Abstract :
A new monitoring method of power quality based on the industrial computer is proposed. Using fast Fourier transform, synchronous sampling signal from the data acquisition card is processed. This system can analyze and display the power quality parameters. The results of the experiment show that the system can monitors and analyzes the power quality parameters in power systems with long time, and harmonic numbers can be analyzed to 100 and phase error is very small, and can monitoring a number of points at the same time. The system can reflect the changes of each power quality quickly and accurately, so the system can well adapted to the power quality monitoring requirements.
