摘　　要：电力系统扰动信号检测装置的研制是检测和改善电能质量的首要问题。以Hilbert-Huang变换为核心算法,开发了一套电能质量检测系统。该系统硬件平台主要由信号调理与数据采集电路组成,实现信号采集功能。软件部分由Matlab的GUIDE开发,实现数据存储、HHT分析、波形显示等功能。系统包含PSCAD/EMTDC仿真模型检测模式与实测数据检测模式,分别对仿真模型的电能质量数据与电气化铁道实测数据进行检测,结果表明,该系统既能准确检测暂态扰动信号,又能有效分析谐波成分。The development of power system disturbance signal detection device is the most important issue to detect and improve the power quality. Based on Hilbert-Huang Transform, a power quality detection system is developed. The hardware consists of signal conditioning circuit and data acquisition circuit, and realizes signal acquisition. The software is developed by Matlab＇s GUIDE. It realizes data storage, HHT analysis and waveform display. The system contains two detections modes, namely the PSCAD/EMTDC simulation model detection mode and the measured data detection mode. The power quality data collected from the simulation model and data measured from the electrified railway are detected respectively. The results show that the system can detect the transient disturbance signal accurately, and analyze the harmonic components effectively.
