Description

Technical Field

[0001] This application relates to the technical field of wind power generation, and particularly to a mobile base station integrating wind power generation for an electric flying vehicle. Background Art

[0002] As a clean and renewable energy source, wind energy has been increasingly valued by countries around the world. Its reserves are huge. The global wind energy is approximately 2.74×10^9 megawatts, of which the exploitable wind energy is 2×10^7 megawatts, which is 10 times larger than the total exploitable water energy on the earth. China has a large wind energy reserve and a wide distribution area. The onshore wind energy reserve alone is approximately 253 million kilowatts.

[0003] The cost of fossil fuel power generation will become more expensive. The world energy price continues to rise, and the cost of carbon permit emissions under the carbon trading system is increasing.

[0004] However, the cost of wind power decreases with the expansion of the economic scale. Moreover, wind power generation has no fuel problems and does not produce radiation or air pollution. Therefore, wind power generation is forming a boom around the world. The general principle of wind power generation is: using the wind to drive the rotation of the windmill blades, and then increasing the rotation speed through a speed increaser to prompt the generator to generate electricity. According to the current windmill technology, a gentle breeze of 3 m / s can start generating electricity.

[0005] Traditional wind turbines installed on the ground and based on towers are a small part of global power generation, but they are currently growing rapidly. According to data released by the internationally renowned research institute REN21 supported by the government, the total power generation capacity of traditional wind turbine operators in 2011 was 238 gigawatts, which is ten times the total power generation capacity of 24 gigawatts ten years ago. Another data released by the Energy Information Administration (EIA) under the US Department of Energy shows that the total power generation capacity of various types of power generation methods globally is approximately 5000 gigawatts.

[0006] However, the wind power generation system based on tower-type traditional wind turbines has significant limitations:

[0007] a) Since the wind turbine must be as high off the ground as possible, usually, poles dozens of meters high are required to erect the system. Therefore, the production cost of a single tower-type turbine is very high, and limited by cost, its height also has a limit, and the efficiency of wind power generation cannot be further improved; b) There are serious geographical restrictions and large seasonal differences. Therefore, wind farms must be set up in areas rich in wind resources, but it still cannot guarantee wind power generation in all seasons; c) Since dozens of wind turbine power generation systems in a large area need to be connected into a control and power transmission network through underground cables, the additional cost is also very high.

[0008] Therefore, we hereby propose a mobile base station that combines an electric flying vehicle with wind power generation. Summary of the Invention

[0009] The main objective of this application is to provide a mobile base station that combines an electric flying vehicle with wind power generation, aiming to solve the problems in the prior art that the production cost of a single tower-type turbine is high, and limited by cost, its height also has a limit, and the efficiency of wind power generation cannot be further improved.

[0010] To achieve the above objective, this application provides a mobile base station that combines an electric flying vehicle with wind power generation, including: an aircraft cluster and a ground mobile base station. The aircraft cluster includes: a number of electric aircraft, as well as a wind power generation energy storage unit and an electric unit fixedly installed on the electric aircraft;

[0013] Preferably, the aircraft cluster and the ground mobile base station are connected by wireless communication, and are used to control the aircraft cluster to switch back and forth between two working modes of flying at high altitude and hovering at high altitude;

[0014] Among them, the switching of the working modes of flying at high altitude and hovering at high altitude can be controlled by a preset intelligent energy management strategy; the specific intelligent energy management strategy is: during the day, use the cruise mode to construct a strengthened air duct to improve the power generation efficiency, and at night, use the hovering mode to continuously generate electricity relying on the stable air flow formed by the atmospheric temperature difference at night.

[0016] More preferably, when the aircraft cluster adopts the high-altitude hovering mode, the aircraft cluster adjusts the output power of the electric unit according to the instructions of the flight control system, so that the rising or falling trend of the electric aircraft gradually slows down and finally reaches a relatively static state.

[0017] Preferably, the intelligent power management system includes the following steps:

[0018] S1. In the initial stage of the laser receiving and conversion system, the laser receiving mechanism periodically detects the intensity and quality of the high-energy laser beam emitted from the electric aircraft;

[0019] S2. According to the data collected in step S1, the laser beam intensity data collected in a single detection period is recorded as: I1, I2, I3... I n , and the corresponding receiving time intervals are △t1, △t2, △t3... △t n ; and the average power and energy fluctuation of the laser beam are calculated by formula (1) ; where, represents the average power of the laser beam in this detection period; represents that the energy fluctuation is equal to the ratio of the variance of the laser beam intensity data to the average intensity;

[0020] S3. Preset an energy threshold range M, and compare the energy threshold range M with the average power of the laser beam obtained in step S2;

[0021] S4. According to the judgment result of step S3, execute the corresponding control strategy; when the average power of the laser beam is lower than the energy threshold range M, the intelligent power management system will activate the energy compensation mechanism; when the average power of the laser beam is greater than the energy threshold range M, but the energy fluctuation is large, the system will activate the stability adjustment mechanism; when the average power of the laser beam is within the energy threshold range M and the energy fluctuation is within an acceptable range, the system will maintain the current laser emission state.

