一种基于系绳水下风筝系统的发电方法

Method of Power Generation Based on Tethered Underwater Kite System

随着海洋技术的不断发展,针对水下尤其是深海海域中的能源需求越来越突出,而已有的水下发电方法存在输出功率不高,发电效率低等不足。针对此问题,文中提出了一种适用于低速流海域的基于系绳水下风筝系统的发电方法,该方法通过提升系绳水下风筝与水流的相对运动速度,可显著增加发电输出功率。采用欧拉-拉格朗日方法对其进行数学建模仿真,仿真结果表明,该方法可有效解决传统固定式水轮机发电方法在深海海域发电输出功率低的难题。

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.
