摘　　要：由于传统的光伏发电跟踪控制方法具有电机启动停止频繁、太阳辐射利用率低、系统功耗大等缺点,为此提出了一种超前滞后跟踪控制方法。该方法在每次调节过程中,使电池板法线与太阳入射光线的位置关系为超前、重合、滞后。通过仿真实验证明,在相同的跟踪时间间隔内,相比传统的跟踪控制方法,该方法能够使太阳与电池板位置的最大偏差角减小一半,因此提高了太阳辐射能量的利用。As the traditional tracking control method in the photovoltaic power has some drawbacks, including the frequent start or stop of motor, the low utilization rate of solar radiation and the big power consumption of the system.A lead-lag tracking control method in the photovoltaic power was proposed. In the process of each adjustment, the method made the position relation lead, lag or coincide between the panel normal and the sun incident ray. Through the simulation, in the same tracking interval, compared with the traditional tracking method, it is proved that the maximum deviation angle reduces by half between the sun with the position of solar panels, and increases the utilization of solar radiation energy.
