摘　　要：光伏发电是一种直接将太阳能辐射转换成为电能的新型发电技术。通过单片机C8051F020控制作用下采用正弦波脉宽调制技术(SPWM)对光伏并网发电系统进行控制,使光伏发电频率紧跟模拟电网频率,同时实现光伏最大功率跟踪,在负载变化范围内提高变换效率。Photovoltaic power generation is a new power generation technology which can directly convert solar power radiation into electric energy.The grid-connected photovoltaic power generation is controlled by using SPWM technology with the control function of single chip microcomputer C8051F020 to make photovoltaic power generation frequency follow closely with simulative power grid frequency,track maximum power point and improve convert efficiency within the load variation range.
