摘要
介绍了一种新型家用双向控制的太阳能发电系统实验装置。采用CUK电路作为太阳能发电系统DC/DC单元的主回路,对其基本电路进行了研究。在分析模糊逻辑技术的原理基础上,研究了模糊控制的最大功率跟踪法,以实现太阳能电池最大功率点的跟踪、控制。另外对太阳能发电系统中的逆变器进行了探讨,通过小信号分析法得出系统电压和电网电流的数学模型,并设计出使系统稳定的控制方案。最后通过研制出的太阳能发电系统与电力系统联网运行,大量的实测数据显示该系统的节能效果达30%。
A new home solar energy generator system of double direction control is introduced. Adoption CUK circuit by way of main- loop for its DC/DC, its base circuit is researched. Based on analyzing the pfineiple of fuzzy logic technique, the most power scout method of fuzzy control is studied for realizing to scout and control for solar cell most power dot. In addition, the inverter of solar energy generator system is discussed. Through small signal analytical method the math model of system voltage and power system current is obtained, and the system steady control project is designed. Finally, the solar energy generator system is connected to the power system with circulated function, and a great deal of measure data show its energy saving effect could be 30%.
