摘要
随着电力系统电压等级的提升,电缆绝缘状态的可靠性成为保障电网安全运行的重要因素。局部放电是电缆绝缘老化和缺陷的关键指示信号,利用在线监测局部放电特征,可有效预测和防范绝缘故障的发生。设计并实现了一种基于局部放电的110 kV电缆绝缘在线监测系统,系统通过信号检测、特征参数提取以及故障定位诊断模型的构建,达到高效、准确的绝缘状态监测与故障诊断,提升了电缆运行的安全性和可靠性。
With the improvement of power system voltage level,the reliability of cable insulation status has become an important factor to ensure the safe operation of power grid.Partial discharge is the key indication signal of cable insulation aging and defects.Using on-line monitoring of partial discharge characteristics can effectively predict and prevent the occurrence of insulation faults.A 110 kV cable insulation on-line monitoring system based on partial discharge is designed and implemented.Through signal detection,feature parameter extraction and fault location diagnosis model construction,the system achieves efficient and accurate insulation state monitoring and fault diagnosis,and improves the safety and reliability of cable operation.
