步进电机启动频率对太阳能发电系统效率影响

摘要

针对太阳能发电跟踪系统能耗问题，研究了步进电动机启动频率对发电效率的影响。从理论上给出其优化方法，即通过减少步进电动机启动频率可以有效提高系统发电效率。通过Matlab仿真结果表明，降低步进电动机启动频率可以降低太阳能跟踪系统本身的能耗，进而提高系统发电效率。%This article focuses on the energy consumption of the solar tracking system and studies the impact of stepper motor＇s starting frequency on the efficiency of electric power generation. Optimization methods of improving the efficiency of power generation by reducing the frequency of stepper motor＇s starting frequency is given in theory. Matlab simulation results have shown that lower starting frequency of the stepper motor can reduce the energy con- sumption of the solar tracking system itself, thereby improving system efficiency of power generation.
