| description | The invention discloses a low voltage ride through control method for a brushless doubly-fed generator under grid voltage drop, which comprises the following steps: The stator voltage, current and magnetic chain equations for the stator power winding and the stator control winding in the static coordinate system are constructed to analyse and derive the change process of the stator power winding voltage and the response process of the stator power winding magnetic chain during the grid drop, based on the relationship between the voltage equation and the magnetic chain equation, and the stator power winding magnetic chain to express the equivalent voltage equation of the winding. The invention has good dynamic and static performance and robustness. |
