Description

A TECHNIQUE FOR SETTING A CONTROLLED COMPONENT OF A WIND TURBINE BASED ON WEATHER PREDICTION

The present invention relates to a technique for configuring a component of a wind turbine, and more particularly to a system and a method for predictably configuring a component of a wind turbine .

Wind energy is emerging as an important source of energy in modern times. Wind turbines are placed in suitable on-shore and off-shore locations to extract optimum uninterrupted power from the wind. However, since wind turbines are placed in open areas, they are subjected to changing weather conditions during their operation. To drive optimum production of power and to keep the wind turbine and its components safe, the wind turbines need continuous monitoring and change in configuration of its components. The change in configuration means setting the component of the wind turbine into a desired state.

For example, if wind speed is very high then the wind turbine blades may get damaged if operated, and thus the rotation of the wind turbine blades is stopped, i.e. the blades are set into a state of stopped. Similarly, when the wind changes direction of flow, then to extract optimum power the nacelle of the wind turbine is moved using the yaw drive to position the blades such that they face the incoming wind with suitable alignment with the direction of the flow of the wind, i.e. the nacelle is set to a state of a desired orientation. Another example may be when the wind speed changes, then to extract optimum power the pitch of the blades are changed such that the blades face the incoming wind at a suitable angle, i.e. the blades are set to a state of a desired orientation. Yet another example may be when temperatures in the surroundings of the wind turbine are too high then the nacelle needs to be cooled to obviate destruction of components in the na- celle by overheating and subsequent fire, i.e. the nacelle chamber is set to a state of cooled.

Thus, the weather conditions in the surroundings of wind tur- bines or wind parks are continuously monitored, and as and when a weather condition changes a report is sent to a central control room which in turn initiates a change in configuration of one or more of the components of the wind turbine as a response to the changed weather condition. Thus, conven- tionally the wind turbines are configured in a reactive manner, i.e. as a reaction to the changed weather condition. However, this is disadvantageous for several reasons. First, when the weather changes to an unfavorable condition, the change in configuration as a response to the changed weather condition means that at least for sometime the wind turbine and its components are subjected to the unfavorable weather conditions i.e. the wind turbine and its components are in a disadvantageous state for the changed weather conditions. Second, when weather changes to a favorable weather conditions, the change in configuration as a response to the changed weather condition means that at least for sometime the wind turbine and its components are not properly utilized to provide optimum output under the favorable weather conditions. According to the present invention, the above mentioned problem may be solved by equipping the wind turbines and/or wind parks with a technology that can change the configuration of the components of the wind turbine before the change in the weather takes place, i.e. the change in configuration of the components of the wind turbine in a predictive manner.

It is therefore an object of the present invention to provide a technique for predictably configuring a component of a wind turbine .

The object is achieved by a wind turbine configuration system according to claim 1 and a method for predictably configuring a component of a wind turbine according to claim 9 of the present technique.

According to a first aspect of the present technique, a wind turbine configuration system for predictably configuring a component of a wind turbine is presented. The component of the wind turbine is predictably configured by setting the component of the wind turbine to a state selected from a set of states. The wind turbine configuration system includes a central repository, an interface, a schedule generator and a schedule implementation module.

The central repository stores a set of states for the component of the wind turbine and a set of weather condition en- tries. Each state corresponds to at least one weather condition entry. The interface is adapted to receive weather forecast data which includes at least one predicted weather condition corresponding to a given time in future and to a geographical location of the wind turbine.

The schedule generator is connected to the central repository and the interface. The schedule generator is adapted to compare the one predicted weather condition from the interface and the set of weather condition entries from the central re- pository, to select the weather condition entry corresponding to the one predicted weather condition, to select the state corresponding to the selected weather condition entry, and to generate a future schedule. The future schedule includes at least one command corresponding to the selected state. The command is adapted to initiate the setting of the component of the wind turbine to the selected state.

The schedule implementation module is connected to the schedule generator. The schedule implementation module is adapted to receive the future schedule so generated by the schedule generator, to communicate the command of the future schedule to the component of the wind turbine, and to set at the given time the component to the selected state. Thus, by utilizing the weather forecast data the component of the wind turbine is predictably configured, i.e. set to a desired or selected or suitable state at a time when the weath- er condition changes and not at a time when the weather condition has already changed.

In an embodiment of the wind turbine configuration system, the weather forecast data includes a plurality of predicted weather conditions corresponding to the given time in future and to different geographical locations. The schedule generator is adapted to select the one predicted weather condition corresponding to the given time in future and to the geographical location of the wind turbine. Thus the system is equipped to work with a weather forecast data of general characteristics that contains information for several geographical locations.

