In order to study the influence of altitude on the dynamic characteristics of the high-altitude kite power generation system
the high-altitude kite dynamics correction model is established based on the altitude-density-temperature-wind speed function
and the high-altitude kite dynamics simulation model based on the correction of altitude is established by combining with Simulink
so as to solve in real time parameters such as the kinematic characteristics
the flight trajectory and the power generation during the operation of the high-altitude kite. The results show that the altitude has a significant effect on the dynamic characteristics of the kite power generation system under high initial wind speed and large initial pitch angle. Under different initial wind speeds
the peak power consumption of the contraction phase of modified model increases by 7.63% to 10.02% compared with the original model
and the total energy under the same cycle increases by 15.94% to 21.61% compared with the original model
and the larger initial wind speed
the more significant impact of altitude on trajectory. under different initial pitch angles
the peak power consumption of the contraction phase of modified model increases by 4.84% to 6.63% compared with the original model
and the total energy in the same cycle increases from about 0.73% to 7.79% compared with the original model
and the larger initial pitch angle
the more significant the impact of altitude on trajectory; under different lift-to-drag ratios
the peak power consumption of the contraction phase of modified model increases from about 2.85% to 10.03% compared with the original model
and the total energy in the same cycle increases by approximately 3.96% to 15.81% compared with the original model.
