Description

Technical Field

[0001] The present invention belongs to the technical field of wind energy prediction, and more specifically, relates to a device and a measurement method capable of measuring wind energy all-weather. Background Art

[0002] Existing wind measurement technologies only use a ground-based wind measurement tower alone, or use an unmanned aerial vehicle (UAV) to conduct measurements in a region, or use a meteorological balloon to stay in the air for a long time. The meteorological data measured has defects brought by being single and technical limitations. Among them, the meteorological balloon changes with the wind relative to a fixed position on the ground and cannot measure meteorological data at various given heights and different given positions. The construction cost of a single wind measurement tower is relatively high, the installation is complex, and it also needs to be repeatedly built. When measuring the wind speed of a wind field, this process is rather cumbersome and requires a large amount of additional time cost and economic cost. Although the UAV can measure meteorological data at various given heights and different given positions, its battery power is limited and it cannot measure the target region for a long time, nor can it measure the target region all-weather. Therefore, how to achieve all-weather measurement of wind energy, obtain more perfect and accurate meteorological data, and be able to reduce the investment cost of measuring wind resources, and avoid the defects of the meteorological data measured by the existing wind measurement system due to the single measurement method and measurement technology limitations is an urgent problem to be solved.

[0044] The present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0045] As Figure 1 shown, an all-weather wind energy measurement device according to the present invention includes:

[0046] A first meteorological measurement unit for all-weather measuring the wind speed and wind direction at the vertex of the first meteorological measurement unit at a set measurement point in a target wind field to obtain first meteorological data;

[0047] A second meteorological measurement unit for measuring the wind speed and wind direction at a plurality of set heights in the longitudinal direction at the set measurement point to obtain second meteorological data; the heights at the plurality of set heights are all higher than the vertex height of the first meteorological measurement unit; the second meteorological data is used to correct the first meteorological data;

[0048] A data processing unit for storing and analyzing all the first meteorological data and the corresponding all the second meteorological data at all set measurement points in the target wind field to predict the wind energy of the target wind field.

[0049] Specifically, the present invention measures the wind speed and wind direction at a fixed height of a set measurement point in a target wind farm through a first meteorological measurement unit to obtain first meteorological data. The first meteorological measurement unit is arranged in the upwind direction of a preset fan position in the target wind farm. The ground height of the set measurement point is lower than the blade height of the preset fan, and the height of the first meteorological measurement unit is lower than the blade height of the preset fan. The measurement module of the first meteorological measurement unit is arranged at the vertex of the first meteorological measurement unit to ensure that the wind speed and wind direction measured by the first meteorological measurement unit can provide data support for the site selection of the preset fan. The first meteorological measurement unit adopts a structure that is easy to install and remove, enabling it to quickly and conveniently transfer to the next measurement point for measurement after completing the measurement of one measurement point, improving the measurement efficiency while reducing costs. Then, the second meteorological measurement unit measures the wind speed and wind direction at different heights above the first meteorological measurement unit longitudinally to obtain second meteorological data. To ensure accurate measurement of the wind speed and wind direction at different heights and set positions, an unmanned aerial vehicle (UAV) carrying a wind speed and wind direction sensor is generally used for measurement. The UAV hovers at the set height and set position to measure the wind speed and wind direction at that position. However, due to the limited battery life of the UAV and its inability to support all-weather measurement, it can only measure short-term meteorological data, and the second meteorological data it measures is used to correct the long-term data measured by the first meteorological measurement unit. The data processing unit analyzes all the first meteorological data and the corresponding second meteorological data of all set measurement points in the target wind farm to predict the wind energy of the target wind farm, that is, analyzes all the first meteorological data and the second meteorological data of a certain measurement point to predict the wind energy of that measurement point. After predicting the wind energy of all measurement points, comprehensively analyze and compare the wind energy of each measurement point, and select the most suitable position for installing the fan in combination with factors such as the specifications and models of the preset fan and the geological conditions of the target wind farm. By measuring the wind speed and wind direction at different heights and different time periods through the first meteorological measurement unit on the ground and the second meteorological measurement unit in the air respectively, the data error caused by only using a ground anemometer tower or a UAV alone for measurement is reduced. When only a ground anemometer tower is used for measurement, the wind speed in different height directions cannot be measured. When only a UAV is used for measurement, the UAV cannot stay in the air for a long time and cannot measure long-term meteorological data. If the two measurement methods are combined, the data obtained can reduce the respective defects of the two methods.

[0050] In one example, the first meteorological measurement unit includes:

[0051] A first measurement module, arranged at the top of the support and fixation module, for measuring the wind speed and wind direction at the top of the support and fixation module;

[0052] A support and fixation module, for supporting the first measurement module and fixing the first measurement module at the top of the support and fixation module;

[0053] The support and fixation module is fixedly installed at a set measurement point, which is set in the upwind direction of the preset wind turbine position in the target wind farm. The ground height of the set measurement point is lower than the blade height of the preset wind turbine, and the vertex height of the support and fixation module is lower than the blade height of the preset wind turbine.

