摘要
电力光缆通信在电力自动化中起到了关键作用,由于技术和管理上的原因,电力光缆网络由于人为因素导致的破坏时有发生,严重威胁电网的安全运行。随着电力光缆网络大规模应用,迫切需要一种主动发现的电力光纤防外破监测系统。文章基于传统分布式光缆监测系统设计思路和电力光缆运维数据分析,结合实际工程,在1 台设备上采用2 块Φ-OTDR 传感模块对光缆线路粗放式轮询和精确定位的双模块设计思路,对光缆的运行状态进行分布式在线监测,对外破及时预警及精确定位。介绍了防外破监测系统设计,并结合实验数据,论证方法的可行性。
Communication of power optical cable plays a key role in power automation. Due to technical and management reasons, the destruction of power optical cable network caused by human factors occurs from time to time, which has seriously threatened the safe operation of power grid. With the large-scale application of power optical cable network, there is an urgent need for an active discovery of power optical cable monitoring system against external damage. This paper based on the design idea of traditional distributed optical cable monitoring system and the analysis of power optical cable operation and maintenance data, combined with the actual engineering, adopts the design idea of dual-OTDR sensor module using two Φ-OTDR sensing modules in a device, carries out distributed on-line monitoring of the operation status of the cable, and early warning of external damage. Then, the software implementation method is mainly introduced. At last, combining with the experimental data, the feasibility of the method is demonstrated.
