基于PV-BUS结构的最小功率点跟踪研究
Research on Least Power Point Tracking Based on PV-BUS Structure
摘要: 差分功率处理结构在提升光伏电池有效输出功率方面具有巨大的优势，变换器仅处理光伏模块之间的功率差额，就可以保证光伏阵列实现全局最大功率点跟踪。通过数学分析可以得到，在光伏–直流母线式差分功率处理结构中，差分功率变换器处理的总功率的最小功率点具有唯一性。文中所研究的最小功率点跟踪控制方法其目的是减小光伏系统中差分功率变换器处理的功率。最后在MATLAB/Simulink搭建了仿真模型进行验证，仿真结果表明集中变换器中的最小功率点跟踪与差分功率处理变换器中的最大功率点跟踪可以同时工作，有效提升系统的输出效率。
Abstract: The differential power processing structure has enormous advantages in improving the effective output power of photovoltaic cells. The converter only processes the power difference between photovoltaic modules, which can ensure that the photovoltaic array achieves global maximum power point tracking. Through mathematical analysis, it can be concluded that in the photovoltaic DC bus differential power processing structure, the least power point of the total power processed by the differential power converter is unique. The least power point tracking control method stud-ied in the article aims to reduce the power processed by differential power converters in photovol-taic systems. Finally, a simulation model was built in MATLAB/Simulink for verification. The simu-lation results showed that the least power point tracking in the centralized converter and the maximum power point tracking in the differential power processing converter can work simulta-neously, effectively improving the output efficiency of the system.
