摘要
针对现有的电能质量检测装置的不足,以LabVIEW为平台开发了一套电能质量综合检测系统,可以对稳态和暂态电能质量进行检测。暂态电能质量检测模块利用递归复小波变换来确定暂态扰动的发生时刻,并用以基频为中心频率的单尺度小波变换能量分布曲线来进行扰动分类。基于服务器/客户端的工作模式,满足了用户对区域电网实时同步检测的要求。
To overcome some disadvantages of the current power quality monitoring devices, a comprehensive power quality monitoring system based on LabVIEW is suggested. This system is used to perform the detection of transient and steady power quality problem. The improved recursive wavelet transform is used to detect the beginning point o f the transient disturbance. The wavelet transform energy distribution curve is applied to classify the transient power qualities The c/s mode meets the requirements of consumer for monitoring local network.
