【摘要】 随着配电网建设速度的加快,配电网的自动化成为提高配电网供电质量的必然要求。同时随着配电网自动化水平的不断提升,使得越来越多的监控设备投入使用。这些监控设备数量巨大,必须借助相应的监控系统才能有效地采集数据、处理信息。因此配电网自动化监控系统的建设是不可或缺的一项重要工作。本文分析了配电网自动化建设的背景,说明了本课题的实际意义;分析了国内外配电网自动化的发展现状。一般情况下,配电网按电压等级划分成高压、中压、低压配电网3个等级;本文说明了配电网的结构及其特点;阐述了配电网自动化的概念和配电网自动化的内容。分析了现行配电网自动化监控系统的基本结构,并对其总体功能需求和主站层软件需求进行分析,提出总体设计方案;根据模块化设计的原则,提出监控系统的功能模块分类设计。对监控系统的智能终端的硬件设计进行了分析,主要包括了核心电路、电源模块、时钟模块、存储模块和电量采样模块、开关量输入输出模块等;提出了智能终端的软件设计以及具体功能设计。在主站层功能需求的基础上,提出了主站组态软件的总体设计,以及主站与智能终端之间的通信、数据库管理等。最后,本文给出实际的设计成果。通过配电网自动化监控系统的设计,对配电网自动化的管理要求和功能需求有了一个全面的把握;通过功能设计、硬件选型搭配、软件编程调试,在硬件、软件上基本实现了监控系统的全部功能。该监控系统在配电网自动化的应用,使得供电公司的配电网自动化水平用了大大的提高。得益于该监控系统的可靠运行,供电企业进一步提高了配电网的运行、维护、管理等方面的工作效率,有效地缩短了故障排查、处理时间,进一步改善了配电网运行状况,进一步提高了电能质量,取得良好的经济效益和社会效益。更多还原

【Abstract】 As the construction of distribution network has been speeding up, automation of distribution network has become an inevitable requirement to improve the quality of distribution network power supply. The continuous improvement of the level of distribution network automation makes more and more monitoring equipment put into use. The number of monitoring equipment is huge, it is necessary to use the corresponding monitoring system to effectively collect data and process information. So the construction of distribution network automation monitoring system is an indispensable important work.This paper analyzes the background of the distribution network automation construction, illustrates the practical significance of the subject, and analyzes the development status of domestic and foreign distribution network automation. Under normal circumstances, the distribution network according to the voltage level is divided into of high, middle and low voltage distribution network three grades; this paper shows the structure and the feature of the distribution network, expounds the contents of distribution automation and the concept of distribution network automation. The basic structure of the existing distribution network automation monitoring system are analyzed, and on the overall functional requirements and main station layer software requirements analysis, the paper puts forward the overall plan of design; according to the principle of modular design, the monitoring system of classification of the functional modules. The monitoring system of intelligent terminal presents the hardware design, including the core circuit, power module, clock module, a storage module and a power sampling module, switch input and output module; the software design of the intelligent terminal and the specific function design is proposed. Based on the functional requirements of the main station, the overall design of the main station configuration software is proposed, and the communication between the master station and the intelligent terminal, database management and so on. Finally, the actual design results are given.Through the design of the monitoring system in distribution automation system, for the distribution network automation management requirements and functional requirements with a comprehensive grasp; through the function design, selection of hardware collocation, software programming and debugging, in hardware, software, the basic realization of the all the functions of the monitoring system. The successful development and operation of the monitoring system greatly improves the automation level of distribution network of the power supply enterprise. Thanks to the reliable operation of the monitoring system, power supply enterprises to further improve the distribution network operation, maintenance, management and other aspects of the work efficiency, effectively shortens the troubleshooting, processing time, to further improve the status of the distribution network operation, further improve the electrical energy quality, achieve good economic and social benefits.更多还原
