Two paragliding kites are used to solve the problem of intermittent power generation by a single kite. The kite itself rises to 10 km, pulling the winch on the ground to generate electricity. The kite is equipped with seven kinds of sensors (GPS, humidity, temperature, air pressure, wind speed, electronic compass, gyroscope), miniature wind generator and data transmission radio station. The ground is equipped with a radio receiver, and the windward angle, posture, height and position of the kite are controlled by a computer. When the surface of the kite is perpendicular to the airflow, the kite generates the maximum tension due to wind resistance, and the kite pulls the kite control device through the rope to generate electricity through the gearbox and generator. When the rope returns in the opposite direction, the kite control device changes the angle of the windward side of the kite, so that the kite plane is almost parallel to the airflow direction, and the resistance is reduced. It is characterized in that a single kite generator outputs power intermittently, and it needs to be recovered by external energy when it returns in the reverse direction. Changing the windward angle of the kite alternately in the process of working and reverse return can produce the maximum traction and lift and make the kite climb. Two kites do work in turn. When one kite does work in the positive stroke, the other kite returns in the negative stroke. Another important function of the kite control device is to control the tension of the kite and adjust the output energy. When the wind speed is too high, reduce the windward angle (area) of the kite or adjust the height of the kite to avoid damaging the kite and generator.
