Embodiment Construction
[0069] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0070] figure 1It is a structural schematic diagram of the doubly-fed wind turbine connected to the power system. The doubly-fed wind turbine is connected to the large power grid through the point of common coupling (PCC). When the grid is asymmetrically faulty, the doubly-fed wind turbine makes full use of its rotor-side converter and grid-side converter, while ensuring that the electromagnetic torque of the unit and the double-frequency fluctuation of the DC bus voltage are suppressed, it provides the grid with energy that meets the requirements of the grid code. Minimum reactive current to improve fault ride-through capability and grid-connected power quality of doubly-fed wind turbines.
[0071] see figure 2 , the enhanced low-voltage ride-through control method of the doubly-fed wind turbine under the grid asymmetric fault of the prese...
