摘要
针对电网延伸不到或电网质量不高的山区通信基站,提出了一种实用的基站供电方式,这种供电方式采用光伏电池-超级电容-燃料电池构成复合电源系统,该系统可根据不同的天气条件选择不同的电源,最大限度地发挥各自的优势,节约运行成本,确保系统稳定可靠运行。文中重点阐述了系统总体结构的设计,并详细地分析了系统的工作模式,给出了系统的控制策略。为了验证系统的有效性,在Matlab/Simulink中搭建了一种普遍的48 V/20 A通信基站电源的仿真系统,对系统进行了仿真实验,结果表明,该系统在不同外界条件下均能持续稳定可靠运行,且具备动态响应速度快、续航能力强等特点。
In light of the poor electric power quality for the communications device of mountainy base stations, a power supply mode consisted of photovohaic cells, super-capacitors and fuel cells to construct the compound power supply system is proposed. The system can automatically select the e- lectric energy supply units to ensure the system to run steadily and reliably according to the weather condition, thus giving full play to their respective advantages and saving operation cost. The design of the overall system architecture and detail analysis of the operation modes are given while a new control strategy is proposed. In order to test the performance of the system, a simulation experiment on MATLAB/Simulink is done. The results show that the system can operate sustainably, steadily and reliably under various external conditions, and is characterized by fast speed of dynamic re- sponse and strong ability of endurance.
