摘要
基于光伏电池的工程模型,在Matlab/Simulink中搭建仿真模型,进行输出特性的仿真,得到该光伏电池的I-V、P-V特性;光伏电池温度可根据当地的温度和光照数据得到,为了得到光伏电池在某地某一天输出最大功率的实时变化曲线,对原来的仿真模型进行了输入模块的修改,并加上光伏电池温度、环境温度、光照之间的关系模块,对修改之后的模型只需输入光伏电池的工程参数、一天的实时光照以及光伏电池在24h所对应的最大功率点电压,然后运行仿真模型,即可得到一天之内光伏电池输出的最大功率实时曲线。该仿真结果具有实用性、实时性和可观性。
A simulantion model was developed based on the engineering model under matlab/Simulink environment so as to simulate the P-V and I-V characteristics of photovoltaic cell.To get the cell's output curve of the maximum power,the input module of the original simulation model needs to be modified and then it is needed to add the modules of the cells' temperature,environment temperature and illumination.For the modified model,it is only needed to input the engineering specifications,real-time lighting and the voltage at the max power point,then the real-time output power curve varing within 24 hours is simulated
