【摘要】：配电网自动化为实现配电网智能化提供了非常重要的技术支持,不仅有效改善了配网生产、运行以及调度的管理水平,也为供电企业带来了良好的经济收益和社会效益,为电力用户提供更为优质的电能质量和电力服务。经过十几年的农网改造,我国农村平均电力基础设施水平大幅提升,极大地促进了农村消费升级。在主网架和供电能力得到切实加强和保障的前提下,响应新一轮农网改造升级的号召,如何有效推进农村电网配电系统自动化实施进程,进一步打造安全可靠的电力环境,实现人性化的电力服务以及高效益的运行状态在促进农网改造升级方面有着十分关键的研究意义。本文经过分析农村电网配电自动化系统实施所需满足的技术要求,从配电系统总体架构入手,深入研究了农村配电自动化系统建设过程中包括主站、监测终端以及通信体系在内的主要构成部分应遵循的建设原则。针对农村电网工作环境复杂多样、负荷分布稀疏等实际情况,分别对监测终端设计和通信体系建设提出了更高的要求。本文提出了农村电网配电自动化系统监测终端的设计目标、应用功能,并应用分层结构和模块化设计思想,分别给出了监测终端软硬件设计方案,为提高配电自动化系统的整体可靠性提供了有力保障。本文探讨了农村配用电通信网络的相关内容,分析比较了目前几种较为主流的通信方式分别在结构和运行特性上的优缺点,并提出采取光纤和无线多网络紧耦合的组网方式,在遵循以光纤为主,无线为辅这一通信组网原则的前提下,更好地组建安全可靠、易于管理的通信网络。最后,给出了芜湖县配电系统自动化工程实现方案,进一步阐述落实农村电网配电系统自动化对用电安全性、可靠性、经济性等方面带来的巨大效益。总而言之,有关农村电网配电系统自动化的研究不仅对供用电部门有紧迫的实际意义,对农网配电系统自动化项目的落实也有着较为突出的指导作用,而且对推进服务新型城镇化和美丽乡村建设这一战略目标是至关重要的。
[Abstract]:Distribution network automation provides very important technical support for the realization of intelligent distribution network. It not only effectively improves the management level of distribution network production, operation and dispatch, but also brings good economic and social benefits to power supply enterprises. To provide higher quality power quality and power services for power users. After more than ten years' transformation of rural power network, the level of rural average power infrastructure has been greatly improved, which has greatly promoted rural consumption upgrading. On the premise of strengthening and guaranteeing the main grid and power supply ability, in response to the call of the new round of rural power network transformation and upgrading, how to effectively promote the implementation process of rural power distribution system automation, and further create a safe and reliable electric power environment, The realization of humanized electric power service and the high benefit operation state have very important research significance in promoting the transformation and upgrading of the rural power network. Based on the analysis of the technical requirements for the implementation of the distribution automation system in rural power grid, this paper begins with the overall structure of the distribution system, and deeply studies the construction process of the distribution automation system in rural areas, including the main station. Monitoring terminal and communication system should be followed by the main components of the construction principles. In view of the complex and diverse working environment and sparse load distribution in rural power grid, higher requirements are put forward for the design of monitoring terminals and the construction of communication system. In this paper, the design goal and application function of the monitoring terminal of distribution automation system in rural power network are put forward, and the hardware and software design scheme of the monitoring terminal is given by using the hierarchical structure and modular design idea, respectively. It provides a strong guarantee for improving the overall reliability of distribution automation system. This paper discusses the related contents of rural power distribution communication network, analyzes and compares the advantages and disadvantages of several popular communication modes in structure and operation characteristics, and proposes a tight coupling network mode of optical fiber and wireless multi-network. Based on the principle of optical fiber and wireless, a secure and easy to manage communication network is established. Finally, the realization scheme of power distribution automation project in Wuhu County is given, and the great benefits brought by the implementation of distribution system automation in rural power grid on the safety, reliability and economy of power consumption are further expounded. In a word, the research on the automation of distribution system in rural power grid is not only of urgent practical significance to the power supply department, but also has a more prominent guiding role in the implementation of the automation project of the distribution system of rural power network. Moreover, it is very important to promote the strategic goal of serving new urbanization and beautiful rural construction.
