【摘要】 变电设备的智能运检离不开先进的设备状态感知技术。随着电力系统智能化发展，对于变电站电气设备状态感知传感器的需求逐年上升。变电站中的稳态电磁骚扰和瞬态电磁骚扰对状态感知传感器，特别是微功耗智能传感器的寿命造成巨大威胁，从而导致在线监测数据错误率高，误报警频发。文章通过统计分析变电站现场实际的低频电磁骚扰特性参数和高频电磁骚扰特性参数，为现场电气设备状态感知传感器应开展的电磁兼容试验要求提供理论支撑。更多还原

【Abstract】 The intelligent operation and inspection of substation equipment cannot be separated from advanced equipment state sensing technology. With the intelligent development of power system,the demand for state sensing sensors of electrical equipment in substation has been increasing year by year. The steady state electromagnetic disturbance and transient electromagnetic disturbance in substation pose a great threat to the life of state sensing sensors,especially to the life of micro-power smart sensors,which lead to high error rate of online monitoring data and frequent false alarms. In this peper the statistical analysis of the actual steady-state and transient electromagnetic disturbance characteristics of substation provides theoretical support for the electromagnetic compatibility test requirements of the field electrical equipment state sensing sensors.更多还原