In another embodiment, the wind turbine configuration system further includes a turbine location data module connected to the schedule generator. The turbine location data module stores the geographical location of the wind turbine. The schedule generator is adapted to match the geographical location of the wind turbine with different geographical loca- tions of the plurality of predicted weather conditions to select the one predicted weather condition corresponding to the given time in future and to the geographical location of the wind turbine. Thus, the system is equipped to monitor several wind turbines located at different geographical locations by matching the geographical location of the wind turbine to be configured as stored in the turbine location data module with the weather forecast data to select which predicted weather condition from the forecast data will be applicable to which wind turbine .

In another embodiment of the wind turbine configuration system, a geographical location of the schedule generator and a geographical location of the schedule implementation module are same. Thus the system is a compact system that can be installed in a central control room at the location of a wind park or at a location near the turbine, or at a location remote from the wind turbine.

In another embodiment of the wind turbine configuration system, a geographical location of the schedule generator and a geographical location of the schedule implementation module are different. Thus the schedule implementation module may be positioned at a location near to the wind turbine to be configured and the schedule generator may be installed in a central control room at the location of a wind park or at a location remote from the wind turbine. Moreover, one schedule generator may communicate with a plurality of the schedule implementation module positioned at different geographical locations .

In another embodiment of the wind turbine configuration system, the schedule implementation module is located at a wind park that includes the wind turbine. Thus, the schedule implementation module may easily communicate the command from the future schedules to the component without having to face the challenges of communication over longer distances, and thereby ensuring that a glitch in communication caused by long distance separation between the component and the schedule implementation module is obviated.

In another embodiment of the wind turbine configuration system, the schedule implementation module further includes a local repository. The local repository stores the future schedule received from the schedule generator before communicating the command of the future schedule to the component of the wind turbine. Since the future schedules are stored in advance, i.e. before the given time when the settings are to be implemented, any problems in communication between the schedule generator and the schedule implementation module occurring at the given time or close to the given time will not affect the working of the system for configuring the compo- nent . Moreover, a number of such future schedules corresponding to different given times may be stored in the local repository and thus the requirement of continuous and uninterrupted communication between the schedule generator and the schedule implementation module is obviated.

In another embodiment of the wind turbine configuration system, the interface is adapted to receive the weather forecast data from a weather station. Thus weather forecast data pro- vided by any weather station may be utilized.

According to a second aspect of the present technique, a method for predictably configuring a component of a wind turbine is presented. In the method comprising a set of states for the component of the wind turbine and a set of weather condition entries from a central repository are received. Each state corresponds to at least one weather condition entry. Independently of the previously mentioned step, weather forecast data including at least one predicted weather condi- tion corresponding to a given time in future is received.

Subsequently, the one predicted weather condition and the set of weather condition entries from the central repository are compared. Then, the weather condition entry corresponding to the one predicted weather condition is selected. Thereafter, the state corresponding to the selected weather condition entry is selected. Subsequently, a future schedule including at least one command corresponding to the selected state is generated. The command is adapted to initiate the setting of the component of the wind turbine to the selected state. The com- mand of the future schedule is communicated to the component of the wind turbine. Finally, and at the given time the component is set to the selected state.

Thus, according to the method of the present invention, by utilizing the weather forecast data the component of the wind turbine is predictably configured, i.e. set to a desired or selected or suitable state at a time when the weather condi- tion changes and not at a time when the weather condition has already changed.

In one embodiment of the method, the weather forecast data includes a plurality of predicted weather conditions corresponding to the given time in future and to different geographical locations. The one predicted weather condition corresponding to the given time in future and to the geographical location of the wind turbine is selected. Thus the meth- od is equipped to work with a weather forecast data of general characteristics that contains information for several geographical locations.

In another embodiment of the method, the geographical loca- tion of the wind turbine is stored in a turbine location data module before selecting the one predicted weather condition corresponding to the given time in future and to the geographical location of the wind turbine. The geographical location of the wind turbine is compared with different geo- graphical locations of the plurality of predicted weather conditions to select the one predicted weather condition corresponding to the given time in future and to the geographical location of the wind turbine. Thus, the method is equipped to monitor several wind turbines located at differ- ent geographical locations by matching the geographical location of the wind turbine to be configured as stored in the turbine location data module with the weather forecast data to select which predicted weather condition from the forecast data will be applicable to which wind turbine.

