Operation of offshore wind turbines dependent on the natural frequency of the tower

摘要

Method for operating a wind energy installation which is provided with a device for regulating the rotor speed, with the following steps: DOLLAR A determining the respective critical natural frequencies of the installation and / or parts of the installation, DOLLAR A determining the speed range of the rotor in which excitation of the entire installation and / or individual parts of the plant in the area of their critical natural frequencies, and DOLLAR A operation of the wind energy plant only below and above the critical speed range while quickly passing through the critical speed range.
