【摘要】：随着全球经济的快速发展,以及能源危机和环境污染两大问题的日益突出,新能源的开发和利用势在必行。其中,太阳能、风能和氢能的研究和应用日渐广泛,针对风能和光能内在的间歇问题以及较大的波动问题,本文提出了风光耦合制氢供电系统的供电方案,通过本供电方案可以有效地消除风电和光伏发电系统间歇性功率波动的影响,提高整体的效率。本文首先对风光耦合制氢供电系统进行了分析,其中包括太阳能、光伏发电系统、电解水制氢系统、燃料电池系统风光控制器等重要系统组成部分的构成、基本原理,并对其进行了数学模型的搭建和对各个模块容量进行了配置。在满足供给负载能量需求的基础上,根据方案中的系统工作模式,主要包括白天模式、夜间模式和连续阴雨天模式,以及各个部分的运行特点进行了监控系统的设计,对监控系统中的监测部分进行了设计与选取,其中包括电源电路、信号检测电路、模数转换电路和报警电路等进行了设计与选型,对硬件电路进行了设计,提出了针对性的能量协调控制策略。然后基于Labview软件对系统的上位机进行了设计,并对硬件电路进行了搭建,完成了下位机硬件与上位机的通信,通过测试系统整体能够成功运行。最后通过本论文的方案、设计工作以及最后的不同工作模式下的工作测试,实验结果表明系统整体可以有效地消除光风电和伏发电系统间歇性功率波动的影响,并完成满足负载要求前提下对风光耦合制氢供电系统的监测与控制的目标。虽然本论文的研究内容在实验室内完成,但是实验方案以及整体的风光耦合制氢供电监测与控制系统对以后的工程实际应用有一定的借鉴意义。
[Abstract]:With the rapid development of the global economy and the increasingly prominent problems of energy crisis and environmental pollution, the development and utilization of new energy is imperative. Among them, the research and application of solar, wind and hydrogen energy are becoming more and more extensive. Aiming at the inherent intermittent problem and large fluctuation problem of wind energy and light energy, this paper puts forward the power supply scheme of wind and solar coupling hydrogen production power supply system. The power supply scheme can effectively eliminate the impact of intermittent power fluctuations in wind and photovoltaic power generation systems, and improve the overall efficiency. Firstly, this paper analyzes the wind coupling hydrogen supply system. Including solar energy, photovoltaic power system, electrolytic water hydrogen production system, fuel cell system solar controller and other important system components, basic principles. On the basis of satisfying the energy demand of the supply load, according to the system working mode in the scheme, including the daytime mode, the mathematical model is built and the capacity of each module is configured. Night mode and continuous rainy weather mode, as well as the operating characteristics of each part of the design of the monitoring system monitoring system monitoring part of the design and selection, including the power supply circuit. The signal detection circuit, A / D conversion circuit and alarm circuit are designed and selected, and the hardware circuit is designed. Then based on the Labview software, the upper computer of the system is designed, and the hardware circuit is built, and the communication between the lower computer hardware and the host computer is completed. Through the test system as a whole can run successfully. Finally, through the project of this paper, the design work and the final work test under different working modes. The experimental results show that the whole system can effectively eliminate the impact of intermittent power fluctuations in photo-wind and volt-generation systems. And the goal of monitoring and controlling the solar coupling hydrogen supply system under the premise of satisfying the load requirements is achieved. Although the research content of this paper is completed in the laboratory. However, the experimental scheme and the whole monitoring and control system of the wind coupling hydrogen production power supply have certain reference significance for the practical application in the future.
