The Research and Design of Power Quality Monitoring System Based on ARM and DSP

Power quality problems have seriously affected power system stability and normal operation of national economy. The traditional method of power quality monitoring has an obvious limitation. Now the importance of power quality becomes more prominent, this paper presents a monitoring system based on ARM and DSP, in which the main processor is ARM and DSP is a co-processor. It makes a full use of ARM embedded control system and powerful DSP data-processor capacity, so that the power quality monitoring can meet the requirements of real-time. Moreover, it will be able to achieve the remote monitoring of power quality through the embedded Web Server. At last, Qtopia Core is used as the human-machine interface, which realizes the sampling indicator of chinesization effect.
