摘    要:提出了一种适用于光伏发电系统的铅酸蓄电池充电控制策略,系统采用DSP数字信号处理器,实现了最大功率点跟踪(maximumpowerpointtracking,MPPT)的充电控制。实验结果表明,本系统充分利用了光伏阵列的输出功率,缩短了过充阶段时间,提高了充电效率,克服了大多数光伏系统中蓄电池欠充的缺陷,延长了铅酸蓄电池的使用寿命。

关 键 词:光伏并网发电  零电压转换器  充电控制策略  最大功率点跟踪

Abstract:A novel lead-acid battery charge system for solar energy power generation system is presented. Based on DSP development environment, a novel MPPT algorithm is realized. According to the results of experiment, output power of photovoltaic array has been fully utilized, the time of overcharging has been shorten greatly, charging efficiency has been also improved and battery lifetime has been prolonged due to higher-level state of charge operation.
Keywords:photovoltaic grid-tied power generation ZVT-PWM charging control strategy maximum power point tracking(MPPT)
