Abstract

Under the action of waves, a small unmanned surface vehicle (USV) will experience continuous oscillation, significantly impacting its photovoltaic power generation system. This paper proposes a USV photovoltaic power generation simulation model, and the efficiency of photovoltaic MPPT control under wave action is studied. A simulation model for solar irradiance on solar panels of USV under wave action is established based on CFD and solar irradiation models. The dynamic changes in irradiance of USV solar panels under typical wave conditions are analyzed. The MPPT efficiency of USV photovoltaic power generation devices under continuously changing irradiance conditions is studied on this basis. The simulation research results indicate that waves and solar altitude angles significantly impact the instantaneous irradiation energy of USV photovoltaic devices. However, the impact of waves on the average irradiance is relatively tiny. The sustained oscillation of irradiance poses certain requirements for the Maximum Power Point Tracking (MPPT) control frequency of USV photovoltaic systems; a disturbance control frequency of no less than 50 Hz is proposed.

小型海洋观测无人水面飞行器的光伏发电特性研究

在波浪的作用下，小型无人水面航行器（USV）会出现持续的摆动，对其光伏发电系统造成很大影响。本文提出了一种 USV 光伏发电仿真模型，并研究了波浪作用下光伏 MPPT 控制的效率。基于 CFD 和太阳辐照模型，建立了波浪作用下 USV 太阳能电池板上太阳辐照度的仿真模型。分析了典型波浪条件下 USV 太阳能电池板辐照度的动态变化。在此基础上研究了持续变化的辐照条件下 USV 光伏发电设备的 MPPT 效率。模拟研究结果表明，波浪和太阳高度角对 USV 光伏设备的瞬时辐照能量有显著影响。然而，波浪对平均辐照度的影响相对较小。辐照度的持续振荡对 USV 光伏系统的最大功率点跟踪 (MPPT) 控制频率提出了一定的要求，建议干扰控制频率不低于 50 Hz。
