[0002] Conventional wind power generation depends on natural wind energy and is subject to problems such as instability, low power generation efficiency, and geographical and climatic limitations. Current technology typically requires large areas of land and large blades, which are costly and difficult to maintain. The present invention solves these problems through active wind generation, an optimized wind tunnel design, and efficient energy utilization. This new energy air-to-air power generation technology is gradually emerging as an innovative method of power generation. With its unique design concept and operating principle, it enables the efficient exploitation and utilization of air energy, opening a new avenue for the development of the energy sector. Content of the invention

[0003] For this reason, the present invention proposes a new energy air-power generation system and a control method to solve the problems existing in the prior art. Specifically, the following elements are included: New energy air power generation system, characterized in that it comprises: a fan for generating a controllable airflow through an active wind generation technology; a wind tunnel module by means of which the wind flow repeatedly strikes the blades of a generator; a wind flow generator which is modularly designed, comprising at least one of a modular parallel-circuit wind tunnel, a backflow wind tunnel, a spiral flow wind tunnel, a two-parallel-two-overlap wind tunnel, a two-parallel-two-overlap backflow spiral flow wind tunnel, a two-parallel-three-overlap wind tunnel and a multi-overlap wind tunnel; an intelligent control system for real-time monitoring of a power generation state, for automatic switching of a power source and for maintaining a stable wind speed within the wind tunnel by regulating the speed of a fan or a wind tunnel rectifier device.

[0004] The inlet cut of the wind tunnel module is much larger than the diameter of the fan, and the outlet of the fan is located inside the inlet to create a siphon effect and eliminate wind tunnel resistance.

[0005] A wind flow path of the wind tunnel module, through the design of a series circuit, a parallel circuit or a return spiral flow, allows the wind tunnel to push against the generator blades two or more times in order to increase the energy utilization rate.

[0006] The diameter of the wind flux generator's blades is only 1 / 3 to 1 / 5 that of a conventional wind turbine. Its modular design facilitates assembly and maintenance. The intelligent control system includes a wind speed sensor, a fan speed control unit, and a rectifier to regulate the fan speed or blade angle in real time based on wind speed feedback, ensuring a stable wind speed within the wind tunnel.

[0007] Inventive new energy air power generation system, characterized in that the intelligent control system allows the power source to be switched automatically, the fan is driven in a primary phase by an external power source or by a diesel generator, and after stabilization of the power generation system, it switches to a wind flow power generation power source.

[0008] The following beneficial effects are achieved using the aforementioned technical solution: In the inventive new energy air-power generation system and control method, the limitation of natural wind is overcome by active wind generation; a controllable airflow is generated by means of a fan, and in combination with a siphon effect, the power generation efficiency is considerably increased; in an optimized design of a wind tunnel, a series connection, a parallel connection, an overlap, and a return-spiral flow structure are used, so that the airflow strikes the blades multiple times. The energy utilization rate is significantly increased. Through real-time monitoring of wind speed and power generation status, an intelligent control system automatically regulates fan parameters and enables seamless switching of the power source to ensure stable system operation unaffected by natural conditions. A continuous, stable power supply is provided, completely eliminating the limitations of conventional wind power generation, which is dependent on the sky. Explanation of the illustrations Fig. shows a diagram of a new energy air power generation system of the present invention. Designs

[0009] The technical solutions in the exemplary embodiments of the present invention are clearly and completely described below in conjunction with the illustrations in those embodiments. It is evident that the described exemplary embodiments are part of the exemplary embodiments of the present invention and not the entirety of the exemplary embodiments. Based on the exemplary embodiments of the present invention, all further exemplary embodiments that a person skilled in the art in the field obtains without inventive effort fall within the scope of protection of the present invention.

[0010] As in Fig.A new energy air-to-air power generation system is shown, comprising a fan, a wind tunnel module, an airflow generator, and an intelligent control system. The fan generates a controllable airflow, overcoming the limitations of natural wind. The core principle is to use the air at ground level to create negative pressure within the wind tunnel by forcing it through the fan, thus generating an airflow and enabling power generation. The fan operates on the principle of drawing in air at a negative pressure end and expelling it at a positive pressure end. When the fan diameter is significantly smaller than the inlet opening and the outlet is positioned within the inlet opening, a series of physical phenomena occur sequentially, contributing to increased power generation efficiency.The high-velocity airflow, derived from the positive pressure end of the fan, enters a relatively large inlet opening. This not only increases the air kinetic energy of the inlet area but also helps the negative pressure end overcome wind tunnel resistance. Simultaneously, the synergy of the positive and negative pressures of the fan creates a siphon effect, further contributing to the elimination of wind tunnel resistance. Additionally, the rotation of the blades of the modular wind turbine and the spiral flow wind turbine within the wind tunnel generates pressure, further enhancing the wind tunnel's ability to overcome resistance. The power generation ventilation system is finely engineered in series, parallel, overlapping, reverse flow, spiral flow, and other configurations, enabling the wind tunnel airflow to impact the impeller blades two or even more times, significantly increasing power generation efficiency.

