【摘要】：随着我国电力工业不断发展,电力系统自动化进入了崭新的发展阶段。然而电力需求与电网设施不协调的局面仍然突出,特别是配网建设相对落后的情况尤为突出。为改变配网建设落后的现象,国家把农网改造投资作为重要的投入方向。以此来改善配网的运行可靠性,减少故障停电时间,为经济发展提供可靠的电力保障。配网自动化建设是农网改造的重点内容,目前,配网自动化系统的配置和实施原则更加强调监测功能。在此背景下,如果能通过整合配网领域目前所应用的各类信息系统资源,充分利用营配信息集成系统现有数据,对营配信息集成系统中的配网线路拓扑结构、开关设备属性、分支线路的实时电流和配变电流负荷等信息进行采集、分析、整合和过滤,开发一款研发周期短,成本费用低的智能辅助监控软件,实现对配网线路运行状态的准实时监控及智能告警功能,强化对各分支线路的管理,对解决配网盲调的问题等具有重要的现实意义。本文以计量自动化系统的实时负荷数据为基础,以营配信息集成系统业务工单为依据,研究在配网自动化没上线或终端监测硬件设备覆盖率不高的条件下配网线路(尤其是分支线路)故障停电的远程监测及故障定位的辅助诊断方法,并且利用主配网拓扑拼接、GIS网络拓扑追踪算法及单线图动态渲染技术,充分利用营配信息集成系统现有主配网拓扑拼接、计划停电和有序用电业务数据,集成主网SCADA10KV线路故障跳闸和计量自动化电流负荷、配变失压等实时监测数据,研究并建设配网线路远程监测及故障诊断辅助功能,实现配电网线路故障停电的实时报文、语音告警和可视化展示,为解决长期困扰供电企业配网故障发现晚、故障定位慢的问题提供新的思路。
[Abstract]:With the continuous development of China's power industry, power system automation has entered a new stage of development. However, the situation of disharmony between power demand and power network facilities is still prominent. In order to change the backward situation of distribution network construction, the government regards the investment of rural power network transformation as an important input direction to improve the reliability of distribution network operation and reduce the time of power failure. The construction of distribution network automation is the key content of rural power network transformation. At present, the configuration and implementation principle of distribution network automation system emphasizes the monitoring function more. If we can integrate all kinds of information system resources used in the field of distribution network, make full use of the existing data of camp and distribution information integration system, and make use of the topology structure of distribution network and the attribute of switch equipment in the distribution information integration system, Collecting, analyzing, integrating and filtering the information of real time current and distribution current load of branch line, we develop an intelligent assistant monitoring software with short R & D cycle and low cost. To realize the function of quasi-real-time monitoring and intelligent alarm to the running state of distribution network, and to strengthen the management of each branch line, This paper is based on the real-time load data of the metrological automation system and on the basis of the business worksheets of the distribution information integration system. This paper studies the remote monitoring of distribution line (especially branch line) failure and the auxiliary diagnosis method of fault location under the condition that the distribution network automation does not go on line or the terminal monitoring hardware equipment coverage is not high. And using the main distribution network topology splicing GIS network topology tracing algorithm and single line graph dynamic rendering technology, making full use of the existing main distribution network topology splicing, planning power outage and orderly power consumption business data, the existing main distribution network topology splicing, the planned outage and the orderly power consumption business data are fully utilized in the camp distribution information integration system. By integrating the real-time monitoring data of SCADA10KV line fault tripping and automatic current load measurement, distribution transformer voltage loss and other real-time monitoring data, the auxiliary functions of remote monitoring and fault diagnosis of distribution network line are studied and constructed to realize the real-time message of distribution network line fault outage. Voice alarm and visual display provide a new way of thinking for solving the problem of late fault discovery and slow fault location in power supply enterprises for a long time.