[0022] Preferably, the energy compensation mechanism includes the following steps:

[0023] S4-1. Based on the rated charge and discharge rate of the energy storage unit, combined with the current average power of the laser beam, calculate the initial charging current value by formula (2) ; where, V represents the rated voltage of the energy storage unit; C represents the rated charge and discharge rate of the energy storage unit; P avg represents the current average power of the laser beam;

[0028] S4-4. Calculate the deviation value between the current laser beam output power and the preset target power;

[0029] S4-5. Calculate the deviation value between the current voltage of the energy storage unit and the rated voltage;

[0030] S4-6. Adjust the charging current according to the deviation value to reduce the deviation between the laser beam output power and the energy storage unit voltage and the target values.

[0031] Preferably, the energy storage unit can be a high-performance lithium-ion battery pack or a supercapacitor.

[0032] The wind turbine adopts a vertical-axis wind turbine.

[0033] Preferably, the beneficial effects of the technical solution of the present invention are as follows:

[0034] By integrating a wind power energy storage unit, the electric aircraft can generate electricity using high-altitude wind energy during flight, which not only reduces the dependence on traditional power sources but also realizes on-site generation and immediate use of energy. The laser emitter converts electrical energy into a high-energy laser beam, effectively solving the problem of power loss during long-distance power transmission and improving the energy transmission efficiency. The laser receiving and conversion system equipped on the ground mobile base station can efficiently receive and convert these high-energy laser beams into a stable power supply, further ensuring the energy self-sufficiency of the entire system.

[0035] Compared with traditional electric aircraft or mobile base stations relying on external power sources, the mobile base station is particularly suitable for remote areas, disaster sites or environments without fixed power facilities due to the adoption of wind power generation as one of the main energy sources. The flexibility of the electric aircraft enables it to be quickly deployed to the required locations without being restricted by terrain, greatly expanding the coverage and application scenarios of the communication network. And it significantly reduces the energy consumption and maintenance costs during long-term operation.

[0036] During the day, the aircraft cluster adopts a high-altitude flight mode and flies in a circular trajectory at an angle of attack of 30°. This flight attitude combines the spiral accelerating airflow generated by the motor-driven turbine to form a conical wind wall with a diameter of up to 80 meters, thereby increasing the wind energy capture area and significantly improving the conversion efficiency from wind energy to electrical energy by strengthening the airflow channel. At night, due to the weakening of solar radiation, the temperature distribution of the atmosphere changes, forming a stable airflow. At this time, the aircraft cluster adjusts to the high-altitude hovering mode, and through the precise commands of the flight control system, adjusts the output power of the electric unit to keep the electric aircraft in a relatively stationary state. In this state, the electric aircraft can still generate electricity continuously relying on the stable airflow formed by the atmospheric temperature difference.

[0037] Through the above strategy of automatically switching the working mode according to the changes in the natural environment, it is ensured that the system can efficiently collect and convert wind energy both during the day and at night, realizing 24-hour uninterrupted energy supply.

[0044] See Figure 1 - Figure 2 , the present invention provides a mobile base station integrating wind power generation for an electric flying vehicle, including: an aircraft cluster and a ground mobile base station. The electric aircraft includes: a number of electric aircraft, and a wind power generation energy storage unit and an electric unit fixedly installed on the electric aircraft; the wind power generation energy storage unit includes: a wind turbine and a laser transmitter. The wind turbine is used to convert the wind energy in the high altitude into electrical energy, and the laser transmitter is connected to the enable terminal of the wind turbine and is adapted to convert the electrical energy into a high-energy laser beam; at least one laser receiving and converting system matching the laser transmitter is provided in the ground mobile base station.

