摘　　要：当今社会电力污染日益加剧,人们对暂态电能质量扰动的关注越来越多。针对社会电力污染问题基于LabVIEW的虚拟仪器平台模拟出暂态电能质量的4种扰动信号,如电压骤升,电压骤降,电压波动及暂态振荡等,对电能质量的研究提供扰动信号源。同时,基于LabVIEW虚拟仪器平台对暂态电能质量信号波形进行了实时储存功能,导出扰动信号波形图,对监测电能质量具有良好的实际使用价值。经过LabVIEW平台进行相关实验,模拟出扰动暂态电能质量的4种信号,结果表明通过该设计可以对电能质量进行监测。Nowadays, power pollution is becoming more and more serious. More and more attention is paid to transient power quality disturbance. In this paper, four kinds of disturbance signals of transient power quality, such as voltage surge, voltage sag, voltage fluctuation and transient oscillation, are simulated based on the virtual instrument platform of LabVIEW for social power pollution problems. The disturbance signal source is provided for the study of power quality. At the same time, based on LabVIEW virtual instrument platform, the transient power quality signal waveform is stored in real time, and the disturbance signal waveform is derived, which has a good practical value for the monitoring of power quality. Through relevant experiments on LabVIEW platform, four kinds of signals disturbing transient power quality are simulated. The results show that the design can be used to detect power quality.