In another embodiment, the method further includes storing the future schedule in a local repository after generating the future schedule and before communicating the command of the future schedule to the component of the wind turbine. Since, a number of such future schedules corresponding to different given times may be stored in the local repository and the commands from the stored future schedules may be com- municated to the component of the wind turbine at the respective given times.

In another embodiment of the method, the weather forecast da- ta is received from a weather station. Thus weather forecast data provided by any weather station may be utilized.

The present technique is further described hereinafter with reference to illustrated embodiments shown in the accompany- ing drawings, in which:

FIG 1 is a schematic representation of an exemplary embodiment of a wind turbine configuration system; FIG 2 is a flow chart depicting an exemplary embodiment of a method for predictably configuring a component of a wind turbine; and

FIG 3 is a flow chart depicting another exemplary embodi - ment of the method for predictably configuring the component of the wind turbine, in accordance with aspects of the present technique.

Hereinafter, above-mentioned and other features of the pre- sent technique are described in details. Various embodiments are described with reference to the drawings, wherein like reference numerals are used to refer to like elements

throughout. In the following description, for purpose of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be noted that the illustrated embodiments are intended to explain, and not to limit the invention. It may be evident that such embodiments may be practiced without these specific details.

Fig 1 is a schematic representation of an exemplary embodiment of a wind turbine configuration system 1 for predictably configuring a component 5 of a wind turbine 7. The wind tur- bine 7 may be located in a wind farm 9 or a wind park 9. The component 5 of the wind turbine 7 is predictably configured by setting the component 5 of the wind turbine 7 to a state selected from a set of states. The wind turbine configuration system 1 includes a central repository 10, an interface 30, a schedule generator 50 and a schedule implementation module 70. The component 5 of the wind turbine 7 may be, but not limited to, a nacelle, a controller inside the wind turbine 7, a blade, a heating or a cooling unit inside the nacelle, a hub, and so forth.

The term 'state' or 'states', as used herein, means condition or mode of being, for example a state of the nacelle of the wind turbine 7 may be, but not limited to, 'cooled' or 'heat- ed' ; a state of the blade may be, but not limited to, 'moving' or stopped' ; a state of the heating unit may be, but not limited to, 'on' or 'off ; a state of pitch of the blade of the wind turbine 7 may be, but not limited to, 'angle of 15 degrees with direction of incoming wind' or 'edge of the blade facing incoming wind' ; a state of the hub may be, but not limited to, 'pointing into the wind' or 'moved away from direction of incoming wind'; so on and so forth.

The term, 'predictably configured' or 'predictably configur- ing' , as used herein, means setting the component 5 of the wind turbine 7 to the state selected from the set of states at a time in future when the weather condition starts to change or is changing from one condition to another condition, i.e. at a given time and not at a time when the weather condition has already changed from one condition to another condition .

For each component 5, the central repository 10 stores a set of states for the component 5 of the wind turbine 7 and a set of weather condition entries. Each state corresponds to at least one weather condition entry. The central repository 10 is a physical electronic data storage medium such as an electronic, magnetic, optical, electromagnetic, infrared, or sem- iconductor system (or apparatus or device) , and so forth. Examples of the central repository 10 include a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM) , a read-only memory (ROM) , a rigid magnetic disk and an optical disk such as compact disk-read only memory (CD-ROM) , compact disk-read/write (CD-R/W) and DVD. Table 1 shows an exemplary set of states for the component 5 of the wind turbine 7 and a set of weather condition entries.

The interface 30 is adapted to receive weather forecast data 32. The weather forecast data 32 includes at least one predicted weather condition 36 corresponding to a given time in future and to a geographical location of the wind turbine 7. Thus the one predicted weather condition 36 is the weather condition in the surroundings of the wind turbine 7 for example the weather conditions of the wind park 9. The weather forecast data 32 includes predictions of weather for a given geographical location for one or more points of times in future with respect to a time when such weather forecast data is generated or provided. The weather forecast data 32 may be provided for one or more geographical locations. The weather forecast data 32 is generated and/or provided by a weather station (not shown) . The weather station is a facility, either on land or sea, with instruments and equipment for observing atmospheric conditions to provide information for weather forecasts and to study the weather and climate . The interface 30 may be, but not limited to a port to receive data. The interface 30 may receive the weather forecast data 32 through a World Wide Web service or through other modes of communication like satellite or radio communication. The weather forecast data 32 is received by the interface 30 at a time before the given time.

The weather forecast data 32 may optionally include a plural - ity of predicted weather conditions 34,35,36,37,38 corresponding to the given time in future and to different geographical locations. The geographical locations may be provided by a coordinate system such as latitude and longitude representing a given position on the Earth's surface.

