基于数据分析的变压器套管新型在线监测预警策略研究

open access: yesGaoya dianqi, 2018
套管是电力变压器的重要附件,其安全稳定运行至关重要。为此,常采用在线监测技术对其运行状态进行实时监测。在电网内部,变压器套管在线监测系统已有一定应用。然而,监测数据不仅取决于套管自身绝缘性能,而且受温度、湿度和系统运行电压等环境因素影响,且当前各套管监测厂家推荐的预警策略各异,难以满足应用要求。因此研究适宜的在线监测预警策略至关重要;文中对广东电网在运变压器套管的介损值历史监测数据进行了统计分析。研究发现变压器套管在线监测应用过程中会出现短时性、间歇性的数据异常,异常率接近1%,导致监测系统告警 ...
