Definitions
- the invention relates to a single-point mooring wind energy plant with two wind energy conversion units each having a rotor, each with a turbine controller assigned to an energy conversion unit, which is set up to control and regulate the respective energy conversion unit independently of the other energy conversion unit according to the operating parameters relating to the respective energy conversion unit.
- Such single-point mooring wind turbines are known, for example, from EIS 2011 140451 A1, EP 1 269 018 A1, DE 10 2013 111 115 B3, EP 3 019 740 B1 and DE 102016 118 079 B3.
- the angle of inclination can be up to 5° or more for large offshore wind turbines, whereby the inclination in turn ensures that the vector of the rotor thrust is no longer in line with the wind direction around the center of rotation of the turbine in the water.
- a torque is generated around the vertical axis of the turbine around the pivot point, so that the entire turbine turns out of the wind direction.
- this object is achieved by the single-point mooring wind energy installation having the features of claim 1, the method according to claim 8, the method according to claim 14 and the method according to claim 15.
- the subclaims each give advantageous configurations of the invention.
- Fig. 1 shows the model calculation of the axial wind speed components over the total area of the two rotors energy conversion units. Three points in time following one another, each 15 seconds apart, are shown. It can be seen that the wind speeds vary greatly in space and time. This leads to considerable alternating loads in the entire structure of the system, with the sum of these loads also leading to a torque around the pivot point.
- a single-point mooring wind turbine 10 which is basically known from WO 2017/206976 A1 and is shown in a perspective view in FIG.
- Point-Mooring-trained anchorage 20 is rotatably set up to rotate out of the wind in the event of uneven wind conditions acting on the rotors, similar to what is already shown for a system with only one rotor in WO 2020/016643 A1.
- the rotor of the wind energy conversion unit 30' on the right as seen in the wind direction rotates clockwise and the rotor of the plant 30 on the left as seen in the wind direction rotates counterclockwise. This leads to better utilization of the guy rope utilization than when the two systems 30, 30' rotate in the opposite direction.
- FIG. 3 shows in a plan view that when there is a higher thrust force of one or the other rotor, indicated by arrows, a rotation, ie a yaw of the single-point mooring wind energy installation 10 around the anchorage 20 counterclockwise ( a) or clockwise (b).
- the invention now consists, according to a particularly preferred exemplary embodiment, in a single-point mooring wind turbine having a plurality of energy conversion units, in which each energy conversion unit has a turbine controller which controls the operating state of each unit in detail and for all monitoring and control processes of the respective energy conversion unit, with a master controller, which is responsible for monitoring and controlling the alignment of the entire single-point mooring wind turbine relative to the wind direction and according to predetermined boundary conditions in the event of deviations in the alignment from the wind direction at least a turbine controller to ensure optimal alignment with the wind direction.
- the master controller takes over the tasks of a controlled start-up and shut-down of both systems.
- the master controller determines the speed (nn, rin), the electrical power (Pu, P 21 ), the wind speed (vn, V2 1 ), the pitch angle (ßn, ß 2i ) and the torque (Mn, M 21 ) of the respective wind energy conversion unit, the setpoint specifications for the speed (ni s , s ) and/or the torque (Mi s , M 2S ) and/or the pitch angle (ßi s , ß 2s ) of the respective energy conversion unit.
- the aim of using a master controller is to minimize misalignment due to wind differences, wind direction changes, possible currents or waves. This can be done by adjusting the torques generated by the energy conversion units, adjusting the pitch angle of the rotor blades and/or adjusting the rotor speed of the rotors. Irrespective of which parameter is used for the control by the master controller, the aim in all cases is the thrust adaptation of the two energy conversion units in order to enable the entire wind turbine to rotate around the vertical axis of the anchor point, i.e. a yaw that achieves an optimal Ensures energy yield through optimal alignment in the direction of the wind.
- the generator torque for that energy conversion unit which is responsible for the higher thrust is briefly reduced and/or the generator torque of the other system is briefly increased.
