Abstract

A method for operating a wind energy plant in which the ambient air around the generator and the temperature of the generator itself are determined using temperature sensors (22,24). The temperature difference is determined and if necessary the generator is heated so that its temperature is equal to or greater than the surrounding air temperature. An independent claim is made for an operating method in which the humidity precipitation is measured on the generator or other electrically sensitive plant components and the generator heated if the humidity precipitation lies above a pre- determined level.

Description

technical field

[0001] The invention relates to a method of controlling a wind power installation and, in particular, to a wind power installation for carrying out the method. Background technique

[0002] Wind energy installations have long been known and have recently been increasingly used as environmentally friendly energy generators.

[0003] Wind energy installations are logically exposed to the influence of the weather. A problem which has a great impact on wind energy installations is moisture, and wind energy installations with electrical systems must be protected to a greater extent against moisture.

[0004] However, such devices cannot be hermetically closed to reliably prevent the ingress of moisture, so moisture must be kept away from certain parts of the device by additional encapsulating means such as housings. However, such an encapsulation is not feasible, especially in the region of wind energy plant pods with relatively large metallic masses such as gen...
