摘要
为减少对传统能源的依赖,需要开发一些替代能源,因此太阳能的开发利用便应运而生。但太阳能的发电特性取决于太阳能辐射强度和环境温度,故人们提出了不同的控制算法使光伏发电系统工作在最大功率点(MPP)。这里提出一种改进的新型MPP控制算法,即分段自适应爬山法。对太阳能电动车,最大功率点跟踪器硬件电路以及改进方法的软件进行了设计。最后通过实验分析表明,与爬山法相比,分段自适应爬山法的跟踪效果较为明显。
The need for additional energy resources is increased greatly,so the conventional sources should be replace by photovoltaic(PV) energy.The performance of PV depends on solar radiation,ambient temperature.In order to achieve maximum power point(MPP) output of a PV system,different method to track the MPP has been studied.An improved MPP control algorithm,namely subsection adaptive hill climbing(SSAHC) method is proposed.The hardware and software of the maximum power point tracker are designed.In the end,compare with adaptive hill climbing method,the experimental results show that the SSAHC MPP tracker control takes on excellent performance.
