Definitions
- the present invention relates to a wind power plant with a tower and a rotor arranged on the tower with at least one individually adjustable rotor blade, with a device for detecting the wind direction and a device for detecting the azimuth position.
- Such wind turbines generally have an active drive for tracking wind direction. This rotates the nacelle of the wind energy installation in such a way that the rotor blades of the rotor are aligned in the direction of the wind, provided that the installation is designed as a windward runner.
- This drive required for tracking the wind direction is regularly an azimuth drive, which is usually located with the associated azimuth bearings between the top of the tower and the machine house.
- a company wind measuring system provides an average value for the wind direction over a certain period of time, e.g. B. ten seconds. This mean value is always compared with the current azimuth position of the machine house. As soon as a deviation exceeds a certain value, the nacelle is adjusted accordingly, so that the wind direction deviation of the rotor, the yaw angle, is as small as possible to avoid loss of performance. How a wind direction tracking is carried out in known wind turbines is described in "Wind Power Plants", Erich Hau, 2nd edition, 1996, p. 268 ff. And 316 ff.
- azimuth drives which are often designed as electric motors, have to be actuated for each wind direction adjustment.
- the frequent actuation leads to a high load and accordingly to a relatively rapid aging and high wear on these drives.
- the object of the present invention is therefore to develop a wind energy installation of the type mentioned at the outset in such a way that the service life of the azimuth drives is extended and / or the use of smaller and thus more manageable azimuth drives is made possible.
- This object is achieved according to the invention in a wind energy installation of the type mentioned at the outset by controlling the rotor blade adjustment as a function of a deviation between the wind direction and the azimuth position.
- This control according to the invention enables a considerable portion of the wind direction tracking to be carried out without switching on an azimuth drive, since the forces required for the wind direction tracking can be generated by a suitable adjustment of the angle of attack of the rotor blades.
- the invention provides the possibility, in addition to the hitherto customary azimuth adjustment by means of a motor drive together with the motor drive, or alternatively to carry out the azimuth position by controlling the rotor blade adjustment as a function of a deviation between the wind direction and the azimuth position. Under certain circumstances, this is particularly advantageous if only small azimuth changes have to be made. This protects the motor azimuth drive as a whole.
- the motorized azimuth drive consists of two or more asynchronous motors
- these motors can be supplied with the appropriate three-phase current for azimuth adjustment, but the nacelle is braked by means of a direct current supply for the asynchronous motors and the asynchronous motors are also used during standstill DC supplied so that a mechanical brake is not absolutely necessary.
- the adjustment of the nacelle that is to say the azimuth adjustment, is to be carried out by means of the control of the rotor blade adjustment, the motor braking must be released, which preferably occurs because the direct current is extremely low or zero.
- the deviation between the wind direction and the azimuth position in the case of a platform floating on a floating platform or in the water as a carrier of a wind energy installation according to the invention is determined by detecting the deflection of the platform from the horizontal or the deflection of the tower of the wind energy installation from the vertical determined. In this way, an inclination that necessarily results from a difference between the wind direction and the azimuth position can be detected in a simple manner.
- the wind power installation according to the invention has a slide bearing as an azimuth bearing that, on the one hand, prevents the tower head from striking with rapid changes in the wind direction due to predetermined sliding properties, but on the other hand permits wind direction tracking without sufficient motor force if the forces are sufficiently large.
- a deflection of the tower from the vertical a change in wind direction and the amount of the change in wind direction and its duration are compared with predefinable threshold values. In this way it can be recognized whether it is necessary to start the wind direction tracking.
- Figure 1 is a plan view of a nacelle of a wind turbine.
- FIG. 3 shows a simplified illustration of a control according to the invention
- Figure 4 is a plan view of an azimuth bearing with four drives.
- Fig. 5 is a circuit diagram for an azimuth motor.
- Figure 1 is a plan view of a wind turbine with the machine house 10 and rotor blades 11, 12.
- the fulcrum of the machine house 10 is by a Marked point 20, the main axis of the horizontal axis rotor is identified by a center line 14.