- the pitch adaptation aims for the same success, in that the rotor blades of the same energy conversion unit are twisted to a smaller angle of attack of the rotor blade profiles compared to the effective direction of flow, in order to reduce the thrust of this energy conversion unit. At the same time or alternatively, the angle of attack of the other system can be increased as far as aerodynamically possible.
- the rotor speed adaptation takes place in combination with the torque adaptation: while the speed of the energy conversion unit generating too much torque is reduced when the thrust is too high, the master controller ensures that the turbine controller concerned reduces the torque when the thrust is too low Speed increase carried out. If the electrical components are designed for this, an energy conversion unit can also be operated briefly with a higher nominal torque and excess power, which increases the energy yield. At the same time, it is conceivable that one energy conversion unit is operated with a higher torque and the second energy conversion unit is operated with a lower torque, so that the overall performance is balanced overall.
- the following parameters can be set for the system control of both systems using the master controller, with the yaw angle deviation as the deviation of the alignment of the rotor axes of the single-point mooring wind turbine compared to the temporal and spatial average wind direction and the yaw controller as the controller software acting on one or both systems in order to achieve optimal alignment is defined: maximum permissible yaw angle error for activation of the yaw control;
- the speed controller changes the thrust on the two turbines by increasing the speed of one turbine or leaving it adjustable and/or reducing it for the other turbine, thus leading to a reduction in thrust.
- the level of the imposed by the speed controller Speed difference as a function of the yaw angle deviation is specified in a value table or defined by a function.
- the controller should be activated when a maximum permissible yaw angle deviation, which can be set as an input parameter, is exceeded. For a clockwise yaw angle deviation seen from above, a maximum difference between the rotor speeds nn - nn of the two turbines with a positive sign is permissible. If the maximum is exceeded, the target value of the rotor speed s of the left-hand turbine seen in the wind direction is reduced to the sum of the current value of the right-hand turbine and the difference in a given table of values.
- a maximum difference between the rotor speeds nn - nn of both turbines is defined with a negative sign.
- a single-point mooring wind energy plant which has at least two wind energy conversion units each having a rotor, a turbine controller assigned to an energy conversion unit and a master controller which acts on the turbine controller and is set up to specify operating parameters which are matched to both energy conversion units. controller owns.
- each turbine controller is basically set up to regulate the respective energy conversion unit independently of the other energy conversion unit according to the operating parameters relating to the respective energy conversion unit.
- the master controller is set up to coordinate the operation of the energy conversion units and, in addition to minimizing the yaw angle deviation, in particular regulates processes such as the controlled starting and the controlled switching off of the single-point mooring wind turbine.
- the energy conversion units are preferably designed to be structurally identical with regard to the rotor diameter, the power and/or the thrust characteristic.
- the turbine controllers and the master controller are not necessarily to be understood as independent physical hardware units. Rather, the named controllers can be functional software units, which can also be included in common PLC hardware (programmable logic controllers). In particular, the turbine controllers and the master controller are software that is processed specifically by a processor.
- the single-point mooring wind turbine also preferably has a device for detecting a yaw angle that deviates from the mean wind direction acting on the single-point mooring wind turbine, the master controller for positioning the single-point mooring wind turbine in a relative to the mean wind direction predetermined yaw angle is established.
- the term “mean wind direction” used in connection with the present invention is the temporally and spatially mean wind direction.
- the mean wind direction and wind speed is determined in particular by means of preferably at least three wind measurement devices, with one wind measurement device preferably being arranged in the area of the energy conversion units and one wind measurement device in the area of the pivot point of the wind turbine.
- a linearly weighted moving mean value is preferably calculated as the yaw angle deviation.
- the linearly weighted moving average is an average value over a defined number of moving measured values, taking into account a weighting factor that depends on the time of the respective measured value within the period of the moving average. For example, with a sliding measurement period of 60 seconds and readings per second that are read in, the current reading is multiplied by the factor A. Each earlier measured value then with a lower factor of e.g. A/60.
- the decrease in the weighting factor is linear here, so that the more up-to-date the measured value is, the more it is included in the moving average. This means that events that happened a long time ago are not taken into account as much.