Table 2 represents an exemplary weather forecast data 32 including an example of the plurality of predicted weather conditions 34,35,36,37,38, as may be received by the interface 30.

For the purposes of explanation of Table 2, let the wind turbine 7 be located at 55 °N, 5 °W. The weather forecast data 32 corresponds to the given time, i.e. 9PM on 30/09/13 for this example. The weather forecast data 32 includes at least one predicted weather condition 36 corresponding to the given time in future and to the geographical location of the wind turbine 7, i.e. the predicted weather condition represented in serial no. 3 of Table 2.

In the wind turbine configuration system 1, the schedule generator 50 is connected to the central repository 10 and the interface 30 meaning that the schedule generator 50 exchanges, i.e. receives from and/or delivers to, information with the central repository 10 and the interface 30, and vice versa. The schedule generator 50 is adapted to compare the one predicted weather condition 36 received via the interface 30 and the set of weather condition entries (as depicted in Set A of Table 1) stored in and/or received from the central repository 10. The schedule generator 50 is also adapted to select the weather condition entry corresponding to the one predicted weather condition 36. Thus for the example depicted by Table 1 and Table 2, the schedule generator 50 compares serial no. 3 of Table 2 to Set A of Table 1, and subsequently selects the weather condition entry in serial no. 2 of Table 1, because that weather condition entry matches with the pre- dieted weather condition 36.

The schedule generator 50 is further adapted to select the state corresponding to the selected weather condition entry, and to generate a future schedule 55. The future schedule 55 includes at least one command corresponding to the selected state. The command is adapted to initiate the setting of the component 5 of the wind turbine 7 to the selected state.

In continuation of the example introduced above and depicted by Table 1 and Table 2, the schedule generator 50 selects the state from Set B of Table 1 corresponding to serial no. 2 in Table 1, i.e. the state 'Nacelle Heating on' as depicted in Table 1. Thus, the selected state is 'Nacelle Heating on' and the given time is 9PM, 30/09/13 (representing a time and a date in dd/mm/yy format, wherein 'd' is day, 'm' is month and 'y' is year) . The future schedule 55 may include the command to the effect of 'start heating unit inside the Nacelle'.

The schedule generator 50 may be, but not limited to, a pro- cessor, a controller, a PLC (programmable logic controller) , a FPGA (field-programmable gate array), and so forth. The schedule implementation module 70 is connected to the schedule generator 50 meaning that schedule implementation module 70 exchanges, i.e. receives from and/or delivers to, information with the schedule generator 50, and vice versa. The schedule implementation module 70 includes a processing element 72, for example, a processor, a controller, a PLC (programmable logic controller) , a FPGA (field-programmable gate array) , and so forth and optionally a local repository 74.

The local repository 74 is a physical electronic data storage medium such as, but not limited to, a semiconductor or solid state memory, magnetic tape, a removable computer diskette, a random access memory (RAM) , a read-only memory (ROM) , a rigid magnetic disk and an optical disk such as compact disk-read only memory (CD-ROM) , compact disk-read/write (CD-R/W) and DVD. The local repository 74 is optionally adapted to store the future schedule 55 received from the schedule generator 50 before communicating the command of the future schedule 55 to the component 5 of the wind turbine 7.

The schedule implementation module 70 is adapted to receive the future schedule 55 so generated by the schedule generator 50 and to communicate the command of the future schedule 55 to the component 5 of the wind turbine 7. The schedule implementation module 70 is further adapted to set at the given time the component 5 to the selected state.

In continuation of the example introduced above and depicted by Table 1 and Table 2, the schedule implementation module 70 receives the future schedule 55 corresponding to the selected state, i.e. the state 'Nacelle Heating on' as depicted in Table 1 and including the exemplary command to the effect of 'start heating unit inside the Nacelle'. The schedule imple- mentation module 70 then communicates the command to the effect of 'start heating unit inside the Nacelle' to the component 5 of the wind turbine 7 located at 55 °N, 5°W. Finally, the schedule implementation module 70 sets at the given time, i.e. around 9PM on 30/09/13, the component 5, i.e. the nacelle, to the selected state, i.e. 'Nacelle Heating on'.

