摘　　要：最大功率点跟踪控制问题是光伏并网发电系统中经常遇见的问题。通过对太阳能电池板模型的建立及伏安特性、功率电压曲线的分析,对一种光伏输出侧无测量装置(PV Output Sensorless,POS)的最大功率跟踪控制方法进行了建模仿真实验,验证了该方法的可行性与正确性。在大规模的光伏发电中,这种控制方法更为安全;而且发生跟踪失败的几率较传统的MPPT算法更低,控制简单并且可靠。The Maximum Power Point Tracking is one of the key areas in PV power generation systems. A review on the model of the PV system was presented in detail, pertaining to a control strategy to the POS MPPT. Based on the analysis of the PV model and the V-I curve, the PV Output Sensorless MPPT was simulated in the MATLAB. Moreover, the control method was displayed in the table and also by the flow-process diagram. This tracking method is proved to be more reliable and flexible in the PV systems
