摘要
为及时发现供配电系统中压开关设备的温度变化情况,避免发生高温故障,该文提出供配电系统中压开关设备温升在线监测方法。开关设备温度数据采集模块将温度监测节点采集的温度信息传送至在线监测模块,在线监测模块通过DS证据理论融合采集的温度信息,并通过多重对抗网络模型,判断开关设备是否发生温升现象,感知其温度状态;应用自联想核算法结合感知结果,进行预警发生温升的开关设备,通过上位机呈现红外监测画面。测试结果表明,该方法能够在温差为±0.6℃的范围内,完成开关设备的温度信息采集,具备良好的温度感知性能;当健康度指标发生明显下降趋势时,及时发送预警信息,呈现红外监测画面,具备良好的温度劣化监测效果。
In order to find the temperature change of medium voltage switchgear in power supply and distribution system in time and avoid high temperature fault,an on-line temperature rise monitoring method of medium voltage switchgear in power supply and distribution system is proposed.The switchgear temperature data acquisition module transmits the temperature information collected by the temperature monitoring node to the on-line monitoring module.The on-line monitoring module fuses the collected temperature information through DS evidence theory and judges whether the switchgear has temperature rise and senses its temperature state through multiple confrontation network model;Using the Auto Association accounting method combined with the sensing results,the early warning is implemented for the switchgear with temperature rise,and the infrared monitoring picture is presented through the host computer.The test results show that this method can complete the temperature information collection of switchgear in the range of temperature difference of±0.6℃,and has good temperature sensing performance;When the health index has an obvious downward trend,send early warning information in time and present infrared monitoring picture,which has a good temperature degradation monitoring effect.