[0045] The laser receiving and converting system includes: a laser receiving mechanism and an energy conversion module. The laser receiving mechanism includes: an optical lens array and a photoelectric converter, and is used to receive the high-energy laser beam emitted by the electric aircraft and focus it on the photoelectric converter. The energy conversion module includes a DC-DC converter and an intelligent power management system. The DC-DC converter is electrically connected to the photoelectric converter and is used to stabilize the voltage and optimize the power of the electrical energy output by the photoelectric converter to meet the power consumption requirements of different devices. The signal input end of the intelligent power management system is connected to the DC-DC converter, and the signal output end of the intelligent power management system is connected to an energy storage unit for storing and managing the converted electrical energy.

[0046] In this embodiment, by integrating a wind power generation and energy storage unit, the electric aircraft can generate electricity using high-altitude wind energy during flight. This not only reduces the dependence on traditional power sources but also enables on-site energy generation and immediate use. The laser transmitter converts electrical energy into a high-energy laser beam, effectively solving the problem of energy loss during long-distance transmission and improving the energy transmission efficiency. The laser receiving and conversion system equipped on the ground mobile base station can efficiently receive and convert these high-energy laser beams into a stable power supply, further ensuring the energy self-sufficiency of the entire system.

[0047] Meanwhile, compared with traditional fuel-powered electric aircraft or mobile base stations relying on external power sources, since wind power generation is adopted as one of the main energy sources, this mobile base station is particularly suitable for remote areas, disaster sites, or environments without fixed power facilities. The flexibility of the electric aircraft enables it to be quickly deployed to the required locations without being restricted by terrain, greatly expanding the coverage area and application scenarios of the communication network. And it significantly reduces the energy consumption and maintenance costs during long-term operation.

[0048] See Figure 3 , in one of the embodiments, the aircraft cluster and the ground mobile base station are connected by wireless communication, which is used to control the aircraft cluster to switch back and forth between two working modes: high-altitude flight and high-altitude hovering.

[0049] Furthermore, the switching between the high-altitude flight and high-altitude hovering working modes can be controlled by a preset intelligent energy management strategy or manually switched.

[0050] The intelligent energy management strategy is specifically as follows: during the day, the cruise mode is used to construct a strengthened air duct to improve the power generation efficiency, and at night, the hovering mode is adopted to continuously generate electricity relying on the stable air flow formed by the atmospheric temperature difference at night.

[0051] Among them, when the aircraft cluster adopts the high-altitude flight mode, the aircraft cluster flies along a circular trajectory at an angle of attack of 30° according to the instructions of the flight control system. The spiral accelerating air flow generated by the motor-driven turbine can form a conical wind wall with a diameter of 80 meters;

[0052] The 30° angle of attack is specifically the angle between the flight trajectory of the electric aircraft and the horizontal plane.

[0053] Specifically, when the aircraft cluster adopts the high-altitude flight mode and flies along a circular trajectory at an angle of attack of 30°, the motor-driven turbine starts to rotate at high speed. During the rotation of the turbine blades, a strong suction and acceleration effect will be exerted on the surrounding air. Due to the rotation direction of the turbine and the special design of the blades, a large amount of air is drawn into the turbine interior and, under the action of centrifugal force, is thrown out radially along the turbine. These thrown-out air forms a high-speed flowing air current, which is the initial air current source for forming the conical wind wall.

[0054] The high-speed airflow ejected from the turbine will gradually converge below the aircraft cluster due to the flight attitude of the electric aircraft and the viscosity of the air itself. As the aircraft cluster flies along a circular trajectory, this airflow is continuously supplemented and strengthened by the airflow generated by subsequent electric aircraft. At the same time, during the convergence of the airflow, due to the resistance and pressure of the surrounding air, the shape of the airflow begins to gradually change. Inside the airflow, due to the differences in airflow velocity and pressure at different positions, the rotation and convection of the airflow are caused. This rotation and convection further prompt the airflow to shape in a specific direction, that is, to spread downward and outward, gradually forming a conical structure.

[0055] With the continuous convergence and shaping of the airflow, the basic form of the conical wind wall begins to appear. At this time, the airflow velocity inside the conical wind wall is relatively large, while the airflow velocity outside gradually decreases. And a pressure gradient is formed through the above-mentioned velocity difference, making the airflow inside the conical wind wall have a certain stability. At the same time, the continuous flight of the aircraft cluster and the operation of the motor turbines continuously provide energy and airflow supplement for the conical wind wall, thus maintaining the existence and stability of the conical wind wall. In the stable conical wind wall, the velocity, pressure, and direction of the airflow show a certain regular distribution. In the area near the center and upper part of the conical wind wall, the airflow velocity is large and the pressure is small; while in the area near the edge and bottom of the conical wind wall, the airflow velocity is small and the pressure is large. Thus, the conical wind wall can effectively resist the interference of external airflow and maintain its own shape and structure.

