In order to further improve the doubly-fed wind turbine high voltage ride-through ability, this article is different from the traditional control research only considering the rotor side converter in the power grid failure in stator flux dynamic changes of active and reactive power decoupling, the influence of the coupling current and the additional quantity of the stator flux changes as the feedforward compensation component in the current reference value. On this basis, an improved control strategy is also proposed for the grid-side converter, which takes into account the power imbalance between the two ends of the DC bus and the voltage mutation of the grid. Simulation in power grid voltage surge, coordinated control based on the grid-side converter and rotor-side converter control strategy of doubly-fed wind power generator of high voltage ride-through the active power and reactive power of wind power unit, the rotor over current, DC bus voltage fluctuations, etc all have better inhibition, effectively improve the doubly-fed wind turbine high voltage crossing ability.
