摘要
为了有效监测局部放电信号,利用FPGA的高速并行处理能力,设计一种基于FPGA的特高频局部放电监测硬件实现系统。文中介绍了系统的硬件设计及FPGA实现原理。系统使用提升小波变换对采集数据进行脉冲提取,然后对有效脉冲进行特征提取,最后将提取的特征参数送入PC端,使用DBSCAN将脉冲的特征提取结果进行聚类分离。实验结果表明,基于高速FPGA设计的局部放电监测硬件系统能将不同脉冲信号有效分离。
In order to effectively monitor the partial discharge(PD)signal,a hardware implementation system of ultra high frequency(UHF)partial discharge monitoring based on FPGA was designed by using the high-speed parallel processing capability of FPGA.The principle of the hardware design and FPGA implementation of the system were introduced.The system used lifting wavelet transform to extract pulses from the sampled data.Then the feature of the effective pulse was extracted.Finally,the extracted feature parameters were sent to the PC.DBSCAN was used to cluster the feature extraction results of the pulses.The experimental results show that the partial discharge monitoring hardware system based on high speed FPGA can effectively separate different pulse signals.
