摘要
当前的输电线路导线风偏在线监测节点布设形式多为单向,监测的覆盖范围较小,导致异常监测响应耗时延长,为此设计超高压输电线路导线风偏在线监测方法并对应用效果进行验证分析。根据当前的在线监测需求及标准,先进行初始监测指标设置及模态分析,采用多维交叉的方式,扩大监测的覆盖范围,布设多维交叉在线监测节点,以此为基础构建输电线路导线风偏FBG在线监测模型,采用相位测定实现在线监测处理。测试结果表明:对比于传统的称重法导线风偏在线监测小组、传统Φ-OTDR导线风偏在线监测小组,设计的超高压线路导线风偏在线监测小组最终得出的异常监测响应耗时被较好地控制在0.2 s以下,说明在当前的监测范围之内,监测的质量和效率得到了明显地提升,监测效果更佳,具有实际的应用价值。
Current online monitoring methods for wind-induced wire swing mostly adopts unidirectional layout of monitoring nodes,and thus are confounded by small monitoring coverage and sluggish response to anomalies.In view of this the present work studied modification of method to online monitor wind-induced wire swing deviation of ultra-high voltage transmission lines.By considering current online monitoring requirements and standards,initial monitoring indicators were set up and modal analysis was carried out.A multi-dimensional crossover method was adopted to expand the coverage of monitoring and rationally arrange multi-dimensional crossover nodes.Based on this,a transmission line wind-induced swing FBG online monitoring model was constructed which uses phase measurement to realize online monitoring processing.The final test results indicated that compared to conventional technologies such as weighing-based method,andΦ-OTDR method,the proposed method can achieve responding time consumption to anomalies effectively controlled below 0.2 s,indicating an obvious improved quality and efficiency within the current monitoring range.
