摘要
利用Matlab/Simulink搭建了光伏阵列数学模型,分析了传统最大功率跟踪(MPPT)方法的缺陷,针对传统电导增量法跟踪速度慢、存在误判的问题,详细研究了温度和光照强度对于光伏阵列输出特性的影响,提出新的改进电导增量法,并对核心算法进行优化,使用S函数实现了最大功率跟踪。仿真结果证明,改进后的方法能够更加快速和准确跟踪最大功率。
By using Matlab/Simulink to build a photovoltaic array mathematical model, the defects of traditional MPPT method were analyzed. And according to the problems of slow tracking speed and misjudgment existing in traditional incremental conductance method, the effects of temperature and light intensity on the output characteristic of photovoltaic array were researched. Based on which a new improved conductivity increment method was put forward, and the core of the algorithm was optimized, then the maximum power tracking was realized using S- function. Simulation results prove that the improved method can be more rapid and accurate in maximum power tracking.