[0011] For optimal wind tunnel design, structures such as series, parallel, overlapping, and spiral flow are used to ensure that the airflow strikes the blades multiple times, significantly increasing the energy utilization rate. 1. Wind tunnel design: The precise design of the series, parallel, and overlapping wind tunnels optimizes the path and distribution of the airflow, ensuring sufficient airflow to the generator blades. For example, a parallel wind tunnel increases the likelihood of the airflow contacting the blades, just as multiple energy channels simultaneously deliver energy to the blades. Overlapping wind tunnels increase the energy density of the airflow, resulting in more concentrated energy being delivered with each impact on the blades. 2.Inlet and outlet design: The fan outlet is located inside the inlet, and the inlet opening is significantly larger than the fan diameter. This design promotes the siphon effect, eliminates wind tunnel resistance, and simultaneously enhances the air kinetic energy of the inlet area to create a solid foundation for the subsequent power generation phase. Wind tunnel design classification: 1. A-type backflow generator: A U-shaped wind tunnel with parallel and overlapping sections is suitable. The U-shaped path ensures that the airflow repeatedly contacts the blades to increase energy capture efficiency. This design is suitable for small, distributed applications. 2.Spiral flux generator B-type: for use in an S-shaped wind tunnel in separate series connection. The spiral flux generated by the S-shaped wind tunnel allows for a more uniform and continuous force application to the blades. This type is suitable for areas with stable wind speeds. 3. Complex generator C-type: suitable for complex wind tunnel systems with single and multiple series connections, parallel connections, overlapping, reverse flow, and spiral flux. Various wind flows can be integrated, increasing the power and stability of a large integrated air generator station.

[0012] In the modular generator design, the impeller diameter is only 1 / 3 to 1 / 5 that of a conventional wind turbine generator. 1. Modular parallel-connected wind tunnel generator: A modular design is used, offering simplified assembly and maintenance. The parallel-connected wind tunnel structure allows the wind to impinge on the blades in multiple directions, effectively increasing energy capture efficiency. Modular reverse and spiral-flow wind tunnel generator: A reverse and spiral-flow design is implemented in the wind tunnel. The impingement method of the wind on the blades is modified so that the blades, at various angles and positions, more comprehensively accept the wind effect. This enhances the uniformity and continuity of the blade force, thus increasing power generation efficiency.Wind flux generator of a two-parallel-two-overlap wind tunnel: the design of the parallel connection and the overlap is combined, further increasing the wind flux energy and the number of functions applied to the blades, thus considerably increasing power generation efficiency. Return spiral flux generator of a two-parallel-two-overlap wind tunnel: based on the two-parallel-two-overlap wind tunnel, the design of the return spiral flux is combined, integrating several advantages and comprehensively optimizing power generation performance. Wind flux generator of a two-parallel-three-overlap wind tunnel and a multi-overlap wind tunnel: by increasing the number of overlaps, the wind flux energy density is further enhanced, and power generation efficiency is continuously increased.Generator of a two-parallel triple overlap and a multi-overlap reverse spiral flux: In combination with the multi-overlap and reverse spiral flux configurations, the wind flux energy is extensively utilized to enable efficient power generation, reducing manufacturing costs and maintenance difficulties. Assembly and application of the reverse flux generator: In the two-parallel wind tunnel configuration, the wind flux generator has a special construction and operating module. The wind flux generator is located in a central position within the wind tunnel, separating the two wind tunnels and serving as relative isolation and sealing. This allows force to be applied to the blades simultaneously in two wind tunnels. When the wind flux enters the wind tunnel, the blades are engaged, resulting in the initial blade engagement. If a curved wind flux or...If the blades have been subjected to backflow, they may be subjected to backflow a second time. When the wind flows past two parallel wind channels, the force is exerted on both sides of the blades simultaneously. This simultaneous force exerted on both sides results in stronger and more uniform blade dynamics, thus driving the generator's rotation more efficiently and effectively increasing power generation efficiency.

