simple_explanation
Fuzzy active disturbance rejection control (fuzzy-ADRC) helps manage issues in direct-drive wind turbines that connect to the power grid. It shows that using fuzzy-ADRC can stop sub-synchronous oscillations quickly, in just 0.25 seconds. This is a big improvement over traditional methods like PI control, which don’t work as well. By improving these turbines, we can ensure they work better under different conditions, keeping the power supply stable and reliable. ⚡️

Abstract

For the sub‐synchronous oscillation (SSO) phenomenon that occurs during the grid‐connection process of direct‐drive permanent magnet wind turbine (D‐PMSG), the traditional PI controller is less effective. For this reason, this paper proposes a SSO suppression strategy based on a fuzzy active disturbance rejection control (fuzzy‐ADRC). The strategy replaces the PI controller with ADRC by optimising the control structure of the wind turbine grid‐side converter and combines the fuzzy algorithm to self‐tune the ADRC parameters and dynamically adjust the nonlinear error feedback coefficients to cope with the complexity and uncertainty of the grid‐connected wind power system. The simulation results show that fuzzy‐ADRC can effectively suppress the SSO within 0.25 s, which is significantly better than the traditional PI controller (unable to suppress) and SSDC (suppression time of 0.3 s), and the suppression time is shortened by 0.75 s compared with the sliding mode control (suppression time of 1 s). In addition, it can maintain system stability under different string complement levels and different wind speeds as well as under system faults and grid disturbances.
