摘　　要：在进行现场试验时,无法在短时间内得到光伏阵列随环境变化的输出特性。为了解决这个问题,根据光伏阵列的物理模型建立了光伏阵列数学模型,并且使用Simulink软件仿真验证了模型的正确性,在此基础上,采用MSP430芯片作为主控芯片,组态王软件作为上位机软件设计了一种光伏阵列模拟器,通过输入不同的光照强度、环境温度等外部环境条件寻找工作点,控制斩波电路的输出电压,模拟不同环境条件下光伏阵列的输出特性。In the field test of photovoltaic array,the output characteristics of PV array can not be obtained in a short time. Therefore,we built a mathematical model of PV array based on the physical model of PV array. Then,we established a simulation model in Simulink and done some optimization to prove the correctness of the model. On this basis,we designed a PV array simulator with MSP430 as the main control chip and Kingview as upper monitor software. We used kingview design man-machine interface so that we can find working point when we input different light intensity,temperature and external conditions. We can control the output characteristics of the PV array simulator in different conditions by controlling the output voltage of the MSP430 chip.
