The safety and stability of high-voltage transmission lines face many challenges, and operation and maintenance are very difficult. Improper management can easily cause loss of life and property. Transmission line inspection is one of the most accident-prone jobs in the power system. Online inspection using tower-integrated smart cameras or sensors can view the on-site status in real time and has high inspection efficiency. However, the inspection-type electrical equipment on the tower requires continuous power supply to maintain. The existing technology often supplies power through ground wiring, which extends the wire for a long time and increases the operation and maintenance cost. There is also a part of the technology that uses photovoltaic power supply. This type of power supply method is difficult to maintain sufficient power supply in areas with insufficient light or in long-term rainy weather, and photovoltaic panels often require a large volume to provide sufficient power generation. The space on the high-altitude ultra-high voltage tower is small, and it is impossible to provide enough space to meet the installation and fixation of large-volume photovoltaic panels. For the future development of intelligent inspection of transmission lines, this patent uses wind energy and solar energy at high altitudes of towers to establish a self-powered system, in which wind turbines and photovoltaic panels jointly supply power to electrical equipment, and the wind turbines are improved so that they can adapt to the narrow environment of the tower.

[0017] Preferably, the power supply method for the photovoltaic and wind power combined power supply system of the UHV iron tower is characterized by comprising the following steps:

[0018] S1, raw data acquisition and simulation:

[0019] S101 fixes the micro wind turbine vertically to simulate the actual installation posture, and sets M DC wind turbines with different directions at equal angles around the micro wind turbine, numbered as wind direction A to wind direction M, with wind direction A being 0°;

[0020] S102, adjusting all the blades of the blinds to face the wind direction A, and presetting the angle to 0° through the encoder of the micro stepping motor;

[0021] S103, start the fan in wind direction A and set a fixed wind speed. The speed sensor on the outer surface of the support rod measures the speed of the power generation blade and feeds it back to the controller. The controller sequentially controls the micro-stepping motor to independently control the individual blades of the blinds. The specific method is as follows:

[0022] a. The micro-stepping motor rotates α degrees, and then measures the speed of the speed sensor after a delay of n seconds, and compares this speed with the previous speed:

[0023] b. When the speed increases, repeat step a above;

[0025] d. Adjust another micro stepper motor and repeat the above steps a to c until all micro stepper motors have been collected;

[0026] S104, adjusting the wind speed, collecting the rotation speed of the rotation speed sensor under different wind speeds; fitting the functional relationship between the wind speed and the rotation speed feedback from the rotation speed sensor through MATLAB, and recording the functional relationship in the database of the controller;

[0027] S105, start the wind turbines in wind directions B to M in sequence, repeat the above steps S101 to S104, and complete data collection and simulation;

[0028] S2, placing the device on a UHV tower and connecting it to electrical equipment for use; wherein the micro wind turbine is fixed vertically and the angle is preset to 0 degrees according to the method of step S1;

[0029] S3, when the micro wind turbine is blown by wind from a certain direction, the optimal wind adjustment is performed as follows:

[0032] S303, reading the information of the rotation angle β of each micro-stepping motor in the wind direction stored in the database, and adjusting the blades of the blinds to a predetermined angle;

[0033] S304, measuring the actual rotation speed of the wind speed and direction sensor at this time, and when the actual rotation speed is greater than or equal to the rotation speed read in step S302, no adjustment is performed;

[0036] S5, the energy storage module monitors the input power and output power of the system. When the input power is greater than the output power and the battery pack is fully charged, the controller adjusts the micro-stepping motor to rotate the shutters to a non-optimal wind receiving state based on the feedback, thereby reducing the input power. When the wind speed and direction sensor detects that the wind speed exceeds the dangerous threshold, the controller adjusts the micro-stepping motor to rotate the shutters to close based on the feedback, thereby preventing strong winds from damaging the power generation system. At this time, the battery pack is used for power supply.

[0037] Furthermore, on the basis of the optimal wind regulation, the maximum rotational speed under the wind direction and wind speed can be obtained, and then by multiplying the percentages, the rotational speed value of any percentage of the maximum rotational speed under the current wind direction and wind speed can be obtained, and then according to this value, the shutter blades can be further adjusted according to the adjustment method in steps S101~S105, so as to obtain the wind regulation angle of any percentage of the maximum rotational speed; for example, 75% of the maximum rotational speed, 50% of the maximum rotational speed, etc., so as to accurately meet different input power requirements.

