A WIND POWER PLANT WITH IMPROVED RISE TIME

摘要

The present invention relates to a method for controlling a wind power plant connected to an electrical grid, the wind power plant comprising at least one wind turbine generator and a power plant controller, the power plant controller comprising a signal controller for controlling an electrical parameter with a gain (Kgs), the method comprising, measuring at least one electrical parameter in the electrical grid, determining an internal signal value at least partially based on the at least one electrical parameter, comparing the internal signal value with a saturation value, and if the internal signal value exceed the saturation value, increasing the gain (Kgs) of the signal controller to a first gain value, in order to decrease a rise time for a slope for the electrical-parameter in the electrical grid. The invention also relates to a power plant controller arranged to decrease a rise time for a voltage slope for a voltage parameter in the electrical grid.
