摘　　要：从研究小型光伏发电系统需求出发,为提高软硬件开发效率及可靠性,本着硬件模块化和软件组态化的原则,设计并实现了基于推挽正激电路和实时组态环境的小型光伏模拟器。推挽正激电路可抑制直流变换器中变压器铁心偏磁及开关管两端的关断电压尖峰,而组态软件可方便构造及调整光伏阵列、光照强度、光伏阵列本体温度等模型及参数。实验结果表明,该光伏模拟器不但可较精准地模拟不同自然条件下光伏阵列的输出特性,动态响应好,达到不依赖于太阳光照而具有实际光伏阵列输出特性较理想的模拟效果,而且可使离线仿真和在线运行统一在Matlab/Simulink平台下组态和运行,调整方便、软件开发效率高。该文的工作对于实验室研究小型光伏发电具有重要参考价值。In order to meet the requirements of researching small-scale PV generation system and improve reliability and development efficiency of software and hardware, according to principle of modular hardware and eonfigurable software the PV simulator was designed and implemented based on Push-Pull Forward circuit and real-time configu- ration environment in this paper. Push-Pull Forward circuit can restrain magnetic biasing of transformer core for DC/DC converter and spike of turn-off voltage across every switch whereas configuration software can be used to conveniently construct and adjust models and parameters of PV array, sunshine intensity and PV array＇ s tempera- ture, etc. The experimental results showed that the PV simulator not only can simulate accurately static output char-acteristics of a PV array under different natural conditions and have good dynamic response so as to behave almost the same as an actual PV array, but also can be configured and run to simulate off-line and run in real-time in Mat- lab/Simulink environment, and has the merits of convenient model and parameter adjustment as well as high soft-ware development efficiency. The PV simulator presented in this paper has significant reference value for researc-hing on small-scale PV generation in laboratory.
