摘要
随着一些长距离、大容量输电系统相继建成投运,近年在江苏阳淮系统、南方电网等发生过很多次磁暴侵扰事件,因此磁暴导致的地磁感应电流(GIC)对我国大规模电网的影响是值得关注的问题,通过对电网GIC的在线监测,掌握GIC水平对电网运行安全非常重要。论文在已开发的电网GIC监测装置基础上,提出利用SQL SEVER数据库、DELPHI开发后台软件并组成监测网络系统;成果包括开发了后台软件的人机界面认证模块、数据采集与通讯、分析处理、数据显示、查询分析模块等,形成了一个完整的后台管理软件;后台软件的运行、调试结果表明,软件的功能模块和整体性能达到了预期的设计要求。
With a little long distance , high-capacity transmission system consecutively established, the magnetic storm invaded events had happened very many times in the late years in Jiangsu Yangcheng-Huaiyin and south power system, therefore the geomagnetic induced current (GIC) that the magnetic storm leads to affects the problem being to be worth paying close attention to large-scale power grid of our country , it is very important by monitoring GIC online , grasping the GIC level to operation safety of power grid. The thesis is based on development power grid GIC monitoring device , which suggests the exploitation of the backstage software and the composition of monitors network system using the data base SQL SEVER and DELPHI program; Achievement includes the software man-machine interface attestation module , the data collection and communication , analysis , data display , inquiring data module , which have formed one entirely manage background; The software operation , debugging result have indicated background software module and overall function have reached expected design demand.
