Patent number: 8922040Abstract: A wind energy plant comprising a rotor having blades and a generator driven by said rotor for generating electric energy. The pitch of the blades can be adjusted and a pitch system for adjusting the pitch angle of the blades is provided, which is supplied by a hub power source. An additional electric load is provided on the hub. A pitch power control device is provided which dynamically distributes the power of the hub power source between the pitch system and the additional electric load and further acts on the pitch system such that its power consumption during high-load operation is reduced. Thus, the power consumption of the pitch system during high-load operation can be reduced and additional power provided for operating the additional load. Even large additional loads, such as a blade heater, can be operated in this way, without having to boost the hub power source.Type: GrantFiled: January 21, 2011Date of Patent: December 30, 2014Assignee: Senvion SEInventors: Matthias Peters, Martin von Mutius

Patent number: 8247913Abstract: A method for operating a wind energy installation and a system for implementing the method. An oblique incident flow value, which represents the difference between the wind direction and the direction of a rotor axis of the wind energy installation, and a load value, which represents the load state of the wind energy installation, are determined. A total load value is determined based on the load value and the oblique incident flow value. The rotor rotation speed is reduced when the total load value is above a first limit value. The wind energy installation is shut down when, in addition, a second limit value is exceeded. The method makes it possible to react objectively to oblique incident flows and can reduce a load on a wind energy installation without causing large yield losses.Type: GrantFiled: April 22, 2009Date of Patent: August 21, 2012Assignee: REpower Systems AGInventors: Martin von Mutius, Roland Weitkamp, Jochen Anemueller
