Abstract

A method for operating a wind power plant which is provided with a device for regulating the speed of a rotor of the wind power plant. The method includes the steps of: determining the critical frequency of the respective turbine and/or turbine components, determining the speed range of the rotor in which the entire turbine and/or individual turbine components are excited in the vicinity of their critical frequencies and operation of the wind turbine plant only below and above the critical range; the latter being traversed rapidly.
