Abstract
The present invention relates a method of controlling a wind power plant connected to an electrical grid, the wind power plant comprises a power plant controller (), a plurality of wind turbine generators () and a STATCOM (), with a STATCOM controller, comprises: controlling the plurality of wind turbine generators in a first control mode, with the power plant controller controlling a reactive power production from each of the plurality of wind turbine generators according to a closed loop control scheme, and controlling in a first control mode with a closed loop control scheme a reactive power production from the STATCOM according to a first setpoint dispatched from the power plant controller, and controlling the reactive power production from the STATCOM in a second control mode from the STATCOM controller according to an electrical measurement in the grid, and controlling the plurality of wind turbine generators in a second control mode, with the power plant controller controlling a reactive power production from the plurality of wind turbine generators, according to a feedforward control or a close loop control, based on a second setpoint from the STATCOM controller, and switching between the first control mode and the second control mode when receiving at least one trigger signal. The invention also relates to a wind power plant according to the method.
