摘　　要：为提高太阳能并网发电的转换效率,课题组分析了太阳能光伏电池特性,构建了数学模型,研究了温度和光照强度变化时输出特性,据此搭建了并网发电的结构。采用扰动观察法进行光伏并网发电的最大功率点跟踪(MPPT)设计,通过MATLAB仿真分析表明,输出功率能够自动跟踪光照强度的变化,可以确保太阳能并网发电系统高效率、安全稳定地运行。In order to improve the conversion efficiency of solar grid connected power generation,the research group analyzes the characteristics of solar photovoltaic cells,constructs a mathematical model,and studies the output characteristics when the temperature and illumination intensity change.And based on this,a grid-connected power generation structure was built.The maximum power point tracking(MPPT)of photovoltaic grid connected power generation is design by the disturbance observation method.MATLAB simulation analysis shows that the output power can automatically track the change of light intensity,which can ensure the efficient,safe and stable operation of the solar grid-connected power generation system.