[0013] The power source is automatically switched to ensure stable system operation. 1. The principle of wind speed stability and actual factors of change: Theoretically, under certain conditions, the wind speed in the wind tunnel remains stable according to the fluid continuity equation. In practice, however, wind tunnel wall friction, local disturbances, air stickiness, temperature changes, and turbulence in the airflow can all affect wind speed stability. Wind tunnel wall friction reduces the flow velocity of the air near the wall, forming a boundary layer; disturbances in local components (such as generator blades, measuring instruments, etc.)) can change the local wind speed; air stickiness and temperature changes cause energy loss and density changes, affecting wind speed; the turbulence of the wind flow leads to random velocity pulsations. 2. Influence of wind speed changes on the components of the power generation system: A reduction in wind speed leads to a reduction in generator speed, affecting power generation output. At the same time, unstable wind speed leads to fluctuations in blade load, accelerating fatigue loss and shortening blade life. For other components within the wind tunnel, the wind flow pressure fluctuation caused by wind speed changes can lead to increased vibrations of the structure, affecting its safety and reliability. 3.Stable wind speed control strategy: An intelligent fan control system allows for real-time regulation of fan speed or blade angle based on feedback from the wind speed sensor. Within the wind tunnel, a flow control device, such as flow guide blades or grids, is installed to improve airflow characteristics. For large systems, multiple fans are controlled simultaneously, and their operating parameters are adjusted according to the wind speed at different locations within the wind tunnel to ensure a stable wind speed, increase power generation efficiency, and enhance system stability.

[0014] In this setup, the fan is driven by an external power source or a diesel generator to generate a primary airflow. 1. The principle of wind speed stability and actual factors of change: Theoretically, the wind speed in the wind tunnel remains stable under certain conditions according to the fluid continuity equation. In practice, however, wind tunnel wall friction, local disturbances, air stickiness, temperature changes, and turbulence in the airflow can all affect wind speed stability. Wind tunnel wall friction reduces the flow velocity of the air near the wall, forming a boundary layer; disturbances of local components (such as generator blades, measuring instruments, etc.)) can change the local wind speed; air stickiness and temperature changes cause energy loss and density changes, affecting wind speed; the turbulence of the wind flow leads to random velocity pulsation.

[0015] When the wind-fed power generation system successfully enters a stable operating state, the power source is automatically switched to the wind-fed power source to maintain normal operation. This automatic switching process is enabled by a sophisticated intelligent control system. The system monitors key parameters such as output power, voltage stability, and fan operating status in real time. Once the power generated by the wind-fed power generation system meets the operating requirements of the fan and the entire power generation system, the intelligent control system reacts quickly and seamlessly switches to the wind-fed power source via a dedicated switching device to ensure continuous, stable system operation.This automatic switching mechanism not only increases the autonomy and sustainability of energy use, reduces dependence on external power supply, and lowers operating costs, but also demonstrates the intelligence and efficiency of the new energy air power generation system in energy management.

[0016] The wind speed sensor and fan speed control maintain stable wind speeds within the wind tunnel. Strategy for controlling stable wind speed: An intelligent fan control system regulates the fan speed or blade angle in real time based on feedback from the wind speed sensor. A flow control device, such as flow guide blades or flow grids, is installed within the wind tunnel to improve airflow characteristics. For large systems, multiple fans are controlled together, and their operating parameters are adjusted according to the wind speed at different locations within the wind tunnel to ensure stable wind speeds, increase power generation efficiency, and enhance system stability.

[0017] By establishing an integrated model of "electricity consumption-generation-energy storage," the company achieves efficient energy cycles, significantly reducing dependence on conventional energy sources, effectively lowering energy consumption, and increasing market competitiveness. For the civilian electricity sector, this new energy airborne power generation technology means a more stable and reliable power supply. It overcomes the limitations of traditional wind power generation imposed by natural conditions, eliminating the "dependence on the sky" of daily life. It can provide residents with a sustainable and stable electricity supply, improve the quality and stability of their electricity consumption, and enhance everyday comfort. The technology's advantages are particularly noteworthy in the areas of national security strategy and the military.Military operations place high demands on energy stability, autonomy, and confidentiality. The unique characteristics of airborne power generation technology, which is not limited by the natural environment, ensure that military facilities and equipment can receive a stable power supply under various complex and extreme conditions. This not only strengthens the autonomy and flexibility of military operations but also provides robust energy security for national strategic security.
