DETAILED DESCRIPTION

Reference now will be made in detail to embodiments, one or more examples of which are illustrated in the drawings. Each example is provided by way of explanation of the embodiments, not limitation of the embodiments. In fact, it will be apparent to those skilled in the art that various modifications and variations can be made in the present disclosure without departing from the scope or spirit of the invention. For instance, features illustrated or described as part of one embodiment can be used with another embodiment to yield a still further embodiment. Thus, it is intended that the present disclosure covers such modifications and variations as come within the scope of the appended claims and their equivalents.

As used in the specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the context clearly dictates otherwise. The use of the term “about” in conjunction with a numerical value refers to within 25% of the stated amount.

Example aspects of the present disclosure are directed to methods and systems that can assist in planning the placement, orientation, and/or design of wind turbine towers in a wind farm, for instance, in a computer-implemented wind farm planning tool. A wind farm can include a plurality of wind turbines. A wind turbine can have a tower. According to example aspects of the present disclosure, a tower can be divided into a plurality of circumferential sections. For example, a tower can be divided into 12, 30° circumferential sections. A determination can be made as to a load sustainment parameter for each circumferential section for a plurality of wind directions. The load sustainment parameters determined for the plurality of circumferential sections can be used in determining or planning placement, orientation and/or design of the tower in a wind farm.

In some embodiments, the tower can further be divided by evenly spaced horizontal lines to form cans. For example, a section of the tower from 0 feet to 2 feet can be a first can, a section of the tower from 2 feet to 4 feet can be a second can, and so on. In an embodiment, a determination can be made as to a load sustainment parameter for a plurality of circumferential sections of each can.

In some embodiments, loads can be determined for a plurality of different wind conditions (e.g., wind directions) for each circumferential section of a wind turbine. The determined loads of the circumferential sections can be used with a model that predicts wind conditions over a time period to simulate how the predicted wind conditions will affect the plurality of circumferential sections of the towers over the time period (e.g., the estimated life of the wind turbine tower). In some embodiments, a load sustainment parameter for a circumferential section of a tower can be determined based on the predicted wind conditions and determined loads for the time period. If the determined maximum load sustainment parameter for a circumferential section exceeds a limit, then a planned location and/or arrangement of the wind turbine can be repositioned and/or reoriented, for instance, in a computer-implemented wind farm planning tool.

As used herein, a computer-implemented wind farm planning tool can be any software or other computer implemented tool used to assist in the design of wind farms. A wind farm planning tool can, for instance, allow for a user to place wind turbine towers at various locations in a representation of a geographic area and simulate wind conditions, power generations, and other factors of the wind farm. In some embodiments, the wind farm planning tool can be used to determine loads acting on a wind turbine tower from various wind conditions according to example embodiments of the present disclosure.

The systems and methods according to example aspects of the present disclosure can have a technical effect of increasing the useful life of a plurality of wind turbines by illustrating problematic wind turbine positions and/or orientations in light of predicted wind conditions. In some embodiments, the systems and methods of the present disclosure also provide an improvement to a wind farm. For instance, the methods and systems increase the useful life of a plurality of wind turbines associated with the wind farm by placing and/or designing wind turbine towers using more accurate predictions of load sustainment from wind conditions for each circumferential section of the wind turbine tower.

For example, the systems and methods according to example embodiments of the present disclosure can determine a load for a plurality of wind conditions for a plurality of circumferential sections for a tower of a wind turbine, access a model that predicts wind conditions over a time period, determine a load sustainment parameter for the plurality of circumferential sections for the predicted wind conditions over the time period, and arrange or design a wind turbine (e.g., in a wind farm planning tool) in the wind farm based on the determined load sustainment parameter. This can allow a user to change an orientation and/or a position of a wind turbine before the wind turbine is installed and sustains damaging loads from wind. Additionally, various circumferential locations for placement of, for instance, openings (such as door openings), dents, tower shape, bolt or connections points between tower sections, and other design parameters of a wind turbine tower can be determined based on the determined load sustainment parameters for each circumferential section of the tower.

