摘要
Abstract
A strategy considering the flux transient compensation techniques was introdued to improve the DFIG’s low voltage ride through performance during the power grid’s voltage drop. By detecting and controling the transient induction component in the wind turbine rotor current, together with the active and reactive power control, achieved compensation to the the stator magnetic variation caused by the startor voltage drop, and improved the effectiveness of leakage inductance to the transient flux compensation. A control prototype of 1. 5 MW DFIG was built in MATLAB. Its electromagnetic transient process and safeness was simulated and discussed. Simulation results verified the effectiveness on restraining the peak current of stator and rotor and enhancing the DFIG’s LVRT capability.关键词
