【摘要】：随着社会和经济的发展,电力行业一改过去“重发轻供”的模式,为用户提供优质的用电服务也越来越受到重视,因此,能够提升电能质量的配网自动化技术则成为目前关注的重点。在智能电网的大背景下,城市电网供电可靠性不断提升,网架结构也趋于成熟化,国网公司针对农网的配电自动化调研工作已经在部分省内开展,广大农村地区将成为开展下一阶段配网自动化建设的对象目标。本文以安徽省宿州农电公司电网作为研究对象,在结合实际情况的基础上,对所辖区域的农网自动化方案进行了设计。本文首先对宿州农电辖区所处的地理和经济现状进行了介绍,分电压等级依次列举出电网重要设备及相关指标情况,分析辖区电网和通信网络的整体情况,重点分析了辖区及试点区配电网现状,指出了实施配电自动化所存在的问题。然后对系统进行了需求分析,结合外部形势,明确配电自动化系统所需发挥的作用和系统设计目标。结合以上设计了宿州农电公司了配电网自动化整体方案,详细阐述了主站架构、功能和性能、FA以及终端设备的设计方案。最后,根据所设计配电自动化整体结构以及实现的功能,提出了主站软硬件配置,又从网架结构优化、线路改造、配电设备改造三方面详细阐述了电网所对应的一次改造方案,并对配电自动化整体投资从主站及相关系统、网架和一次设备、终端配置、通信网络建设等方面展开估算,从社会、经济、管理三方面进行了细致的效益分析。本文提出了适合宿州农电的配电自动化设计方案,为公司的配网自动化实施提供了一定的指导依据,为其他农网配电自动化建设也可起到一定参考和借鉴作用。
[Abstract]:With the development of society and economy, more and more attention has been paid to the power industry to provide high quality electricity service to customers. Distribution automation technology, which can improve power quality, has become the focus of attention. Under the background of smart grid, the power supply reliability of urban power network is continuously improved, and the grid structure tends to mature. The research work of distribution automation for agricultural power network has already been carried out in some provinces. The vast rural areas will become the target of the next stage of distribution automation construction. This paper takes Suzhou Agricultural Power Company of Anhui Province as the research object, and based on the actual situation, designs the automation scheme of the agricultural power network in the area under its jurisdiction. This paper first introduces the geographical and economic situation of Suzhou agricultural power district, lists the important equipment and related indicators of the power network by voltage level, and analyzes the overall situation of the power network and communication network in the district. The present situation of distribution network in district and pilot area is analyzed, and the problems existing in the implementation of distribution automation are pointed out. Then the system needs analysis, combined with the external situation, to clarify the role of distribution automation system and system design goals. Combined with the above, the whole scheme of distribution network automation of Suzhou Agricultural Power Company is designed, and the design scheme of main station architecture, function and performance FA and terminal equipment is described in detail. Finally, according to the overall structure and functions of the designed distribution automation, the hardware and software configuration of the main station is put forward, and the corresponding primary transformation scheme of the power network is described in detail from three aspects: the optimization of the grid structure, the line transformation and the transformation of the distribution equipment. The whole investment of distribution automation is estimated from the main station and related system, network frame and primary equipment, terminal configuration, communication network construction and so on. The detailed benefit analysis is carried out from three aspects of society, economy and management. This paper puts forward a design scheme of distribution automation suitable for Suzhou Agricultural Power Plant, which provides a certain guiding basis for the implementation of distribution automation in the company, and can also play a certain reference and reference role in the construction of distribution automation of other rural power networks.
