摘要
根据光伏阵列的特性和工作原理,抽象出光伏阵列的物理模型,从而给出光伏阵列的数学仿真模型。牛顿迭代法和不动点迭代法被用来求解代表光伏阵列伏安特性的超越方程。牛顿迭代法因其快速收敛而更适合用于求解光伏阵列的数学模型中超越方程。通过这个光伏阵列的数学模型,可以得到光伏阵列较为准确的伏安特性曲线。光伏阵列数学模型可以进一步应用在光伏系统的仿真当中。
According to the properties of photovoltaic arrays,an analytical simulation model for photovoltaic arrays is developed based on the DC physical model of photovoltaic module.Newton iterative method and fixed points iterative method are used to find the result of the transcendental equation.Newton iterative method can find the result faster.The precise I-V characteristics curve of photovoltaic arrays is given by the model.The analytical simulation model can be used in simulation of photovoltaic system.