FIG. 1 depicts a wind farm 100 according to example embodiments of the present disclosure. As shown, the wind farm 100 may include a plurality of wind turbines 102, including the wind turbine 210 described below in reference to FIG. 2, and a farm controller 120. For example, as shown in the illustrated embodiment, the wind farm 100 includes twelve wind turbines, including wind turbine 210. However, in other embodiments, the wind farm 100 may include any other number of wind turbines, such as less than twelve wind turbines or greater than twelve wind turbines. In some embodiments, the controller 226 of the wind turbine 210 may be communicatively coupled to the farm controller 120 through a wired connection, such as by connecting the controller 226 through suitable communicative links 122 (e.g., a suitable cable). Alternatively, the controller 26 may be communicatively coupled to the farm controller 120 through a wireless connection, such as by using any suitable wireless communications protocol known in the art. In addition, the farm controller 120 may be generally configured similar to the controllers 226 for each of the individual wind turbines 102 within the wind farm 100.

In some embodiments, one or more of the wind turbines 102 in the wind farm 100 may include a plurality of sensors for monitoring various operational data of the individual wind turbines 102 and/or one or more wind parameters of the wind farm 100. For example, as shown, each of the wind turbines 102 includes a wind sensor 116, such as an anemometer or any other suitable device, configured for measuring wind speeds or any other wind parameter. For example, in some embodiments, the wind parameters include information regarding at least one of or a combination of the following: a wind gust, a wind speed, a wind direction, a wind acceleration, a wind turbulence, a wind shear, a wind veer, a wake, SCADA information, or similar.

Wind speeds may vary significantly across a wind farm 100. Thus, the wind sensor(s) 116 may allow for the local wind speed at each wind turbine 102 to be monitored. In addition, the wind turbine 102 may also include one or more additional sensors 118. For instance, the sensors 118 may be configured to monitor electrical properties of the output of the generator of each wind turbine 102, such as current sensors, voltage sensors, temperature sensors, or power sensors that monitor power output directly based on current and voltage measurements. Alternatively, the sensors 118 may include any other sensors that may be utilized to monitor the power output of a wind turbine 102. It should also be understood that the wind turbines 102 in the wind farm 100 may include any other suitable sensor known in the art for measuring and/or monitoring wind parameters and/or wind turbine operational data.

FIG. 2 illustrates one example embodiment of a wind turbine 210 according to example aspects the present disclosure. As shown, the wind turbine 210 generally includes a tower 212 extending from a support surface 214, a nacelle 216 mounted on the tower 212, and a rotor 218 coupled to the nacelle 216. The rotor 218 includes a rotatable hub 220 and at least one rotor blade 222 coupled to and extending outwardly from the hub 220. Each rotor blade 222 can include a pitch axis 228. For example, in the illustrated embodiment, the rotor 218 includes three rotor blades 222. However, in an alternative embodiment, the rotor 218 may include more or less than three rotor blades 222. Each rotor blade 222 may be spaced about the hub 220 to facilitate rotating the rotor 218 to enable kinetic energy to be transferred from the wind into usable mechanical energy, and subsequently, electrical energy. For instance, the hub 220 may be rotatably coupled to an electric generator (not shown) positioned within the nacelle 216 to permit electrical energy to be produced.

The wind turbine 210 may also include a wind turbine controller 226 centralized within the nacelle 216. However, in other embodiments, the controller 226 may be located within any other component of the wind turbine 210 or at a location outside the wind turbine. Further, the controller 226 may be communicatively coupled to any number of the components of the wind turbine 210 in order to control the operation of such components and/or to implement a control action. As such, the controller 226 may include a computer or other suitable processing unit. Thus, in several embodiments, the controller 226 may include suitable computer-readable instructions that, when implemented, configure the controller 226 to perform various different functions, such as receiving, transmitting and/or executing wind turbine control signals. Accordingly, the controller 226 may generally be configured to control the various operating modes of the wind turbine 210 (e.g., start-up or shut-down sequences), de-rate or up-rate the wind turbine 210, and/or control various components of the wind turbine 210. For example, the controller 226 may be configured to control the blade pitch or pitch angle of each of the rotor blades 222 (i.e., an angle that determines a perspective of the rotor blades 222 with respect to the direction of the wind) to control the power output generated by the wind turbine 210 by adjusting an angular position of at least one rotor blade 222 relative to the wind. For instance, the controller 226 may control the pitch angle of the rotor blades 222 by rotating the rotor blades 222 about a pitch axis 228, either individually or simultaneously, by transmitting suitable control signals to a pitch drive or pitch adjustment mechanism (not shown) of the wind turbine 210.

