摘　　要：随着电力系统的快速发展,其对安全性标准提出了更严苛的要求。变电站是电力传输的关键节点,其中电气设备的绝缘稳定性直接关系着电网的安全运行。局部放电是一种绝缘体内部缺陷区域因场强超限引发的细微放电现象,不仅是绝缘体性能退化的直接体现,也是推动其进一步恶化的重要因素。通过算法对变电站电气设备进行局部放电检测与精准定位,可以提前识别并消除绝缘隐患,增强供电的稳定性,降低事故风险与经济损失。文中剖析了局部放电现象的具体机制,探讨了局部放电检测与实时定位技术算法。With the rapid development of the power system,it puts forward more stringent requirements for safety standards.Substations are key nodes of power transmission,in which the insulation stability of electrical equipment is directly related to the safe operation of the power grid.Partial discharge is a subtle discharge phenomenon caused by the overrun of field strength in the defective area of the insulator.It is not only a direct manifestation of the degradation of insulator performance,but also an important factor that promotes its further deterioration.Partial discharge detection and precise positioning of electrical equipment in substations through algorithms can identify and eliminate hidden insulation hazards in advance,enhance the stability of power supply,and reduce accident risks and economic losses.In this paper,the partial discharge mechanism is analyzed,and the algorithm of partial discharge detection and real-time positioning technology is discussed.
