摘要
为满足在不同光照和温度条件下光伏电池的特性要求,依据光伏电池的4参数数学模型,对电池的参数进行了修正。在此基础上,在PSCAD软件中建立了封装成固有模块的光伏电池工程用仿真模型。该模型利用光伏电池在标准测试条件下得出的4个参数,考虑光照和温度的变化,模拟出光伏电池在实际工况下的输出特性。在工程仿真模型的基础上,进一步建立了光伏电池在阴影遮挡下的仿真模型,并以不同程度遮挡方式进行了带负荷仿真验证。结果表明,有无阴影遮挡的仿真模型都能够很好地模拟光伏电池的输出特性。该模型具有较好的实用性和简便性,能满足工程仿真与分析的需求。
According to the mathematical model of photovoltaic cells,a general engineering simulation model of photovoltaic cells is established in PSCAD software.The battery model utilizes the four parameters of the photovoltaic cell under standard test conditions,taking into account changes in illumination and temperature,and simulating the output characteristics of the photovoltaic cell under normal operating conditions.Based on the general engineering simulation model,the simulation model of the photovoltaic cell under the shadow occlusion is further established,and the load simulation is carried out.The simulation results show that the simulation model with or without shadow occlusion can simulate the output characteristics of photovoltaic cells under normal conditions.The model has good practicability and simplicity,and can meet the needs of engineering simulation and analysis.