[0056] When the aircraft cluster adopts the high-altitude hovering mode, the aircraft cluster adjusts the output power of the electric unit according to the instructions of the flight control system, so that the rising or falling trend of the electric aircraft gradually slows down and finally reaches a relatively stationary state.

[0057] In this embodiment, during the day, the aircraft cluster adopts the high-altitude flight mode and flies along a circular trajectory at an angle of attack of 30°. This flight attitude, combined with the spiral accelerating airflow generated by the motor-driven turbine, forms a conical wind wall with a diameter of up to 80 meters, thereby increasing the capture area of wind energy and significantly improving the conversion efficiency from wind energy to electrical energy by strengthening the airflow channel. And at night, due to the weakening of solar radiation, the temperature distribution of the atmosphere changes, forming a stable airflow. At this time, the aircraft cluster adjusts to the high-altitude hovering mode, and through the precise instructions of the flight control system, adjusts the output power of the electric unit to keep the electric aircraft in a relatively stationary state. In this state, the electric aircraft can still generate electricity continuously relying on the stable airflow formed by the atmospheric temperature difference.

[0058] In summary, through the strategy of automatically switching the working mode according to the changes in the natural environment, it is ensured that the system can efficiently collect and convert wind energy both during the day and at night, achieving a 24-hour uninterrupted energy supply.

[0059] In one of the embodiments, the intelligent power management system includes the following steps:

[0060] S1. In the initial stage of the laser receiving and converting system, periodically detect the intensity and quality of the high-energy laser beam emitted from the electric aircraft through the laser receiving mechanism;

[0061] S2. According to the data collected in step S1, record the laser beam intensity data collected within a single detection period as: I1, I2, I3... I n , and the corresponding receiving time intervals are △t1, △t2, △t3... △t n ; and calculate the average power and energy fluctuation of the laser beam through formula (1) ; where, represents the average power of the laser beam within this detection period; represents that the energy fluctuation is equal to the ratio of the variance of the laser beam intensity data to the average intensity;

[0062] S3. Preset an energy threshold range M, and compare the energy threshold range M with the average power of the laser beam obtained in step S2;

[0063] Specifically, when within a detection period, the average power of the laser beam is lower than the energy threshold range M, it is considered that the laser beam has a risk of insufficient energy; when within a detection period, the average power of the laser beam is greater than the energy threshold range M, it is considered that although the average power of the laser beam meets the standard, there are certain problems with the stability of its energy output; when within a detection period, the average power of the laser beam is within the energy threshold range M, send a signal of "good laser beam status" to the control center of the electric aircraft;

[0064] S4. According to the judgment result of step S3, execute the corresponding control strategy:

[0065] If the average power of the laser beam is lower than the energy threshold range M, the intelligent power management system will activate the energy compensation mechanism;

[0066] If the average power of the laser beam is greater than the energy threshold range M but the energy fluctuation is large, the system will activate the stability adjustment mechanism;

[0067] If the average power of the laser beam is within the energy threshold range M and the energy fluctuation is within an acceptable range, the system will maintain the current laser emission state.

[0068] In this embodiment, by continuously monitoring the intensity and quality of the laser beam and calculating its average power and energy fluctuations, the system can promptly detect situations of insufficient or excessive energy and take corresponding compensation measures, thereby improving the utilization efficiency of laser energy. Specifically, when a large energy fluctuation of the laser beam is detected, the system activates the stability adjustment mechanism to reduce the fluctuation by adjusting the laser emission parameters or other relevant settings, ensuring the stability of the laser beam output. When the energy fluctuation of the laser beam is detected to be small and the average power is moderate, the system maintains the current operating state to avoid unnecessary interference, thereby maintaining high-efficiency energy transmission.

[0069] In one of the embodiments, the energy compensation mechanism includes the following steps:

[0070] S4-1: Based on the rated charge-discharge rate of the energy storage unit and combined with the average power of the current laser beam, calculate the initial charging current value through Equation (2) where V represents the rated voltage of the energy storage unit; C represents the rated charge-discharge rate of the energy storage unit; P avg represents the average power of the current laser beam;

[0071] S4-2: Establish a correlation mechanism between the charging current and the average power output of the laser beam. Multiply the initial charging current value by a preset scaling factor k to obtain the real-time charging current;

[0072] S4-3: Introduce a load demand change factor α to dynamically adjust the charging current, and multiply the real-time charging current by the load demand change factor α to obtain the final dynamic charging current.

