| Abstract: | Seen shortcoming of the traditional monitoring systems of power quality,this article advances a new monitoring method of power quality,the method is based on TMS320F2812. The system processing the synchromous sampled signals uses fast Fourier transform.Thereby the system can analyse and display the five targets of the power quality.The results of the experiment show that the speed of TMS320F2812 processing data can satisfy the requirement of the online monitoring.The system can reflect the changes of each power quality target quikely and accurately.Therefore,the system can well adapted to the power quality monitoring requirements. |
