研究了电力电缆故障信号的去噪问题。基于PSO算法对小波阈值去噪进行优化研究,同时利用优化后的算法对所采集到的故障信号进行去噪。结果表明,所提出的PSO算法能够有效去除电力电缆故障信号,且能完整保留原始故障信号的特征。

This paper focuses on the de-noising of power cable fault signals,proposes to optimize the wavelet threshold de-noising based on PSO algorithm,and uses the optimized algorithm to de-noise the collected fault signals.The simulation results show that the PSO algorithm proposed in this paper can effectively remove the power cable fault signal,and can completely retain the characteristics of the original fault signal.
