【摘要】：智能电网是现代科技、先进理念与传统电网的完美统一，对解决能源、生态、气候等全球性问题具有重要作用，是实现经济社会可持续发展的必由之路，配网自动化作为智能电网的重要组成部分，具有非常重要的作用。配网自动化系统的建设必然带来配网管理水平的提高，同时带来灵活的需求侧管理和用户驱动的增值服务市场，也为将来电力系统的调度、运行、维护、管理以及经济的发展打下坚实的基础。配网自动化在提高用户供电的可靠性，提高供电质量，，降低线损，提高供电部门劳动生产率，提高能效等方面具有良好的经济效益和社会效益。本文首先介绍了配电自动化所包括内容以及国、内外配电自动化的发展过程和现状，其次详细介绍了典型配电网自动化的模式和实现馈线自动化的技术方案，结合任丘市配电网中网架结构、电源分布、设备工作年限等实际因素分析了配电网自动化系统建设存在的问题并给出了改造方案，阐明了实施配电网自动化建设的重要性。接着详细分析了配电自动化系统中馈线自动化、通信系统及主站系统的设计方案并较全面的介绍了各部分的作用。在此基础上，结合任丘市配电网的结构特点与实际情况，确定所采用的配电自动化系统模式，馈线自动化方案、通信方案以及SCADA功能，并且介绍了配电网自动化所实现的故障检测、故障定位、故障隔离、故障恢复等功能。该配电自动化系统方案的实施，可以提高该市的供电质量和可靠性，提高了电力系统的经济效益、社会效益和技术效益。
[Abstract]:The smart grid is the perfect unity of modern science and technology, the advanced idea and the traditional power grid, it plays an important role in solving the global problems such as energy, ecology and climate. It is the only way to realize the sustainable development of the economy and society. The distribution automation, as an important part of the smart grid, has a very important role. The construction of the distribution network automation system is very important. It will inevitably bring about the improvement of distribution network management level, and bring flexible demand side management and user driven value-added service market. It also lays a solid foundation for future power system scheduling, operation, maintenance, management and economic development. Distribution automation improves the reliability of power supply, improves power supply quality and reduces line loss. The high power supply department has good economic and social benefits in terms of labor productivity and energy efficiency.
This paper first introduces the contents of distribution automation and the development process and present situation of the automation of domestic and foreign distribution. Secondly, the model of typical distribution network automation and the technical scheme to realize feeder automation are introduced in detail, and the actual factors such as network frame structure, power distribution and working life of equipment in Renqiu distribution network are analyzed. The problems existing in the construction of power grid automation system and the reform scheme are given. The importance of the construction of distribution automation is clarified. Then the design of feeder automation, communication system and main station system in the distribution automation system is analyzed in detail, and the functions of each part are introduced in a more comprehensive way. On this basis, it is combined with the Renqiu city. The structure characteristics and actual situation of the power grid, determine the distribution automation system mode, feeder automation scheme, communication scheme and SCADA function, and introduce the functions of fault detection, fault location, fault isolation, fault recovery and so on. The implementation of the distribution automation system scheme can improve the city. The quality and reliability of the power supply have improved the economic, social and technological benefits of the power system.
