This paper presents a hardware implementation of the participation of a wind turbine to network primary frequency control. The increase of renewable production of electricity requires the participation of these generators to ancillary services. The proposed method, by actions on the pitch angle and the generator torque through fuzzy logic controllers, creates a power reserve. This reserve is regular on a large range of wind speeds and is constituted without any wind speed measurement. Furthermore, the proposed strategy uses this reserve in case of frequency deviation to provide additional active power to stabilise the electrical grid. The implementation of such strategy on a 2.2 kW test bench representing a wind turbine and its generator validates the practical feasibility of the method. Finally, the regularity of the reserve is shown to be weakly dependant on the dynamics of the wind turbine controls.
