摘要
在传统的光伏系统最大功率点跟踪(Maximum Power Point Tracking,简称MPPT)策略中,扰动观测法通过检测系统的输入电压电流,计算其输入功率并使其达到最大。在分析光伏电池特性及数学模型的基础上,提出了一种以系统输出电流最大为目标、不依赖光伏电池输出特性检测的MPPT策略。最后,通过电流型光伏并网逆变器上和光伏充电器的实验结果,验证了该方案的可行性和正确性。
In conventional maximum power point tracking（MPPT） strategy of photovohaic system, the disturbance observation technology needs to measure the input voltage and current in order that the input power is maximized.With the analysis of characteristic and mathematic model of photovohaic cell,a MPPT strategy is proposed which aims at getting maximum output current and doesn＇t need to get the output characteristic of photovohaic cell.The experimental results of a current source PV grid-connected inverter and a PV charger show the availability and correctness of the proposed method.
