[0037] Attached below image 3 The specific implementation manner of the present invention will be described in further detail.
[0038] The centralized fault ride-through device for wind farms provided by the invention is suitable for fault ride-through of wind farms composed of constant-speed asynchronous wind turbines. The device can work respectively in the wind farm operation mode and the unit test mode. In the wind farm operation mode, the device will ensure that the wind farms composed of fixed-speed asynchronous wind turbines within the covered area meet the "Q / GDW-2009 Technical Regulations for Connecting Wind Farms to the Grid" and the wind power grid-connected guidelines of European and American countries. The specified low-voltage ride-through capability requirements of wind farms; in the unit test mode, the device can meet the requirements for the detection of equivalent low-voltage ride-through capabilities of a single fixed-speed asynchronous wind turbine.
