摘　　要：随着现代电力系统管理、控制、性能要求的不断提高,使得电能质量监控成为供用电企业的普遍做法。通过了解电力系统中准确谐波次数、瞬态脉冲和噪声畸变,可采取适当的措施,降低其有害的影响。LabVIEW图形编程被用来模拟和测量在正弦电力波形中不同谐波、噪声和脉冲瞬态,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,这有助力于有效电力使用和改善电力系统的可靠性。The increased requirements on supervision,control,and performance in modern power systems make power quality monitoring a common practice for utilities.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.In the present study,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.
