ABSTRACT:
The claimed and disclosed systems and methods are directed to providing measures and possible ways of protecting a wind power installation in a wind park from wind conditions that may potentially cause damage or even result in the failure of at least one of the wind power installations. The wind is monitored in at least one region of the wind park and based on the monitored wind readings; the rotor blades of at least some of the wind power installations may be adjusted to avoid detrimental damage thereto. This protection may be balanced with contemporaneously determining whether other, non-impacted wind installations can be contemporaneously operated at or near their maximum possible energy yield. At least one wind power installation may have a SODAR system mounted thereon to detect the wind in a region of the wind power installation.
