摘　　要：通过对光伏阵列、最大功率跟踪进行建模和构建光伏发电系统,研究了在不同环境温度下光伏发电系统的输出特性。仿真结果表明光伏发电系统在光伏强度S=1 000 W/m2,环境温度T=50℃下的输出特性要优于其在光伏强度S=1 000 W/m2,环境温度T=25℃的输出特性。By using the photovoltaic （PV） array and a maximum power point tracking （MPPT） system, a photovoltaic power generation system was constructed and modeled. The output characteristics of the photovoltaic power generation system were studied under different temperatures. The simulation results show that the output characteristics of the power generation system with the light intensity of 1 000 W/m2 and the ambient temperature of 50 ℃ are better than that with the light intensity of 1 000 W/ms and the ambient temperature of 25 ℃.
