摘　　要：针对当前光伏双轴跟踪发电系统对太阳能利用效率低的不足,在该系统中引进了一种改进的MPPT算法,将光照、温度、湿度等参数作为此系统的状态量,使系统的响应更符合实际环境变化的需求。利用MATLAB/Simulink搭建仿真系统,通过波形和数据分析比较,结果表明,引入MPPT算法的双轴跟踪系统能时刻保证光伏电池工作在最大功率点,该算法具有可行性和高效性。For the low solar utilization of photovoltaic double axes tracking system, a kind of improved MPPT algorithm was put forward. Irradiation, temperature and humidity were used as state parameters, leading the system response meet the demand for actual environment changes. The simulation system was built through MATLAB/Simulink. The results show that photovoltaic double axes tracking system based on improve MPPT algorithm can ensure that photovoltaic cells always works in the maximum power points, demonstrating the effectiveness and efficiency.
