摘要
为区别故障信号、非故障信号,实现对电缆线路故障的准确检测,设计了基于免疫Agent的电力电缆线路故障检测系统。利用前端检测电路为故障分析模块、测距方式切换模块提供电量传输信号,完成系统前端检测装置的连接。按照免疫Agent检测原理提取电力电缆线路故障信号的特征,联合已获取信号对象,求解检测插值指标的具体数值。结合各级硬件设备结构,完成系统设计。实验结果表明,该系统可同时检测波频为10~20 Hz、40~50 Hz、60~70 Hz的故障信号与波频为20~30 Hz、30~40 Hz、50~60 Hz的非故障信号,可以在精准辨别故障与非故障信号的同时,实现对电力电缆线路故障的准确检测。
In order to distinguish fault signals from non fault signals and realize the accurate detection of cable line faults,a power cable line fault detection system based on immune agent is designed.The front⁃end detection circuit is used to provide power transmission signals for the fault analysis module and the ranging mode switching module to complete the connection of the front⁃end detection device of the system.According to the immune agent detection principle,the characteristics of power cable line fault signals are extracted,and the obtained signal objects are combined to solve the specific value of the detection interpolation index.Combined with the structure of hardware equipment at all levels,the system design is completed.The experimental results show that the system can detect the fault signals with wave frequencies of 10~20 Hz,40~50 Hz,60~70 Hz and the non fault signals with wave frequencies of 20~30 Hz,30~40 Hz,50~60 Hz at the same time.It can accurately identify the fault and non fault signals and realize the accurate detection of power cable line faults at the same time.
