| 摘 要： | 为实现太阳位置跟踪以达到提高太阳能利用率的目的,提出一种基于T-S模糊模型的太阳位置算法.该算法根据在固定地点太阳高度角随时间变化的二元函数,建立高度角为输出的T-S模糊模型,通过该模型计算出太阳的位置.该模型利用三角形隶属度函数使运算量降低,并易于实现.通过使用传统算法与基于T-S模糊模型的太阳位置算法计算出的上海临港某地4天的高度角和方位角变化曲线的对比,表明该方法具有较高的精度,能够满足普通光伏系统的要求.

| Abstract: | To realize sun position tracking so as to improve solar energy
utilization, a sun position algorithm based on T S fuzzy model is
proposed. In this algorithm, according to the binary function of the
change of the solar elevation angle at a certain position with time, a T-S fuzzy model is constructed where the output is the solar elevation
angle. Then the sun position can be calculated by the model. The triangle
membership function is used in the model to reduce the computational
burden and makes the algorithm easy to be realized. Through the comparison
of the elevation angle and azimuth angle variation curves in 4 days
respectively obtained by the traditional algorithm and the sun position
algorithm based on T S fuzzy model at a certain position of Lingang in
Shanghai, the results show that the algorithm is of higher accuracy and
can meet the requirement of the ordinary photovoltaic system. |
