【摘要】：随着我国经济的快速发展,新增配变等配电线路设施数量急剧增加,馈电线路走廊资源越来越少,配网建设及运行管理面临严峻挑战。根据我国新能源政策的发展战略,未来分布式电源大规模并网是解决传统发电污染问题的必然方向。针对分布式电源并网的技术方案和标准,专家学者们已经进行了大量的研究,也取得了一定的研究成果。总结分布式电源在国内存在的并网难点问题,可归结信息通信技术上的障碍使其并网时的潮流、谐波、安全运行等方面问题产生时不能有效的动作。本文总结了分布式电源并网和智能配电网的通信需求,提出了适合各类业务的通信方式,以此为基础采用骨干层、接入层、汇聚层的三层结构建立了含分布式电源的配电通信系统和建设方案。分析了IEC61850和IEEE1547标准对分布式电源并网的相关规定,按照国网关于配电网规划的导则和技术导则提出了完整的分布式电源并网信息需求、分布式电源分类方法和面向对象的信息建模方法,建立了并网分布式电源与电网交互的信息模型。最后结合具体地区通信业务的需求和并网地区的特点,研究各通信技术与DER并网业务的匹配性,对DER并入10kV站的不同通信方式创建了共性的评价指标体系,进一步采用模糊一致的AHP评价方法,对各通信方式进行评价并给出指导建议。
[Abstract]:With the rapid development of economy in our country, the number of new distribution line facilities such as distribution transformer increases sharply, and the resources of feed line corridor are less and less. The construction of distribution network and the management of distribution network are faced with severe challenges. According to the development strategy of China's new energy policy, large-scale grid connection of distributed power sources is the inevitable direction to solve the problem of traditional generation pollution in the future. Experts and scholars have done a lot of research on the technical scheme and standard of distributed power grid connection, and have also obtained some research results. This paper summarizes the difficult problems of connecting to the grid of distributed power supply in China, which can be attributed to the obstacles in information and communication technology that make the problems of power flow, harmonics and safe operation not effective when they are connected to the grid. This paper summarizes the communication requirements of distributed power generation and smart distribution network, and puts forward a communication mode suitable for all kinds of services. Based on this, the backbone layer and access layer are adopted. The three-layer structure of the convergent layer establishes the distribution communication system with distributed power supply and the construction scheme. This paper analyzes the relevant regulations of IEC61850 and IEEE1547 on the grid connection of distributed power generation, and puts forward the complete information requirements of grid connection of distributed generation according to the national network guidelines and technical guidelines on distribution network planning. The information model of the interaction between distributed power supply and power grid is established by the classification method of distributed power generation and the object-oriented information modeling method. Finally, according to the demand of communication services in specific areas and the characteristics of grid-connected areas, this paper studies the matching between various communication technologies and the network connection services of der, and creates a common evaluation index system for different communication modes in which der is incorporated into 10kV stations. Furthermore, the fuzzy consistent AHP method is used to evaluate each communication mode and give some guidance suggestions.