In an exemplary embodiment of the wind turbine configuration system 1, the schedule generator 50 is adapted to select the one predicted weather condition 36 corresponding to the given time in future and to the geographical location of the wind turbine 7 from the weather forecast data 32 that includes the plurality of predicted weather conditions 34,35,36,37,38 cor- responding to the given time in future and to different geographical locations, as depicted in Table 2. The schedule generator 50 selects the one predicted weather condition 36 by comparing the geographical location of the wind turbine 7 with the different geographical locations of the weather forecast data 32. For the one predicted weather condition 36 to be selected, the geographical location of the predicted weather condition should substantially be same as the geographical location of the wind turbine 7. In another embodiment, the wind turbine configuration system

1 further includes a turbine location data module 20 connected to the schedule generator 50 meaning that turbine location data module 20 exchanges, i.e. receives from and/or delivers to, information with the schedule generator 50, and vice ver- sa. The turbine location data module stores the geographical location of the wind turbine 7. The schedule generator 50 is adapted to match the geographical location of the wind turbine 7 with different geographical locations of the plurality of predicted weather conditions 34,35,36,37,38 to select the one predicted weather condition 36 corresponding to the given time in future and to the geographical location of the wind turbine 7. The turbine location data module 20 may store the geographical location of several wind turbines 7 and/or of the wind park 9 and the wind turbine configuration system 1 may thus predictably configure one or more of the several wind turbines 7. In another embodiment of the wind turbine configuration system 1, a geographical location of the schedule generator 55 and a geographical location of the schedule implementation module 70 are same. In an alternate embodiment of the wind turbine configuration system 1, a geographical location of the schedule generator 50 and a geographical location of the schedule implementation module 70 are different. The schedule implementation module 70 may be located at the wind park 9 that includes the wind turbine 7.

FIG 2 is a flow chart depicting an exemplary embodiment of a method 1000 for predictably configuring a component 5 of a wind turbine 7. FIG 2 is explained hereinafter in combination with FIG 1. In the method 1000, in a step 100 a set of states (for example, Set A of Table 1) for the component 5 of the wind turbine 7 and a set of weather condition entries (for example, Set B of Table 1) from a central repository 10 are received. Each state corresponds to at least one weather condition entry. Independent of step 100, weather forecast data 32 including at least one predicted weather condition 36 corresponding to a given time in future is received in a step 200. The weather forecast data 32 may be received from a weather station (not shown) . In the method 1000 and subsequent to step 100 and 200, the one predicted weather condition 36 and the set of weather condition entries from the central repository 10 are compared in a step 300. Then, the weather condition entry corresponding to the one predicted weather condition 36 is selected in a step 400. Thereafter, in a step 500 the state corresponding to the selected weather condition entry is selected. Subsequently, a future schedule 55 including at least one command corresponding to the selected state is generated in a step 600. The command is adapted to initiate the setting of the component 5 of the wind turbine 7 to the selected state.

After step 600, the command of the future schedule 55 is communicated in a step 800 to the component 5 of the wind tur- bine 7. In an alternate embodiment of the method 1000, in a step 700 the future schedule 55 is stored in a local repository 74 after the step 600 and before the step 800. Finally in the method 1000, at the given time the component 5 of the wind turbine 7 is set to the selected state in a step 900 by executing the command.

FIG 3 is a flow chart depicting another exemplary embodiment of the method 1000. In this embodiment of the method 1000, the weather forecast data 32 includes a plurality of predicted weather conditions 34,35,36,37,38 corresponding to the given time in future and to different geographical locations (as depicted in Table 2) . The one predicted weather condition 36 corresponding to the given time in future and to the geographical location of the wind turbine 7 is selected in a step 260. In the selection step 260, the geographical location of the wind turbine 7 is compared with different geographical locations of the plurality of predicted weather conditions 34,35,36,37,38 to select the one predicted weather condition 36 corresponding to the given time in future and to the geographical location of the wind turbine 7. As depicted in FIG 3, in related exemplary embodiment of the method 1000, in a step 240 the geographical location of the wind turbine 7 is stored in a turbine location data module 20 before the step 260.

It may be noted that, in the turbine location data module 20 the geographical locations of several wind turbines 7 and/or the wind park 9 may be stored and the method 1000 may thus predictably configure one or more of the several wind turbines 7. The central repository 10, the local repository 74 and the turbine location data module 20 are as explained with reference to FIG 1. The set of states for the component 5 of the wind turbine 7 and a set of weather condition entries from a central repository 10 as received in step 100 and the weather forecast data 32 as received in step 200 may be received by a first processing element (not shown) that is sim- ilar to the schedule generator 50 explained in reference to FIG 1. Furthermore, the steps 300, 400, 500, and 600 may be performed by the first processing element. The steps 800 and 900 may be performed a second processing element (not shown) that is similar to the schedule implementation module 70 explained in reference to FIG 1. The first and the second processing elements may be same or may be connected to each other, i.e. the first processing element exchanges, i.e. receives from and/or delivers to, information with the second processing element, and vice versa.
