of wind turbines to contribute to the stability of transmission networks improves significantly when high-power units are used. However, this capability is complicated by the intermittent and random nature of wind. For optimal operation, a robust wind turbine system must be able to extract maximum power under low wind speeds and limit it under high wind conditions through its control system. The E115/3MW wind turbine generators are multipole ring-type synchronous machines with very high efficiency. Moreover, the trend is moving toward permanent magnet synchronous generators (PMSG), which offer better efficiency but are exposed to the risk of demagnetization. Within the limits of magnetic saturation, our study aims to evaluate the performance of an E115/3 MW wind turbine equipped with a Permanent Magnet Synchronous Generator (PMSG) under the wind conditions of Benin. The torque control strategy without speed feedback used in this study enabled us to extract the maximum power from the wind. The pitch angle control, based on a simple electric actuator, effectively limited the output power to 3 MW, demonstrating the system’s robustness. For wind speeds around 11.5 m/s, the turbine delivered power levels close to 3 MW, proving suitable for the Sèkandji site. Finally, vector control of the stator currents improved the overall performance of the PMSG.