[0054] Specifically, the first meteorological measurement unit includes a first measurement module and a support and fixation module. The first measurement module is fixedly installed at the top of the support and fixation module, and the support and fixation module is fixedly installed at a set measurement point, which is set in the upwind direction of the preset wind turbine position in the target wind farm. The ground height of the set measurement point is lower than the blade height of the preset wind turbine, and the vertex height of the support and fixation module is lower than the blade height of the preset wind turbine. By measuring the wind speed and direction at the top of the support and fixation module at this measurement point, the wind force obtained by the wind turbine blades at this height at the preset wind turbine position can be predicted, that is, the wind energy that the preset wind turbine can utilize, so as to select a location for the preset wind turbine.

[0055] In one example, the second meteorological measurement unit includes:

[0056] A second measurement module, fixed on the flight module, for measuring the wind speed and direction at multiple set heights longitudinally at the set measurement point;

[0057] A flight module, for carrying the second measurement module to fly to multiple set heights for measurement work.

[0058] Specifically, the second meteorological measurement unit includes a second measurement module and a flight module. The second measurement module is fixed on the flight module, such as a drone. By flying the flight module to different set heights above the top height of the first meteorological measurement unit longitudinally at the set measurement point, the wind speed and direction at different set heights are measured. However, due to technical limitations, the flight duration of the flight module is limited and it can only measure in the short term and cannot measure all-weather, and there will be errors in the measured data, which is used to correct the long-term data measured by the second meteorological measurement unit in the present invention; the flight module can choose a drone or other flight devices that can hover at set heights and positions, but it is not recommended to use a meteorological balloon because the balloon changes with the wind relative to the fixed position on the ground and does not have the ability to measure the wind speed and direction at various heights and different positions.

[0059] In one example, the data processing unit includes:

[0060] A data analysis module, for analyzing all the first meteorological data and the corresponding all second meteorological data at all set measurement points in the target wind farm to predict the wind energy of the target wind farm;

[0061] A data storage module, for storing all the first meteorological data and the corresponding all second meteorological data at all set measurement points.

[0062] Specifically, the data processing unit includes a data analysis module and a data storage module. The data analysis module analyzes all the first meteorological data and the corresponding second meteorological data at each set measurement point, predicts the wind energy at each set measurement point, and further predicts the wind energy of the target wind farm. It decides whether to build a wind power station based on the wind energy of the target wind farm and determines the installation position of the wind turbines according to the wind energy at each set measurement point. The data storage module stores all the first meteorological data and the corresponding second meteorological data at all set measurement points.

[0063] In one example, the support and fixation module is a wind speed tower that is easy to install and disassemble. The wind speed tower includes:

[0064] A fixed base, horizontally fixed on the ground, used to fix the wind speed tower to the ground;

[0065] A support column, vertically fixed on the fixed base, used to support the first measurement module;

[0066] A flange plate, fixed at the top of the support column, used to fix the first measurement module.

[0067] Specifically, the support and fixation module is a wind speed tower that is easy to install and disassemble, consisting of a fixed base, a support column, and a flange plate. The fixed base, support column, and flange plate are fixedly connected, such as connection methods like welding and bolt connection. This wind speed tower can be repeatedly disassembled and reused, and is easy to measure wind speed and wind direction at different measurement points. The wind speed tower is fixed to the ground through the fixed base. For convenient disassembly, it can be chosen to fix the fixed base to the ground with bolts. The first measurement module is fixed to the flange plate at the top of the wind speed tower through bolts, and thus fixed to the wind speed tower to measure the wind speed and wind direction at the vertex height of the wind speed tower. Other methods can also be adopted to fix the first measurement module to the wind speed tower, not limited to the installation method proposed in the present invention. For example, an installation platform can be set on the side of the wind speed tower, and the first measurement module is fixed on the installation platform for measurement. If the wind speed tower is relatively high, for convenient disassembly, the support column can be composed of multiple sections of support columns spliced together, and the splicing method adopts bolt connection.

[0068] In one example, the first measurement module includes:

[0069] A wind speed and wind direction sensor.

[0070] In one example, the flight module includes:

[0071] A load-carrying unmanned aerial vehicle, used to transport the second measurement module fixed to the load-carrying unmanned aerial vehicle to multiple set heights longitudinally at the set measurement point for measurement.

[0072] In one example, the second measurement module includes:

[0073] An airborne wind speed and wind power sensor.

[0074] In one example, it further includes:

[0075] A communication module for the first meteorological measurement unit and the second meteorological measurement unit to communicate with the data processing unit respectively.

[0076] Specifically, in the present invention, the measurement data of the first meteorological measurement unit and the second meteorological measurement unit are transmitted to the data processing unit through the communication module, and the communication can be carried out by means of wireless communication or wired communication.

