一种多源海量局部放电信号脉冲的并行提取方法

Parallel Method for Extracting Pulses from Multi-source Massive Partial Discharge Signals

针对多源、海量局部放电(Partial Discharge,PD)信号的放电脉冲提取问题,提出了一种基于消息传递接口(Message Passing Interface,MPI)的并行化方法。该方法采用管理者-工人-写者模式,由管理者动态分配任务,工人负责业务计算并由写者回收计算结果,将数据管理和任务执行分离。此外,由管理者辨别信号来源并发送给工人作为数据文件解析和算法参数设置的依据,能够解决多源异构信号处理问题。实验结果表明所提方法高效可行,且具有良好的加速比,脉冲提取准确率达90%以上,满足工程应用需求。
