摘　　要：传统电能质量检测装置大多采用DSP技术,开发周期长,功能单一。基于LabVIEW虚拟仪器开发平台,开发一种新型的电能质量分析软件,可利用FFT、STFT、WT、HHT等多种现代信号处理方法对电能质量信号进行分析,并利用状态机结构实现人机交互。检测结果表明,软件既能分析电能质量的稳态指标,又能检测电能质量的暂态扰动,操作简单,多种功能,界面友好,具有广泛的使用前景。DSP technology is used in most of traditional power quality detection devices, with long development cycle and limited functions. Based on LabVIEW virtual instrument development platform, a new type of power quality analysis software is developed. Transformation-based methods such as FFT, STFT and HHT are adopted to analyze power quality signals, using state machine architecture to achieve human-computer interaction. The test results show that the software can not only analyze the steady-state indexes of power quality, but also detect the transient disturbance signal. There are some advantages such as simple operations, friendly interface, multi-functions and so on, which make the software have an extensive application prospect.