[0077] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, but it is not intended to limit the present invention. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0078] Embodiment 1

[0079] This embodiment provides an all-weather wind energy measurement device for the development of wind power. First, the wind resources in the area need to be evaluated to accurately grasp the characteristics of the wind resources in the area and provide necessary data support for the subsequent wind data measurement. Then, a large-scale wind measurement tower or lidar is established. The existing wind measurement methods have relatively long construction periods and high construction costs, and there are relatively large defects, including:

[0080] As Figure 2 shown, the ground measurement unit includes a wind measurement tower and a ground wind speed and direction sensor. The height of the wind measurement tower is below the wind turbine blades, and its top is connected to the ground wind speed and direction sensor through a flange. The ground wind speed and direction sensor can be a propeller-type sensor, a three-cup sensor or an ultrasonic sensor; the ground measurement unit can continuously measure meteorological data such as wind speed and direction at a fixed height above the ground at a preset measurement point in the target wind farm near the position of the preset wind turbine; when measuring the wind speed, first use a simple portable anemometer to measure the approximate wind direction, and then in front of the wind turbine, a wind measurement tower is arranged at a ground height lower than the height of the wind turbine blades to weaken the influence caused by the boundary layer formed by the wind passing through the wind turbine blades and the blade gas wake, monitor the near-ground wind speed and direction, arrange a wind speed sensor at the top of the wind measurement tower, and use a flange to connect and fix the wind speed sensor, and adjust the sensor position in a timely manner according to different wind speeds and directions to measure long-term meteorological data such as wind speed and direction and obtain continuous meteorological data;

[0081] As Figure 3As shown in the figure, the airborne UAV measurement unit includes a load-carrying UAV and an on-board UAV wind speed and direction sensor. The on-board UAV wind speed and direction sensor is fixedly installed above the load-carrying UAV. This UAV can measure meteorological data such as wind speed and direction at different height positions above the ground-based wind measurement tower in the target wind field. However, due to the problem of being unable to stay in the air for a long time, it cannot measure the wind speed at high altitudes locally for a long time and can only measure short-term meteorological data for correcting the long-term data measured on the ground. Currently, UAVs can be deployed quickly and have high monitoring efficiency. They can flexibly select monitoring directions and paths to obtain highly spatially resolved localized data, making them ideal vehicles for the atmosphere and meteorological monitoring system. First, deploy a UAV above the selected wind measurement tower position, install a lightweight ultrasonic wind speed and direction sensor above the UAV and equip it with a storage battery to supply power to the ultrasonic wind speed and direction sensor, or use a propeller-type sensor, a three-cup sensor, or use an integrated meteorological UAV system with a wind speed and direction detection module to measure meteorological data at different directions, heights, and positions above the measured wind field. During the measurement process, it is also required that the aircraft stay hover as much as possible, stay in the air facing the wind direction, and avoid changes in flight attitude. Second, conduct meteorological data measurement and collection at positions where other wind measurement towers in the wind field cannot measure, and transmit the measured meteorological data such as wind speed and direction to the ground data analysis system to obtain more comprehensive data, which can supplement and correct the overall meteorological environment of the wind field, and can more realistically predict the power characteristics of wind power generation after installing a wind power station in this wind field. However, due to the insufficient endurance of the UAV, there are discontinuities in the measurement time.

[0082] The data analysis and storage unit includes a storage module and a data processing module. After the ground sensors and airborne sensors complete the measurement, they transmit the meteorological data to the data processing module. This data processing module analyzes and compares the meteorological data from both the ground and the air received, and stores the data. The data can be stored through a data recorder, a USB flash drive, a mobile hard disk, etc.

[0083] As Figure 4As shown in the figure, the wind speed and direction are measured at different heights and different time periods from both the ground and the air, reducing the data error caused by only measuring with a ground anemometer tower or a drone alone. When only the ground anemometer tower is used for measurement, the wind speed in different height directions cannot be measured. When only the drone is used for measurement, the drone cannot stay in the air for a long time and long-term meteorological data cannot be measured. If the two measurement methods are combined, the data obtained can reduce the respective defects of the two methods; the wind measurement device of the present invention has a considerable degree of flexibility, can be repeatedly disassembled and reused to measure at different heights at various positions within the wind measurement area, reducing the investment cost of measuring wind resources, and avoiding the defects brought by the single and technical limitations of the meteorological data measured by the previous wind measurement system; it improves the flexibility of the layout of the wind measurement system, and after the data measured by the drone is used to correct the ground measurement data to a certain extent, the accuracy of the measurement data is improved.

[0084] Embodiment 2

[0085] As Figure 5 shown, this embodiment provides an all-weather wind energy measurement method, which is applied to the all-weather wind energy measurement device described in any one of Embodiment 1, and includes:

[0086] The ground measurement unit measures the wind speed and direction at the apex of the anemometer tower at the set measurement point in the target wind farm all-weather to obtain the first meteorological data;

[0087] The aerial drone measurement unit measures the wind speed and direction at multiple set heights longitudinally at the set measurement point to obtain the second meteorological data; the heights of the multiple set heights are all higher than the apex height of the anemometer tower; the second meteorological data is used to correct the first meteorological data;

[0088] The data analysis and storage unit analyzes all the first meteorological data and the corresponding all second meteorological data of all the set measurement points in the target wind farm to predict the wind energy of the target wind farm, and stores all the first meteorological data and the corresponding all second meteorological data.

[0089] The above has described the embodiments of the present invention. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments.
