A wind power plant connected to an electric grid. A central plant controller is con figured to carry out a method of controlling an electric output of the wind power plant in the event of a transient low- voltage fault of the electric grid. The central plant controller is configured, after a fault stage in response to detection of a low -voltage fault during which the wind turbines ride through the grid fault , to control the wind power plant during a post -fault- support stage to provide only real power , or perform voltage control. The central plant controller is configured to resume control of the wind power plant according to the nominal -grid operation mode , which prevailed before the low -voltage fault, in a nomi-nal- grid operation stage. |
