智能电网输电线路在线监测技术

On-line Monitoring Technology for Smart Grid Transmission Lines

输电线路在线监测技术是一门具有交叉学科性质的新兴技术,是进行状态监测、巡视检查、大修的前提和基础。电网前期管理人员采用定期巡线和定期检修的方式,有效地保证了输电线路的安全运行.但存在着运行效率低下和维护费用过高的问题.更因为缺乏实时监测手段,不能实时反映线路的状态变化而造成的事故。在不影响设备运行的情况下,可通过在线监测提取各种状态信息,由监控中心专家软件判断设备运行状态,并及时提供预警警报信息,把各种意外消灭在萌芽状态。

Transmission line on-line monitoring technology is a new interdisciplinary technology,is the condition monitoring,patrol inspection,overhaul of the premise and foundation.However,there are some problems,such as low efficiency and high maintenance cost,and the accident is caused by the lack of real-time monitoring means,which can not reflect the change of line state.In recent years,with the rapid development of computer,under the condition of not affecting the operation of equipment,all kinds of state information is extracted by on-line monitoring,and the expert software of monitoring center judges the running state of equipment and provides early warning information in time.Nip accidents in the bud.
