Abstract

To prevent the off-grid phenomenon of wind turbines caused by voltage sag and realize the low-voltage traverse operation of doubly-fed induction wind turbine (DFIG), the elite strategy ant colony algorithm was used as a parameter optimization mechanism in the active disturbance rejection control (ADRC) system of the doubly-fed induction wind turbine. To make doubly-fed motor active disturbance rejection system have self-learning ability, an ant colony algorithm with distributed search and parallel computing ability is added to make it have automatic parameter optimization ability. After the simulation analysis of common ADRC and ant colony optimization ADRC, it is shown that the ADRC can improve the ability of low voltage crossing of the system, effectively reduce the transient current on the rotor side, and has good dynamic performance and strong robustness.
