摘要(Abstract)：

太阳光照变化影响到太阳能路灯系统中蓄电池充电条件,弱光下光伏电池的最大功率点跟踪控制算法难以匹配蓄电池的充电要求。本文使用超级电容减小光照变化对充电条件的影响,通过推导升压变换器的最大升压比,着重分析了在弱光照情况下蓄电池的充电控制策略,并提出超级电容容量的计算方法。系统设计在保证光伏电池获得最大功率跟踪的同时,也满足蓄电池的充电要求。本文建立simulink/matlab仿真模型验证设计方法的有效性。
Changes of the Sun illumination will affect the charging conditions of batteries in photovoltaic streetlamp systems;especially in weak sunlight the maximum power point trace strategy can't follow the charging conditions' requirements.The paper proposed that using super capacitors to reduce the influence of charging conditions caused by sun light variation.and through deriving the boost convertor maximum step-up ratio,focused on analysis of weak sunlight in the case of charge control strategy and analysis of the super capacitance requirements.The design can assure the maximum power point tracing of photovoltaic panels while meeting the batteries charging requirements.The paper created the simulation model in simulink /matlab,and the simulation results verfied the feasibility of the system.
