Method of Power Generation Based on Tethered Underwater Kite System

With the continuous development of marine technology, underwater energy demand, especially in the deep sea, has become increasingly prominent. However, the existing underwater power generation methods generate insufficient output power and offer low work efficiency. To solve these problems, this paper proposes a power generation method based on a tethered underwater kite system that is suitable for low-velocity sea areas. This method significantly increases the power generation output by increasing the relative speed of the tethered underwater kite and water flow. The system has a simple and novel structure, long working hours, and high energy transformation efficiency. In this paper, the Euler-Lagrangian method is used for mathematical modeling and simulation. The simulation results show that this method can effectively solve the problem caused by the low output power of the traditional stationary water turbine power generation method in the deep sea.
