摘要
The method involves detecting actual value of a variable of a wind power plant. A hold setpoint is preset for the variable during a holding time, where holding reference value corresponds to the actual value of the variable. A maximum permissible setpoint for the variable is determined, where the maximum setpoint is increased when the hold time is elapsed. The plant is controlled with a reference preset that corresponds to a rotational speed. A presetting of the maximum setpoint is ended when rotational speed-dependent setpoint is lower than the maximum setpoint. An independent claim is also included for a wind power plant.