The tower 212 can be divided into circumferential sections, described in more detail below in reference to FIG. 3. In an embodiment, the tower 212 can be divided into sections by horizontal lines 230a, 230b, . . . 230n. The sections of the tower 212 defined by the horizontal lines 230a, 230b, . . . 230n can be called cans. Each can of the tower 212 can be divided into circumferential sections, as described in more detail below in reference to FIG. 3.

FIG. 3 depicts a cross-sectional view of a wind turbine tower 300 according to example embodiments of the present disclosure. The wind turbine 300 tower can have a plurality of radial boundaries 302a-302l. Two adjacent radial boundaries, such as radial boundary 302g and radial boundary 302h can define a circumferential section. Although 12 radial boundaries 302a-302l are shown, more or less radial boundaries can be used. Any number of radial boundaries can be used to determine a size of the circumferential sections. For example, 360° can be divided by the number of radial boundaries to determine an arc of each circumferential section. As a further example, when 12 radial boundaries are used, each circumferential section can have an arc of 360° divided by 12, or 30°. In some embodiments, the tower 212 can be divided into circumferential sections. In some embodiments, each can of the tower 212 can be divided into circumferential sections. As will be discussed in detail below, a load sustainment parameter can be determined for each circumferential section based on various wind conditions, such as wind direction 320.

FIG. 4 depicts a flow diagram of an example method 400 for planning a wind farm according to example embodiments of the present disclosure. The method of FIG. 4 can be implemented at least in part using, for instance, the computing system 500 of FIG. 5. FIG. 4 depicts steps performed in a particular order for purposes of illustration and discussion. Those of ordinary skill in the art, using the disclosures provided herein, will understand that various steps of any of the methods disclosed herein can be adapted, modified, rearranged, or modified in various ways without deviating from the scope of the present disclosure.

At (402), a load for a plurality of wind conditions for a plurality of circumferential sections for a tower of a wind turbine can be determined. For instance, the computing system 500 of FIG. 6 can determine a load for a plurality of wind conditions for each of a plurality of circumferential sections for a tower of a wind turbine. The plurality of wind conditions can include simulated wind from a plurality of different directions, such as 12 different wind directions about the tower. Any number of different wind directions can be used without deviating from the scope of the present disclosure.

The load for each circumferential section can be determined by determining moments resulting from the wind at the circumferential section. The moments can be in one or more directions. In some embodiments, the moments can be about a y-axis and about a z-axis associated with the wind turbine. For instance as shown in FIG. 3, moment My can be determined about a y-axis for circumferential section 310. Moment Mz can be determined about a z-axis for circumferential section 310. In some embodiments, the load can be determined for a circumferential section using the following:M(Xn)=My cos(ϕ)+Mz sin(ϕ).where ϕ is the angle of the circumferential section 310 relative to the wind direction 320.

In some embodiments, the tower of the wind turbine can be divided into a plurality of cans. For instance, the computing system 500 can divide the tower of the wind turbine into a plurality of cans. Each of the cans can include at least one horizontal boundary.

At (404) of FIG. 4, a model that predicts wind conditions over a time period can be accessed. For instance, the computing system 500 of FIG. 6 can access a model that predicts wind conditions over a time period. The model can be based on a directional Weibull model that models a frequency of wind conditions from different directions over a time period (e.g., the lifetime of the wind turbine). Based on the model, an RFC list of moments for each circumferential section can be determined. In some embodiments, the RFC list can be in the form of Markov matrices.

At (406), a load sustainment parameter for the plurality of circumferential sections can be determined for the predicted wind conditions over the time period (e.g., lifetime of the wind turbine tower). The load sustainment parameter can be a fatigue load experienced by the circumferential section over the time period. For instance, the computing system 500 can determine a load sustainment parameter for each of the plurality of circumferential sections for the predicted wind conditions over the time period. In some embodiments, determining the load sustainment parameter for the plurality of circumferential sections for the predicted wind conditions over the time period can include determining a load sustainment parameter for each circumferential section of each can.

In some embodiments, the load sustainment parameter can be calculated based at least in part on the RFC list determined using the model. In some embodiments, the load sustainment parameter can be determined as a sum of all loads over the time period taking into account of a probability of wind occurrence of the time period. The load sustainment parameter can be representative of a fatigue load for each circumferential section of the wind turbine tower.

