Embodiment Construction

[0015] figure 1 A schematic diagram of a wind energy installation according to one aspect of the invention is shown. Wind energy installation 100 has a tower 102 with a nacelle 104 and an aerodynamic rotor 106 . The aerodynamic rotor 106 has at least one rotor blade 200 , 201 - 203 . The blade angle of the rotor blades 200 , 201 - 203 can be adjusted, for example, by means of a pitch motor, not shown. The rotor 106 may be locked by means of a rotor locking device 300 . Optionally, a rotor brake 400 may be provided, which serves to brake the aerodynamic rotor 106 .

Abstract

Provided is a method for controlling a wind turbine (100) when starting or running up the wind turbine (100) before the wind turbine (100) is connected to an electric supply network or before the wind turbine (100) is re-connected to the electric power supply network. The wind turbine (100) comprises a rotor (106) having a rotor locking means (300), at least one rotor blade (200, 201-203) and at least one blade angle detecting sensor (600) for each rotor blade for detecting the blade angle of the rotor blade (200). The blade angle of the at least one rotor blade (200, 201-203) is detected by means of the blade angle detecting sensor (600). Unlocking of the rotor locking means (300) is blocked until the at least one blade angle detected lies within a predefined angular range. It is therefore possible to ensure that the rotor locking means is released only when the blades are, for example, in the feathered position.

Description

technical field [0001] The invention relates to a method, a mobile control unit and a wind energy installation for controlling a wind energy installation during start-up or operation. Background technique [0002] During normal operation, the wind energy installation is connected to the power grid and supplies electrical energy to the grid. However, if there is no wind, it can happen that the wind energy installation itself draws electrical energy from the supply grid in order to maintain its operation. [0003] Furthermore, wind energy installations are typically not yet connected to the power grid when they are constructed, and therefore cannot extract energy from the grid in order to control the wind energy installations. In order to control the wind energy installation while the wind energy installation is not connected to the grid, so-called construction aids can be provided, for example. The construction aid can have an electrical power supply and a control unit. ...
