【摘要】 在实际工程应用中存在光伏阵列局部遮阴或光照不均等现象,导致系统输出的P-V特性曲线出现多个峰值点。为实现光伏阵列最大输出功率点的实时有效追踪,基于自适应粒子群优化(APSO)算法设计出了一种光伏阵列全局最大功率点追踪(GMPPT)控制器。简要介绍了APSO算法在控制器中的应用方法,阐述了控制器的总体设计方案及硬件电路设计,并给出了测试结果。测试结果表明:该控制器能够有效、快速、准确地追踪到光伏发电系统的全局最大功率点,具有一定的工程应用价值。更多还原

【Abstract】 Photovoltaic array partial shade and uneven illumination phenomenon were existed in the practical engineering application, which caused the P-V characteristic output curve of the system output multiple peaks. In order to track photovoltaic array maximum power output point effectively, a photovoltaic array global maximum power point tracking(GMPPT) controller was designed based on APSO algorithm. A brief description of the application of APSO algorithm was given in the controller, and the design of overall system and hardware implementation were given as well. Test results show that the tracker can work accurately and quickly to trace the global maximum power point under complex condition and has certain engineering application value.更多还原