FIG. 5 depicts a graphical representation 420 of a load sustainment parameter calculated for a wind turbine tower according to example embodiments of the present disclosure. FIG. 5 plots circumferential location on the tower along the horizontal axis and the load sustainment parameter (e.g., represented as fatigue load) on the vertical axis. As shown, the load sustainment parameter varies as a function of circumferential location on the tower.

At (408), a wind turbine in the wind farm can be arranged based on the determined load sustainment parameter. In some embodiments, arranging the wind turbine in the wind farm based on the determined load sustainment parameter can include positioning the wind turbine at a particular location in the wind farm in a computer-implemented wind farm simulation tool for planning a wind farm. In some embodiments, arranging the wind turbine in the wind farm based on the determined load sustainment parameter can include orienting the wind turbine to a particular orientation in a computer-implemented wind farm simulation tool for planning a wind farm. In some embodiments, arranging the wind turbine in the wind farm based on the determined load sustainment parameter can include physically orienting the wind turbine and positioning the wind turbine in the wind farm when installing the wind turbine tower in the wind farm.

Optionally, in some embodiments, a maximum load sustainment parameter of the determined circumferential load sustainment parameters can be determined for the plurality of circumferential sections. For instance, the computing system 500 can determine a maximum load sustainment parameter of the determined load sustainment parameters for the plurality of circumferential sections. In an embodiment, the maximum load sustainment parameter of the determined load sustainment parameters for the plurality of circumferential sections of each of the cans can be determined. For instance, the computing system 500 can determine a maximum load sustainment parameter of the determined load sustainment parameters for the plurality of circumferential sections of each can.

The maximum load sustainment parameter can be compared to a limit. For instance, the computing system 500 can compare the maximum load sustainment parameter to a limit. When the maximum load sustainment parameter exceeds the limit, the wind turbine can be rearranged in the wind farm. Rearranging the wind turbine in the wind farm can include repositioning the wind turbine in the wind farm. Rearranging the wind turbine in the wind farm can include reorienting the wind turbine. Rearranging the wind turbine in the wind farm can include reorienting the wind turbine and repositioning the wind turbine in the wind farm.

As an example and referring to FIG. 5, curve 430 can represent a design limit for a load sustainment parameter for a wind turbine tower. Curve 432 can represent a calculated load sustainment parameter for a wind turbine tower without taking into account individual circumferential loads for each circumferential section of the wind turbine tower. As shown, curve 432 exceeds the limit represented by curve 430. As a result, calculating the load sustainment parameter for the tower without regard to circumferential breakdown of the load sustainment parameter can result in a determination that a position and/or orientation of the wind turbine tower is not suitable. However, curve 420 can represent a load sustainment parameter calculated for a plurality of different circumferential sections of the wind turbine tower. As illustrated, the load sustainment parameter for the plurality of circumferential sections does not exceed the limit represented by curve 430. In that regard, when analyzing the load sustainment parameter as a function of circumferential location about the tower, the position and/or orientation of the wind turbine tower may be determined to be suitable.

Other suitable design considerations can be made based at least in part on the load sustainment parameter determined for each of a plurality of different circumferential sections of a wind turbine tower according to example embodiments of the present disclosure. For example, additional reinforcement of the tower in certain circumferential locations can be determined based at least in part on the load sustainment parameters. In some embodiments, connection points and/or positions for connecting structures (e.g., bolts) for connecting circumferential sections of a tower together can be determined based at least in part on the load sustainment parameter determined for each of a plurality of different circumferential sections of a wind turbine tower. In some embodiments, turbine operation can be optimized (e.g., yaw positions of a turbine determined during operation) based at least in part on the load sustainment parameter determined for each of a plurality of different circumferential sections of a wind turbine tower. In some embodiments, circumferential placement of one or more structures such as a tower opening (such as a door opening), duct positions, tower foundation, etc. in the wind turbine tower can be determined based at least in part on the load sustainment parameter determined for each of a plurality of different circumferential sections of a wind turbine tower. Other suitable design considerations can be implemented based at least in part on the load sustainment parameter determined for each of a plurality of different circumferential sections of a wind turbine tower without deviating from the scope of the present disclosure.

In some embodiments, operation of a controller associated with the wind turbine can be adjusted based on the load sustainment parameter. For instance, in some embodiments, load sustainment parameters computed in real time during operation of a wind turbine in a wind farm can be used to adjust, for instance, a yaw position of the wind turbine to affect load sustainment on downstream wind turbine towers.
