Abstract

A method for operating a wind power plant (WEA) before or during the performance of maintenance work on the wind power plant (WEA). At least one physical condition of the surroundings outside the wind power plant (WEA) induced by wind movement outside the wind power plant (WEA) is detected as an external physical condition. At least one physical condition of a component of the wind power plant (WEA) influenced by wind movement outside the wind power plant (WEA) is detected as an internal physical condition. The at least one external physical condition and/or at least one internal physical condition are evaluated. The at least one external physical condition is compared with a predetermined reference value for the external physical condition. The at least one internal physical condition is compared with a predetermined reference value for the internal physical condition. Depending on the comparison, at least one warning message is generated.
