资料介绍

为了充分利用光伏发电和混合储能技术来解决无线传感器网络系统的供电电源问题,设计了以超级电容器和锂电池为混合储能装置的独立光伏供电系统。首先根据负载情况选择相应规格的超级电容器、锂电池组和光伏电池,同时采用双向DC-DC变换电路作为系统充放电主电路,并对充放电过程采用电压和电流双闭环控制。最后,利用MATLAB/Simulink对所设计的供电系统进行仿真建模与分析,仿真结果表明基于超级电容器和锂电池混合储能的光伏供电系统不仅能为无线传感器网络系统提供稳定的电源,还能有效地保护锂电池、延长其使用寿命。

To make full use of photovoltaic power generation and hybrid energy storage technology to provide power supply in the Wireless Sensor Network(WSN) system, we designed an independent power supply system with the supercapacitor and lithium battery as hybrid energy storage device. First, the supercapacitor, lithium battery and photovohaic cell of corresponding specifications were selected according to the condition of loading, then, a bi-directional DC-DC converting circuit was utilized as the main charging and discharging circuit of system, and the double closed-loop control of voltage and current was adopted in the charging and discharging process. Finally, the simulation modeling and analy...
