一种计算空间电池阵输出的新方法

在求解太阳电池阵输出的方法中，有的方法能求出输出功率，但不能求出输出电流、输出电压；有的虽能求出输出电流、电压，但未考虑太阳辐射光强对它们的影响。本文提出一种新的方法，能求出太阳电池阵工作温度、输出电流和输出电压，并考虑了太阳辐射光强的影响。该方法包括一个I-V特征关系式和一个能量平衡模型。光强和太阳电池的温度是I-V特征关系式中的变量。能量平衡模型是在稳态、忽略太阳电池的热容条件下建立的。用该种方法分析了安装在太阳能飞机上的太阳能电池阵。

A New Method for Calculating Output of Space Solar Array

Among these methods which are used to calculate output of solar array, some method can solve out power,but not current and voltage;Some can derive values of current and voltage ,but neglects the effect of solar irradiance on them.This paper puts forward a new method which can derive solar array's working temperature,output current, output voltage and considers effect of solar irradiance.The method incorporates an I-V characteristic formula and an energy equilibrium model. Solar irradiance and solar array's working temperature are variables of I-V characteristic formula. Energy equilibrium model is based on steady state and ignores specific heat of space solar array.Solar array on solar powered aircraft is analyzed with this method.
