摘　　要：通过LabVIEW图形编程模拟和测量在正弦电力波形中不同谐波、噪声和脉冲瞬态的研究。其测量分析结果可以显示在仪器上,如电脑屏幕上的前面板,我们把它叫做虚拟仪器。通过虚拟仪器仪表,工程师和科学家可以减少开发时间,设计高质量的产品,降低设计成本,主要关注其波形。这有助于有效使用电力和改善电力系统的可靠性。By knowing the exact amount of harmonics,transient impulses and noise distortion in the system,it is possible to take appropriate actions to reduce their harmful effects.graphical programming of LabVIEW has been utilized to simulate and measure different harmonics,noise and impulsive transients in the sinusoidal voltage waveforms.Results have been displayed on instrument like front panels on a computer screen,called virtual instruments.With virtual instrumentation,engineers and scientists can reduce development time,design higher quality products,lower their design costs,and keep close watch on waveforms.This helps in efficient use of electric power,and system reliability is also improved at the same time.
