【摘要】：太阳能作为最重要的清洁能源之一,其产能的发展和发电效率的提升也与技术的革新息息相关。然而,现存的太阳能电站大多缺乏相对有效的监控手段。造成这一问题的原因主要是主流的监控设备存在成本高、布网复杂、应用效果单一且难以接入中、小型太阳能电站等问题。针对这些缺陷,文章基于无线传感器网络和网络控制系统模型,开展了对太阳能监控与运营管理平台的相关研究,具体研究内容和成果如下:1)提出一个太阳能监控与运营管理平台的总体架构。该架构结合了传统的太阳能监控手段和物联网的三层结构,旨在远程监控系统的同时提升系统的效率。2)根据提出的总体架构,本团队设计、研发一套相应的太阳能监控与运营维护平台的实验系统,作为一套成熟系统的雏形,其目的是为从千瓦级的家庭用户到兆瓦级的企业级用户提供一些便捷、经济及可靠的硬件和网络应用。3)针对实验系统在运行过程中遇到的实际问题,建立了相关的网络控制系统的模型,研究延时、丢包对系统稳定性所造成的影响,并给出相关优化参数;设计带有容错控制的网络控制模型,分析得出容错控制的条件,并给出证明。4)结合优化参数,对实验系统进行实地实验,验证了实验系统的可行性,从而证实了提出的总体架构的可行性。实验结果显示实验系统的自动数据提取、远程通信以及由数据驱动的网络应用等功能工作正常。相关的研究成果和技术对于太阳能的研究有很大的借鉴意义。
[Abstract]:Solar energy as one of the most important clean energy, the development of its capacity and efficiency of power generation is closely related to technological innovation. However, most of the existing solar power plants lack a relatively effective means of monitoring. The main causes of this problem are the high cost of the main monitoring equipment, complex network distribution, single application effect and difficult access, small solar power station and so on. Aiming at these defects, based on the wireless sensor network and network control system model, this paper carries out the research on solar monitoring and operation management platform. The research contents and results are as follows: 1) A solar monitoring and operation management platform architecture is proposed. This architecture combines the traditional solar monitoring method with the three-tier structure of the Internet of things, aiming to improve the efficiency of the system while remote monitoring system. 2) according to the proposed overall architecture, the team designed, To develop an experimental system for solar energy monitoring and operating and maintenance platforms, as a prototype of a mature system, designed to provide some convenience from kilowatt-class home users to megawatt enterprise-class users. Economic and reliable hardware and network applications. 3) aiming at the practical problems encountered in the operation of the experimental system, the model of the related networked control system is established, and the effects of delay and packet loss on the stability of the system are studied. The optimization parameters are given. The network control model with fault-tolerant control is designed, the condition of fault-tolerant control is analyzed, and the proof is given. 4) the feasibility of the experimental system is verified by the field experiment on the basis of the optimized parameters. The feasibility of the proposed framework is confirmed. The experimental results show that the functions of automatic data extraction, remote communication and data-driven network application work well. The related research results and technologies have great reference significance for the research of solar energy.
