摘要
小波变换以其优良的时频分析特性在电力系统故障诊断及信号分析方面获得了广泛的应用,而基于单片机的故障检测装置不能适应小波算法的高要求。采用ARM微处理器进行设计,提出了一种基于小波变换的直流系统接地故障检测装置的实现方案,构建了一个完整的软、硬件平台。实验结果表明,新装置的ARM微处理器可以实现小波算法,满足了检测方案的要求。
Wavelet transform,which has excellent time-frequency analysis features,is applied widely in the power system fault detection and signal analysis.Fault detection devices based on the single-chip cannot meet the high demands of the wavelet algorithm.In this paper,ARM microprocessor is used in DC system grounding fault detection device to build a complete soft and hardware platform.The experimental results show that the new device can meet the requirements of the wavelet algorithm detection.
