Abstract

A new design of power quality monitoring device (PQMD) based on dual-CPU is proposed in this paper. These two CPU are all Digital Signal Processor (DSP), and one is responsible for data computing (DC-DSP), another one is responsible for peripheral control (PC-DSP). These two DSP can exchange data by dual-port RAM, and a variety of power quality data processing and analysis can be achieved by this PQMD. This design takes full advantage of the high-speed and powerful data processing capability of DSP. Combining IQmath library, the DC-DSP can quickly realize a variety of power quality analysis capabilities, and the PC-DSP can achieve a variety of peripheral module control through the CPLD and provide rich means of communication to meet different application demands. Testing and field trials show that the device is stabled, reliable and accurate.
