摘要
以往的直流系统接地故障检测装置大都是基于单片机设计的,难以实现一些先进、复杂的检测算法。针对这种情况,提出了基于LabVIEW并结合PCI采集卡设计的接地故障检测装置的设计方案,充分利用了虚拟仪器的特点,克服了单片机资源有限的缺点,实现了基于小波变换的先进检测方法,大大提高了直流系统接地故障诊断的准确性。
Majority of the grounding error detection devices in DC systems are based on single chip microprocessor（SCM）, but such device lacks the ability to carry out advanced and complicated algorithms.Based on the situation,a DC system grounding fault detection device in terms of LabVIEW and PCI DAQ Card is presented.This method is able to overcome the limitation of SCM by making full use of the virtual instrument.Furthermore,implementation of advance detecting method such as wavelet is made possible, and it effectively improves the accuracy of the error detection in a DC system.
