摘　　要：针对光伏电池最大功率点定位时间长的问题,提出一种基于SPICE模型的光伏电池最大功率点快速定位方案。依据构建的光伏电池SPICE模型获取了不同光照条件下功率分布数据,对功率分布数据进行二元样条插值后,利用最小二乘法对功率分布曲面进行拟合,获取了光伏电池输出功率、输出电压和环境照度的数学模型,在给定环境照度后,通过极值求取的方法实现最大功率点的快速定位。In order to solve the problems of long positioning time of the maximum power point of photovoltaic cells,a fast-positioning scheme of the maximum power point of photovoltaic cells based on SPICE model was proposed.The power distribution data under different lighting conditions were obtained according to the SPICE model of photovoltaic cells constructed.After binary spline interpolation was performed on the power distribution data,the least square method was used to fit the power distribution surface,and the mathematical model of photovoltaic cell output power,output voltage and ambient illuminance was obtained.The maximum power point can be located quickly by the method of extreme value after the ambient illumination is given.
