摘要:
为了解决集散式光伏发电系统光伏组串间匹配和光照差异等引起输出功率下降的问题,文章提出一种对每支光伏组串进行MPPT 控制的单组串MPPT 集散电源系统方案,实现了光伏电站发电量的最大化;针对功率转换电路,提出一种新型软开关升压变换电路拓扑,不仅能提高系统转换效率、减小设备尺寸,而且还消除了既有软开关电路拓扑在开关时序受干扰时易烧损的隐患,提高了转换电路的可靠性; 结合系统多路MPPT多转换模块的特点,提出一种载波交错同步的控制策略及其实现方法,以最大限度地抑制输出电流纹波,节省滤波器成本。通过对所试制集散电源装置进行实验,结果验证了该方案的有效性。
Abstract:
It proposed a system solution of single string MPPT converter for D&C(central distributed) PV system to solve PV strings matching problem. A ZVS soft-switching boost converter topology was proposed to improve the system conversion efficiency and reduce the device size. In addition, it eliminates the damage risk of existing soft-switching circuit topology when the switching timing is disturbed and improves the reliability of the converter. In order to suppress output current ripple and save the cost of the filter, it introduced a carrier phase interleaving synchronization strategy for power converter modules. The validity of the proposed schemes were confirmed by experimental results of prototype.
