Patent number: 9181925Abstract: The invention concerns a method for the determination of an azimuth angle for servicing purposes (?w) of a wind power plant with a machinery housing that is rotatable on a tower through an azimuth angle (?) and a rotor that is rotatable on a machinery housing through a rotor angle (?) such that a plurality of combinations of rotor angles (?) and azimuth angles (?) is adjusted, that are determined at the rotor subject to the influence of a turbulent wind field, which is effecting torques, for the adjusted combinations of rotor angles (?) and azimuth angles (?) and the associated azimuth angle (?), a torque envelope of the torque-azimuth angle associations is determined, surrounding areas (U(?)) with comparable sector sizes of the azimuth angle (?) are generated and associated magnitude values of the torque envelope are determined, a surrounding area (U(?w)) with magnitude-wise smaller torque envelope values than the neighboring surrounding areas is selected and the azimuth angle for servicing purposes (?w) isType: GrantFiled: March 14, 2011Date of Patent: November 10, 2015Assignee: R E power Systems AGInventors: Martin von Mutius, Dirk Steudel

Patent number: 8335594Abstract: The invention relates to a method of operating a wind farm intended for connection to an electric power network, which wind farm includes at least three wind turbine generator systems. At least one actual value for a wind speed or a parameter associated with wind speed is determined for each wind turbine generator system which are divided at least temporarily into predetermined groups. A first disconnect value is assigned to one group of wind turbine generator systems and a second different disconnect value is assigned to a second group of wind turbine generator systems. Actual values are assigned to disconnect values, and compared thereto. When the actual value exceeds the disconnect value the associated group of wind turbine generator systems is automatically disconnected.Type: GrantFiled: May 7, 2007Date of Patent: December 18, 2012Assignee: REpower Systems AGInventors: Jens Altemark, Martin von Mutius, Dirk Steudel

Patent number: 8143734Abstract: A method for the operation of a wind power plant 10) with a rotor (12), which has at least one angle-adjustable rotor blade (14), wherein the wind power plant (10) is operated in a first operating mode (71) and/or a second operating mode (75). In the first operating mode (71) a braking process of the rotor (12) is initiated when a rotational speed of the rotor (12) is exceeded, which lies above a first rotational speed threshold value. Also, a method for the operation of a wind power plant (10) with a rotor (12), which has at least one angle-adjustable rotor blade (14), wherein an operating parameter is monitored and a braking process of the rotor (12) is initiated when an operating parameter threshold value is reached.Type: GrantFiled: March 5, 2009Date of Patent: March 27, 2012Assignee: Repower Systems AGInventors: Dirk Steudel, Martin Von Mutius

Patent number: 8057158Abstract: The invention relates to a wind turbine and a method for operating the wind turbine planted in the floor of a body of water. The wind turbine includes a support structure and a rotor, which is arranged on the support structure. The rotor has a rotor blade. The wind turbine operates in a trundle mode in order to reduce the oscillations in the support structure created through mechanical impacts on the support structure.Type: GrantFiled: November 16, 2007Date of Patent: November 15, 2011Assignee: Repower Systems AGInventors: Marc Seidel, Martin Von Mutius, Dirk Steudel

Publication number: 20090102195Abstract: The invention relates to a method of operating a wind farm intended for connection to an electric power network, which wind farm includes at least two wind turbine generator systems (WEA1, WEA2, WEA3, WEA4, WEA5). At least one actual value (vt1(WEA1), . . . , vt3(WEA5)) for a wind speed or a parameter associated with wind speed is determined for each of the at least two wind turbine generator systems (WEA1, WEA2, . . . , WEA5), and the at least two wind turbine generator systems (WEA1, WEA2, WEA3, WEA4, WEA5) are divided at least temporarily into at least two predeterminable groups (G1, G2, G3). At least one first disconnect value (At1(G1), At2(G1), At3(G1)) is assigned to each wind turbine generator system of the first group (G1), and at least one second disconnect value (At1(G2), At2(G2), At3(G2)), which is different from the at least one first disconnect value (At1(G1), At2(G1), At3(G1)), is assigned to each wind turbine generator system of the second group (G2). The at least one actual value (vt1(WEA1), .Type: ApplicationFiled: May 7, 2007Publication date: April 23, 2009Inventors: Jens Altemark, Martin von Mutius, Dirk Steudel

Patent number: 7275912Abstract: The invention relates to a management system for the operation of a wind turbine, which regulates the power output of the turbine. The wind turbine includes a rotor with at least one rotor blade that is positioned at an adjustable angle to the rotor. The management system regulates the rotor speed within a predefined wind speed range by varying the rotor blade angle in order to set a nominal output and reduces the output in excess of a defined wind-speed-dependent threshold value. The threshold value is a defined rotor blade limiting angle.Type: GrantFiled: December 20, 2003Date of Patent: October 2, 2007Assignee: Repower Systems AGInventor: Dirk Steudel
