【摘要】：发展新能源及可再生能源是推动世界新一轮经济增长的引擎之一,构建智能电网,形成以电为中心的能源配置体系,是推进能源绿色低碳发展、保障能源可持续供应的必由之路,是未来社会发展的重要保障。本文面向国家奥林匹克体育中心现有条件,开展智能微电网的规划设计,旨在推动合理利用光伏发电技术、储能技术和依托通讯信息系统的自动化技术的应用,提升奥体中心绿色、高效、优质的供用电水平。本文针对国家奥林匹克体育中心进行智能微电网的规划设计,重点从以下四个方面进行了研究：智能微电网规划设计的总体方案、光伏发电系统的设计、储能系统的设计、微电网配电自动化系统的设计。首先说明了网架结构设计、光伏发电设计、储能设计、智能配电设计4个子专业的方案设计要点,经过网架结构方案的比选,确定了采用双射网(开闭所)的供电方案。同时,对整个网架结构进行了各部分的设计说明,完成了智能微电网规划设计的总体方案。然后,通过对比分析三种不同的光伏配置方案,选择出适合本设计的最佳方案,即分散式光伏设置、就地接入方案。以英东游泳馆为例,充分考虑到室外电动汽车充电的需要,设计了配合电动汽车充电的光伏发电系统,包括光伏发电系统结构、主要技术特点概括以及电动汽车充电的电气回路设计等,最后讨论了光伏发电系统的发电功率预测问题,从而完成了整个光伏发电系统的设计。其次,分析了各种储能设备的特性,通过对比分析,最终确定采用液流电池作为智能微电网的集中储能方案,并完成了储能系统的总体设计。最后,详细阐述了设计的微电网能量管理系统的主要功能和体系结构,将配电系统分成三个层次结构：系统主站层、系统子站层、系统终端层,并给出了各层的主要功能,实现了整个配电自动化系统框图的总体设计。本文设计案例充分展示现代信息、新材料技术、储能技术和新的电网结构等给电网带来的巨大变化,奥体中心各个环节的优化与自适应自动控制,园区电网将是一个更加安全、可靠、清洁、高效、经济的智能微电网,这带来了良好的示范效应,对于微电网的推广,绿色能源、节能减排等理念的普及起到引领作用。
[Abstract]:The development of new energy and renewable energy is one of the world to promote a new round of economic growth engine, the construction of smart grid, the formation energy allocation system to power as the center, is to promote the green energy low-carbon development, guarantee the sustainable supply of energy is the only way which must be passed, an important guarantee for social development in the future. The existing conditions of the National Olympic Sports Center carry out intelligent planning and design of the micro grid, in order to promote the rational use of photovoltaic power generation technology and application of energy storage technology and automation technology based on communication and information system, enhance the Olympic Green, efficient, high quality power supply level. According to the National Olympic Sports Center planning and design of smart micro grid, conducts the research from the following four A: the overall scheme of smart micro grid planning and design, design of photovoltaic power generation system, energy storage system design, micro grid distribution Design of electric automation system. The network structure design, design of photovoltaic power generation, energy storage design, intelligent design points of design of 4 sub professional, after selection of grid structure scheme, the double shot (opening and closing) the power supply scheme. At the same time, the whole grid structure are described the design of each part, the completion of the overall planning and design scheme of smart micro grid. Then, through the comparative analysis of three different PV configuration, select suitable for the best program design, distributed photovoltaic setting, local access scheme. In Yingdong natatorium as an example, give full consideration to the needs of outdoor electric vehicle charging with the design of photovoltaic power generation system, electric vehicle charging, including photovoltaic power generation system structure, the main technical characteristics and general electric vehicle charging electric circuit design, the photovoltaic power generation is discussed. The prediction problem of power system, thus completing the design of the photovoltaic power generation system. Secondly, analyzes the characteristics of various energy storage devices, through comparative analysis, ultimately determine the concentration of the liquid flow battery storage as a smart micro grid scheme, and completed the overall design of the energy storage system. Finally, the main function of the micro grid energy management system design and system structure were described in detail, the distribution system is divided into three levels: system structure of master station layer, sub station layer, the terminal layer, and gives the main functions of each layer, to achieve the overall design of the distribution automation system diagram. This paper design case to show modern information new material technology, energy storage technology and the great changes of new power grid structure to the power grid, automatic control and adaptive optimization of all aspects of the Olympic Sports Center, the park will be a safer network All, reliable, clean, efficient and economical smart microgrid, which brings good demonstration effect, plays a leading role in the popularization of micro grid, the popularization of green energy, energy saving and emission reduction.
