| 摘 要： | 光伏组件输出具有非线性特性,并且其输出功率受到光照、温度等因素的影响,为了提高系统效率必要对其输出功率进行跟踪控制。首先根据光伏组件的工程模型结合组件技术参数,利用Matlab/Simlink平台建立了光伏组件的计算机仿真模型,并分析了光照、温度等因素对组件输出特性的影响,然后为了消除不利的影响和克服传统定步长功率跟踪算法的缺点,在跟踪中引入了变步长大功率跟踪算法并有效进行了仿真验证。

| Abstract: | Photovoltaic Array is nonlinear,and the power generated by it is influenced by sun light,temperature and so on.So it is necessary to track and control its output power in order to make full use of it.In this paper,firstly a simulation model is built based on Photovoltaic Array project model and its technical parameters,and the influence of sun light and temperature is also simulated.Secondly,for overcoming the disadvantage of traditional algorithms,a variable step tracking technology is introduced and its e... |
