摘　　要：针对传统的光伏阵列模型精确性不高的问题进行分析,可知影响光伏阵列模型精确性的最重要因素就是光伏电池模型的选择。对常见光伏电池模型进行分析后以单二极管模型为基础进行光伏阵列建模。通过对模型求解策略和组件标准参数的处理来提高光伏电池模型的精确性。将采用不同求解策略和标准参数建立的光伏阵列模型在matlab中进行仿真,最后再将光伏阵列模型和带有MPPT控制算法的DC-DC变换器相连接。仿真结果表明采用解方程法并利用实际计算获得的标准参数建立的模型精确性更高,且所建立的模型能与带有mppt算法的仿真界面良好连接。The accuracy of traditional PV array model is not high, after a detailed analysis shows that the most important factor affecting the accuracy of the PV array model is the choice of the PV cell model. Through the analysis of the common model of photovoltaic cells, the single diode model as the basis for PV array modeling.Through solving strategy of the model and method for getting standard parameter to improve the accuracy of the photovoltaic cell model.A photovoltaic array model which is established by using different solution strategies and standard parameters is simulated in the matlab, and then the PV array model is connected with the DC-DC converter with MPPT control algorithm.The simulation results show that the proposed model is more accurate, and the model can be well connected with the simulation interface with the MPPT algorithm.
