摘　　要：针对目前南北极考察中抛弃式设备面临的长时供电不足的问题,进行了小型风光互补供电系统中的蓄电池放电实验及风光互补供电系统的MPPT仿真,提出了极地低温环境下风光互补小型供电系统的控制策略,用仿真的方法验证了该控制策略的可行性,并针对中山站的气象环境进行了供电可靠性分析。结果表明,在极地低温严寒特殊环境下,该供电系统可靠性高,可正常工作,能够给蓄电池提供充足的电量来保证科考设备的正常工作。For the power supply shortage problem of abandoned equipment during present polar expedition, the research of battery discharging experiments and MPPT simulation for small off-grid wind-solar hybrid system was carried on. The control strategy of off-grid wind-solar hybrid system in polar low temperature environment was put forward. The feasibility of the control strategy was verified by simulation. The power supply reliability analysis of climate in Zhongshan station was carried on. These studies verify the small off-grid wind-solar hybrid system can be applied in polar environment and provide sufficient power to the battery to guarantee the normal work of scientific equipment.
