【摘要】：2015年,国家电网公司正式提出构建全球能源互联网、推动能源绿色发展‖战略计划。全球能源互联网是以特高压电网为主干网架(通道),以传输清洁能源为主导、全球互联泛在的坚强智能电网。根据以上内容可知,构建全球能源互联网就是要建设坚强的、智能的、自动化的电网网架,那么智能、坚强、自动化的电网建设就必须位于首位。通信技术作为实现电网智能化、互动化和大电网运行控制的重要部分,必须顺应智能化电网的发展,就需要将通信的安全性作为重点领域进行创新和突破。首先,论文阐述了配电自动化系统的网架结构,以及配电自动化在实时性、易扩容、可靠性等方面对通信网的要求。根据这几个方面的要求对EPON技术运用于配电通信网系统进行了业务需求分析及预测、抗单/多点失效能力等九个方面的可行性分析,针对EPON技术的三种最常见组网模式进行优缺点方面的分析和比较,分析计算了三种组网模式的网络有效性及可靠性,最后对3种组网模式的成本以图表的形式进行了比较。最后结合金昌地区配网自动化建设现状和通信网络建设现状,而且可以满足配网自动化系统对通信业务需求的基础上,对通信网进行了分析,依据建设原则与目标,确定了金昌地区配电通信网的建设方案,并确定采用手拉手模式进行组网。手拉手保护的组网模式可以使金昌地区的配电通信网建设成果获得收益与成本最佳比例的成效,达到最优的性价比。因此,在金昌地区配电通信网的接入层采用EPON的手拉手组网模式进行组网。本文结尾对配电通信网未来的发展方向进行了展望。
[Abstract]:In 2015, State Grid Corporation formally proposed to build a global energy Internet to promote the green development of energy strategic plan. The global energy Internet is a strong smart grid with UHV grid as its backbone (channel, dominated by transmission of clean energy) and global interconnection. According to the above content, the construction of global energy Internet is to build a strong, intelligent, automated grid network, then intelligent, strong, automated grid construction must be in the first place. As an important part of intelligent, interactive and large power grid operation control, communication technology must adapt to the development of intelligent power grid, so it is necessary to innovate and break through the security of communication as a key area. Firstly, the paper describes the network structure of distribution automation system and the requirements of distribution automation in real-time, easy to expand, reliability and other aspects of the communication network. According to the requirements of these aspects, the feasibility of EPON technology applied to distribution communication network system is analyzed in nine aspects, such as service requirement analysis and forecast, anti-single / multi-point failure ability, etc. This paper analyzes and compares the advantages and disadvantages of the three most common networking modes of EPON technology, analyzes and calculates the network validity and reliability of the three networking modes, and finally compares the cost of the three networking modes in the form of charts. Finally, based on the present situation of distribution automation construction and communication network construction in Jinchang area, and on the basis of satisfying the communication business requirements of distribution automation system, the paper analyzes the communication network, and according to the construction principles and objectives, The construction scheme of the distribution communication network in Jinchang area is determined, and the hand-held mode is adopted to set up the network. The construction of distribution communication network in Jinchang area can get the best ratio of profit and cost and achieve the best performance-price ratio. Therefore, the access layer of the distribution communication network in Jinchang area adopts the EPON mode of hand-in-hand networking. At the end of this paper, the future development of distribution communication network is prospected.