[0073] In this embodiment, by taking the rated charge-discharge rate of the energy storage unit as a reference and combining it with the average power of the current laser beam to calculate the initial charging current value (as shown in the formula), it can fully consider the characteristics of the energy storage unit itself and the power demand of the actual operation of the laser beam. This calculation method makes the initial charging current value more in line with the actual working state of the system, avoiding overcharging or over-discharging problems of the energy storage unit caused by improper charging current setting, thereby extending the service life of the energy storage unit and improving the reliability and stability of the system.

[0074] Meanwhile, multiplying the initial charging current value by a preset scaling factor k to obtain the real-time charging current enables the charging current to be dynamically adjusted according to the change in the average power of the laser beam. When the average power of the laser beam changes, the real-time charging current can respond in a timely manner to ensure that the energy storage unit can obtain an appropriate charging current under different power output conditions, maintaining the stable operation of the system. And the scaling factor k can be adjusted and optimized according to the characteristics and requirements of the specific system. For example, during the laser processing, if higher energy output stability is required, the scaling factor k can be appropriately adjusted to make the change in the charging current smoother; while in some application scenarios with higher requirements for response speed, an appropriate scaling factor k can be selected to enable the charging current to track the change in the laser beam power faster. This flexibility enables the energy compensation mechanism to meet the requirements of different application scenarios.

[0075] In addition, introducing a load demand change factor α to dynamically adjust the charging current, and obtaining the final dynamic charging current by multiplying the real-time charging current by the load demand change factor α further improves the adaptability and energy utilization efficiency of the system. That is, while improving the processing accuracy and quality of the laser system, it can also avoid energy waste caused by insufficient or excessive energy supply.

[0076] In one of the embodiments, the scaling factor k and the load demand change factor α are set in a linear relationship, and the function expression (3) α = a·k + b can be obtained; where a and b are preset coefficients.

[0077] In this embodiment, the setting of the linear relationship makes the energy compensation mechanism easier to understand and implement. In actual operation, according to the preset coefficients a and b, the value of the load demand change factor α can be quickly and accurately calculated, and then the final dynamic charging current can be determined. At the same time, it ensures that the adjustment of the charging current is smooth and stable. As the average power of the laser beam changes, the scaling factor k will change accordingly, resulting in the load demand change factor α changing according to a linear law, avoiding violent fluctuations in the charging current, reducing the impact on the energy storage unit and the laser system, and extending the service life of the equipment.

[0078] In one of the embodiments, the stability adjustment mechanism includes the following steps:

[0079] S4-4. Calculate the deviation value between the current output power of the laser beam and the preset target power;

[0080] S4-5. Calculate the deviation value between the current voltage of the energy storage unit and the rated voltage;

[0081] S4-6. Adjust the charging current according to the deviation value to reduce the deviation between the output power of the laser beam and the voltage of the energy storage unit and the target values; specifically, adjust the output energy of the energy storage unit by increasing or decreasing the charging current, thereby affecting the output power of the laser beam.

[0082] In this embodiment, by calculating the power and voltage deviation values in real time and dynamically adjusting the charging current, dual-stable control of the output power of the laser system and the voltage of the energy storage unit is achieved. This mechanism not only significantly improves the power stability, energy utilization efficiency, and dynamic response ability of the system, but also enhances the reliability and adaptability of the system.

[0083] In one of the embodiments, the wind turbine can adopt a vertical-axis wind turbine.

[0084] In one of the embodiments, the energy storage unit can be selected as a high-performance lithium-ion battery pack or a supercapacitor.

[0085] Specifically, lithium-ion battery packs are widely used in scenarios that require long-term energy storage due to their high energy density and relatively stable performance. They can provide continuous power support for electric aircraft and ground mobile base stations, especially when the wind resources are unstable or the laser emission tasks are increased, ensuring that the system will not be interrupted due to energy shortage. In addition, lithium-ion battery packs also have good charge and discharge management characteristics, and can be accurately monitored and regulated through an intelligent power management system to extend the battery life.

[0086] Supercapacitors, on the other hand, with their extremely high power density and fast charge and discharge capabilities, are an ideal choice for meeting sudden high-energy consumption demands in the system. When the laser emitter needs to output high power instantaneously, or when the electric aircraft is performing high-speed flight, climbing and other actions, the supercapacitor can quickly release a large amount of electrical energy to meet the immediate needs of the system. At the same time, when recovering braking energy or when the wind turbine generates excess electrical energy, the supercapacitor can efficiently absorb and store this energy, improving the overall energy efficiency of the system.