- an existing azimuth drive can be switched on to support the rotation and to reduce the asymmetrical load. This azimuth drive is also required when the wind has completely abated and blows after a still phase from another direction, which prevents the rotor from being adjusted by adjusting the angle of attack in the manner described above.
- Figure 2 shows a wind turbine on a floating platform 30 which z. B. is held by at least two anchor chains 32 in their predetermined position.
- the platform 30 is located below the water surface 2, while the tower 8 of the wind power plant protrudes from the water and supports the nacelle 10 with the rotor blades 12.
- the deflection from the vertical at the top of the tower 8 can already have a clearly detectable amount, so that a detection at the top of the tower 8 is a very sensitive device for detecting a Wind direction change and a resulting deflection can be realized.
- FIG. 3 shows an embodiment for the control of the wind turbine according to the invention.
- a device 40 determines the wind direction.
- This device 40 can e.g. B. a simple wind vane, e.g. B. with an incremental encoder, as is already available on any wind turbine.
- Another device 42 determines the azimuth position.
- These two devices 40, 42 transmit their measurement results or data to a controller 44 which, on the one hand, evaluates and compares the two values from the wind direction detection 40 and the azimuth position detection 42 and, if necessary, makes a suitable adjustment of the angle of attack of the rotor blades using predeterminable parameters via an adjusting device 46.
- B. three threshold values can be predetermined. If the deviation between the two values reaches the first of these threshold values for a certain period of time, the angle of attack of a rotor blade 12 is determined by an adjusting device 46 via a control line 48, e.g. B. to a (not shown) pitch motor, adjusted in a certain segment of the rotor circle in such a way that its air resistance is reduced, so that the nacelle 10 tracks the wind with the rotor until the wind direction and azimuth position again match within predefined tolerance limits , The controller 44 then produces the setting of the rotor blades 11, 12 that is suitable for an optimal energy yield.
- a control line 48 e.g. B. to a (not shown) pitch motor
- the controller 44 e.g. B. on a separate control line 49, turn on the azimuth drive 22 and thus support the wind direction tracking.
- the third threshold value can be determined such that it is then no longer possible to track the wind direction by changing the angle of attack of a rotor blade, so that the azimuth drive 22 is imperative here.
- FIG. 4 shows an active wind direction tracking device by means of a motorized azimuth drive.
- This motor drive rotates the machine head of the wind turbine so that the rotor of the wind turbine is optimally oriented in the direction of the wind.
- Such an active drive for tracking the wind direction can be an azimuth drive 51 with an associated azimuth bearing 52 his. This azimuth bearing is located between the tower head and the machine house.
- an azimuth drive is sufficient; larger wind turbines are generally equipped with several azimuth drives, for example four azimuth drives, as shown in FIG. 4.
- the four drives 51 are evenly distributed around the circumference of the tower head (an uneven distribution is also possible).
- the azimuth drives shown are three-phase asynchronous motors which are used as asynchronous drive machines. For adjustment, for active azimuth adjustment, these three-phase asynchronous motors are acted upon with a corresponding three-phase current, in which they generate a corresponding torque. After adjusting the nacelle (after taking the desired azimuth position), the four three-phase asynchronous motors (ASM) are switched off and therefore no longer generate any torque. In order to brake the motors evenly and to maintain a braking torque afterwards, a direct current is applied to the motors as soon as possible after disconnection from the three-phase network. This direct current creates a standing magnetic field in the motors, which are immediately braked. The DC power supply remains as possible during the entire downtime and the amplitude can be regulated.
- the ASM drives are supplied with a regulated direct current by means of a regulating device (see FIG. 5).
- Slow rotary movements of the tower head which are caused by asymmetrical gusts of wind, are only dampened by a small direct current (approx. 10% of the minimum current), but permitted.
- Faster rotating movements are avoided by an adapted higher direct current and thus higher braking torque.
- the direct current is raised to the nominal current of the motor.
- the asynchronous motor generates with the DC magnetization at standstill no torque. But as the speed increases - up to around 6% of the nominal speed - the torque generated increases linearly and symmetrically in both directions of rotation.
- the direct current of the asynchronous azimuth drives is set to zero or made so low that a controlled adjustment of the azimuth can still take place by means of the rotor blade angle adjustment.