- the single-point mooring wind turbine has a master controller which, when the single-point mooring wind turbine is aligned at an angle relative to the mean wind direction outside of a predetermined yaw angle range, for positioning the single-point mooring wind turbine within the predetermined yaw angle range is set up.
- the master controller can be set up to effect a yaw angle change that counteracts the amount of the yaw angle change that has occurred when a yaw angle change that occurs within a predetermined time is detected.
- a particularly advantageous embodiment of components that advantageously interact with one another is achieved when the rotors of the single-point mooring wind energy installation are set up to rotate in opposite directions. The advantage of this configuration is that the dynamic loads on the system are largely canceled out due to the opposing torques of the preferably structurally identical energy conversion units and the need for control is very low.
- the invention provides a method for operating a floating single-point mooring wind turbine having at least two energy conversion units, each energy conversion unit having a rotor, with independent regulation of the energy conversion units according to the operating parameters relating to the respective energy conversion unit within one of the Single-point mooring wind turbine acting average wind direction deviating predetermined yaw angle range and on the operating parameters of the one energy conversion unit coordinated control of the other energy conversion unit when aligning the single-point mooring wind turbine at an angle to the mean wind direction outside of the predetermined yaw angle range for repositioning the single -Point mooring wind energy installation within the predetermined yaw angle range or upon detection of a yaw angle occurring within a predetermined time Change to bring about a yaw angle change counteracting the amount of the yaw angle change that has taken place.
- the energy conversion units are controlled in a coordinated manner, provided that the single-point mooring wind energy installation is aligned outside of the predetermined yaw angle range for a predetermined time.
- the predetermined yaw angle range is preferably in the range of at most ⁇ 5°-10° from the temporal and spatial average of the wind direction.
- the repositioning of the single-point mooring wind turbine takes place in particular by changing the torque of at least one of the energy conversion units, changing the pitch angle of at least one of the energy conversion units and/or changing the rotor speed of at least one of the energy conversion units.
- the single-point mooring wind energy installation can also be repositioned by reducing the difference in the rotor speeds of the energy conversion units using a predetermined table showing the dependency of the yaw angle on the difference in the rotor speeds.
- the single-point mooring wind energy installation is preferably switched off, inter alia, when a maximum yaw angle deviating from the mean wind direction is exceeded.
- both systems are switched off simultaneously using the same shutdown procedure.
- a method for starting up a floating single-point mooring wind turbine having at least two energy conversion units, each energy conversion unit having a rotor is proposed, with the steps: after the two systems have been released for operation, depending on the wind conditions, one or the other system start to spin, when a lower threshold speed is reached, this system is accelerated by the pitch control to a predetermined speed limit, where this system speed is kept constant, after the start of the other energy conversion unit, when this predetermined speed limit is reached, the speed of both energy conversion units is reduced to to achieve the speed required for mains operation and the mains coupling of both energy conversion units is carried out simultaneously.
- This refinement enables a controlled start-up without major differences in thrust of the energy conversion units of the single-point mooring wind energy installation, with each turbine controller taking over control of the respective installation independently of the other installation after the start-up.
- a method for shutting down a floating single-point mooring wind turbine having at least two energy conversion units, each energy conversion unit having a rotor, with the steps: shutting down one energy conversion unit according to the switch-off parameters relating to one energy conversion unit, independently of the another energy conversion unit, detecting the switching off of one energy conversion unit, and switching off the other energy conversion unit with switch-off parameters that are identical to the switch-off parameters of the one energy conversion unit.
- a turbine controller has a shutdown procedure for the one associated with the turbine controller Energy conversion unit initiates, whereupon the turbine controller transmits the shutdown parameters to the master controller.
- the master controller instructs the other turbine controller to also switch off the second energy conversion unit with identical switch-off parameters, so that both energy conversion units are switched off essentially simultaneously, taking into account the signal and computing runtimes.
- FIG. 4 shows a schematic view of a particularly preferably designed control system according to the invention, consisting of two turbine controllers and a master controller.
- FIG. 4 shows a schematic view of a particularly preferably designed control system according to the invention for a single-point mooring wind energy plant with two wind energy conversion units each having a rotor, the rotors being set up to rotate in opposite directions.