[0039] 1. Aiming at the inconvenience of energy extraction of current power transmission tower electrical equipment and taking into account the full utilization of renewable energy, the present invention proposes a photovoltaic wind power supply system and power supply method on a high-voltage tower; the problem of continuous power supply of intelligent devices on a high-voltage tower can be effectively solved; the combined power supply method effectively solves the problem of insufficient power in a single power supply mode, and there is no need to pull wires from the ground, the cost control is excellent, and the overall device is very energy-saving;

[0040] 2. Aiming at the narrow space of the transmission tower, the present invention proposes the design of a micro wind turbine. The wind turbine adopts vertical blades, which are safe, noise-reducing, small turning radius and strong wind resistance. The outer surface of the fan adopts an adjustable shutter structure to adjust the air supply volume, and provides an optimal wind adjustment method for the shutter. Through test data and simulation to form a database, it can be quickly adjusted to the optimal wind angle according to the wind conditions in actual use. The device can also make autonomous fine adjustments in actual use, and update the adjusted data to the database, and continuously update and improve the database. After the device has been used for a period of time, the optimal wind adjustment speed will become faster and more accurate.

[0041] 3. Aiming at the impact of birds at high altitudes on the wind turbines, towers and transmission lines, the present invention proposes a new type of bird repeller. The wind-powered bird repeller generates electricity simultaneously with the wind turbine, thereby increasing the power generation of the wind turbine and improving the power generation efficiency. At the same time, it can effectively prevent the impact of birds on the wind turbine.

[0042] 4. The micro wind turbine provided by the present invention can adapt to a narrow installation environment, and can actively adjust the air intake to timely adapt to the power generation and transmission power; compared with the mode of directly adopting the opening in the shell, this shutter structure can not only perform the optimal wind adjustment, but also play the role of real-time adjustment of the wind volume according to the power situation, and can close the air outlet in special weather, such as strong wind, hail and other weather conditions, to avoid damage to the internal power generation equipment.

Adjust another micro-stepping motor (14), and repeat the above steps a to c; until all micro-stepping motors (14) are collected; S104, adjusting the wind speed, collecting the rotation speed of the rotation speed sensor (32) at different wind speeds; fitting the functional relationship between the wind speed and the rotation speed feedback from the rotation speed sensor (32) through MATLAB, and recording the functional relationship in a database of the controller (15); S105, start the wind turbines in wind directions B to M in sequence, repeat the above steps S101 to S104, and complete data collection and simulation; S2, installing the device on the UHV tower and connecting it to the electrical equipment for use; The micro wind turbine is fixed vertically and the angle is preset to 0 degrees according to step S1; S3, when the micro wind turbine is blown by wind from a certain direction, the optimal wind adjustment is performed as follows: S301, collecting angle information of the wind direction relative to 0 degrees and wind speed information through a wind speed and direction sensor (33), and collecting rotation speed information through a rotation speed sensor (32); S302, comparing the closest wind direction among wind directions A-M in the database, and reading the speed of the corresponding wind speed and direction sensor (33) under the wind direction and wind speed; S303, reading information about the rotation angle β of each micro-stepping motor (14) in the wind direction stored in a database, and adjusting the blades of the blinds (13) to a predetermined angle; S304, measuring the actual rotation speed of the wind speed and direction sensor (33) at this time, and when the actual rotation speed is greater than or equal to the rotation speed read in step S302, no adjustment is performed; S305, when the actual rotation speed is less than the rotation speed read in step S302, the position of the blades of the shutter (13) is adjusted in the same manner as in step S103; after the adjustment is completed, the wind direction, wind speed, rotation speed and rotation angle information of each micro-stepping motor (14) at this time are recorded in the database, and the database is updated; S4, the infrared sensor (4) senses the temperature information of the bird approaching; when it senses the bird approaching, the speaker continuously emits sound; when it does not sense the bird approaching, the speaker automatically emits sound at fixed intervals; S5, the electric energy storage module monitors the input power and output power of the system. When the input power is greater than the output power and the battery pack is fully charged, the controller (15) adjusts the micro-stepping motor (14) to rotate the shutter (13) to a non-optimal wind receiving state according to the feedback, thereby reducing the input power. When the wind speed and direction sensor (33) detects that the wind speed exceeds the dangerous threshold, the controller (15) adjusts the micro-stepping motor (14) to rotate the shutter (13) to close according to the feedback, thereby preventing the power generation system from being damaged by strong winds. At this time, the battery pack is used for power supply.
