摘　　要：在风光互补发电系统中,蓄电池作为风光互补发电系统的储能设备,在整个发电系统中起着非常重要的作用,而蓄电池充电控制方法的优劣,是影响其使用寿命的一个重要因素。文章对风光互补发电系统中蓄电池的常用充电控制方法进行了分析,提出了一种新的控制策略,即将蓄电池充电电压、充电电流采样值分别与蓄电池事先设定好的恒压过充电压、恒流充电限流值和浮充电流值进行实时比较,来判断采取哪种合理的充电方式,对蓄电池起到尽可能的保护,从而延长了风光互补发电系统中蓄电池使用寿命。As the energy storage equipment,the battery plays a very important role in the whole wind and photovoltaic hybrid power system,and the battery charging control methods is an important factor to affect its service life. In this paper, we analyzed the common battery charging control methods for the wind and photovoltaic hybrid power system, then proposed a new control strategy, which is to determine what kind of reasonable charging by compared the sampled value of the battery charging voltage and charging current with the setting value of the overcharging voltage in constant voltage phase, the limit charging current in constant current phase and the current in floating phase in real time. Then the battery is protected as far as possible, thereby prolonging the battery service life of the wind and photovoltaic hybrid power system.
