【摘要】：随着人类社会经济和技术的不断发展,电力在人的生产和生活中的作用日益突出,可靠、安全、高效的是电力客户对供电部门的基本需求。为了实现这一目标,电力部门在配电网的调度自动化、电量集抄、负荷控制、配变监测、电能质量(电压)监测等方面进行了了大规模的信息化和自动化改造,使得供电水平也得到了大幅提升。但是由于各个系统独立运行和使用归属不同的业务部门,不同系统由于设计目标和运行要求的不同,导致系统之间数据无法互联互通,出现信息孤岛,且系统之间接口实现复杂,存在数据存储冗余,形成大量的人、财、物的浪费。按照对配电网信息统一采集、统一存储和统一利用的原则,搭建一个基于实时数据库的中低压配电网统一数据采集与监控系统,是未来配电网信息采集处理的必然方向。本文以眉县供电分公司上王变124上公线作为试点,通过添加联络开关、完善线路监测控制单元,配置对应的通信设备,搭建了配电网数据统一采集系统实施的硬件环境,对供电企业所需要、所感兴趣的所有配电网数据进行统一处理、规范存储、有效整合,建立实时及准实时的数据仓库,作为各个电力业务管理系统基础数据唯一权威、可靠的来源,通过集成式交互总线作为接口,为各项业务内容提供标准的数据来源和信息支撑,满足供电企业对电网监控、生产管理、营销管理等对数据准确性、完整性、一致性和安全性的要求。试点线路包含了配电网中的各种终端的数据采集,验证了多种通信方式,采集数据库和其他应用系统顺利对接,说明统一数据采集在配电网的应用是可行的,更是必要的。同时,统一数据采集在县级配电网应用对于建设智能配电台区具有重要的意义,能够为智能配电台区的监控和管理提供有力的数据支撑。
[Abstract]:With the development of human economy and technology, the role of electric power in human production and life is increasingly prominent, reliable, safe and efficient is the basic needs of power supply departments. In order to achieve this goal, the power department has carried on the large-scale informationization and the automation transformation in the distribution network dispatch automation, the electricity quantity collection copy, the load control, the distribution transformer monitoring, the power quality (voltage) monitoring and so on. The level of power supply has also been greatly improved. However, because each system operates independently and belongs to different business departments, different systems have different design objectives and operation requirements, which lead to the data being unable to be interconnected and interlinked between the systems, resulting in isolated information islands. And the interface between the system is complex, there are data storage redundancy, forming a large number of people, money, material waste. According to the principle of unified collection, storage and utilization of distribution network information, it is an inevitable direction to build a unified data acquisition and monitoring system based on real-time database for distribution network information collection and processing in the future. This paper takes Shangwang transformer 124 common-line of Meimei Power supply Branch as a pilot project, through adding contact switch, perfecting line monitoring and controlling unit, configuring corresponding communication equipment, and setting up the hardware environment for the implementation of unified data acquisition system of distribution network. All the distribution network data needed and interested by the power supply enterprises should be unified, standardized storage, effectively integrated, real-time and quasi-real-time data warehouse established, as the sole authority of the basic data of each electric power business management system, The reliable source, through the integrated interactive bus as the interface, provides the standard data source and the information support for each service content, satisfies the power supply enterprise to monitor to the grid, the production management, the marketing management and so on to the data accuracy, the integrity, Consistency and security requirements. The pilot line includes the data acquisition of various terminals in the distribution network and verifies various communication modes. The data collection database and other application systems are successfully docked, which shows that the application of unified data acquisition in the distribution network is feasible and necessary. At the same time, the application of unified data acquisition in the county distribution network is of great significance for the construction of intelligent distribution station area, which can provide powerful data support for the monitoring and management of intelligent distribution station area.
