Special Session 3
Fault Detection on High-Voltage Electrical Devices
“高压电力设备故障检测”
As voltage levels continue to rise and renewable energy sources are integrated at scale, high-voltage power equipment (e.g. transformers, gas-insulated switchgear, bushings, and power lines) operates under increasingly severe conditions. If insulation degradation and incipient defects are not detected in a timely manner, they can trigger partial discharge, overheating, or even insulation breakdown, leading to unplanned outages or cascading accidents that pose a substantive threat to grid security. Despite notable advances in sensing technologies and data processing capabilities, field detection still faces persistent bottlenecks.
This special session focuses on the core challenges and frontier methods in fault detection on high-voltage devices. Topics of interest include, but are not limited to: multi-parameter partial discharge detection and interference suppression techniques, deep learning-based discharge pattern recognition and defect localization, vibration monitoring and mechanical defect diagnosis for GIS and transformer windings, and multi-source information fusion and edge computing for online monitoring systems. The objective of this session is to offer theoretical support and technical reference for enhancing the operational reliability and maintenance intelligence of high-voltage equipment.
随着电压等级的不断提升以及可再生能源的大规模接入，高压电力设备（如变压器、气体绝缘开关设备、套管和电力线）的运行条件愈发严苛。若绝缘劣化及初期缺陷未能及时发现，可能引发局部放电、过热甚至绝缘击穿，从而导致计划外停运或连锁事故，对电网安全构成重大威胁。尽管传感技术和数据处理能力已取得显著进步，但现场检测仍面临持续的瓶颈问题。
本次特别会议聚焦于高压设备故障检测中的核心挑战和前沿方法。感兴趣的议题包括但不限于：多参数局部放电检测和干扰抑制技术、基于深度学习的放电模式识别和缺陷定位、气体绝缘开关设备和变压器绕组的振动监测和机械缺陷诊断，以及在线监测系统的多源信息融合和边缘计算。本次专题旨在为提高高压设备的运行可靠性和维护智能化提供理论支持和技术参考。
