【摘要】 针对传统的MPPT算法无法在光伏阵列局部遮阴或光照不均等情况下对最大功率点进行有效追踪的问题,提出了一种自适应粒子群优化(APSO)算法。阐述了APSO算法的基本思想以及将该算法实际应用到光伏阵列最大功率点追踪(MPPT)追踪器中的设计思路,并给出了带APSO算法的追踪器硬件实现原理框图。测试结果表明,基于该算法的追踪器能够快速、准确地实现光伏阵列在部分遮挡条件下全局最大功率点的追踪,具有一定的工程应用价值。更多还原

【Abstract】 The traditional MPPT algorithm couldn’t solve the problem of tracking maximum power point effectively in the situation of PV array partially shaded or uneven illumination, an adaptive particle swarm optimization(APSO)algorithm was proposed. The basic idea of the algorithm and the design idea when the algorithm applied in the PV array MPPT tracker were elaborated, and the hardware block diagram of the APSO algorithm-based tracker was put forward. Test results show that the tracker can work quickly and accurately to achieve global maximum power point tracking under partially shaded conditions, and has a certain value in engineering applications.更多还原
