Abstract

Taking the developed small, long-endurance unmanned surface vehicle as the research object, the photovoltaic power generation prediction problem of unmanned surface vehicles under wave action is studied. A simulation model of photovoltaic power generation of small-scale long-duration surface autonomous observation vehicles based on high-frequency unsteady attitude response analysis model, arbitrary slant irradiance calculation model and photoelectric conversion model is established, and the attitude response analysis model of photovoltaic panels of the observation vehicle under the real sea condition is examined by using the pool wave-making test, and the calculation model of arbitrary slant irradiance and photoelectric conversion model are examined by using the on-land rocking test device. On this basis, the typical operating conditions of the observation vehicle are sorted out, and the photovoltaic power generation of the observation vehicle under each operating condition is simulated and analyzed. The results show that： under real sea conditions, the instantaneous power fluctuation of unmanned ship photovoltaic power generation is greatly affected by the sea state, wave direction, moment and other factors, and the average power is less affected; the maximum amplitude of the power change can reach 82.5% of the average value under the three-level sea conditions, and the maximum amplitude of the power change can reach 111.8% of the average value under the four-level sea conditions.
