Abstract:A new design of ARM and DSP electrical network monitoring device is proposed in this paper. TMS320F2812 DSP and high precision ADS8364 are used for power quality data synchronous acquisition. Nuttall window are studied, the using of the phase of rotation adjustment and multilayer summation reduce the spectral interferences, the proposed can achieve the electrical harmonic analysis and fulfill the electric parameter measuring requirements. Distributed electric Monitoring values are computed in the DSP, which communicates with S3C2440 embedded with Linux system via serial port and transfers power data and computed values. By logging in to the homepage of the observation system, power grid manager can check the operation status of electric power network in real-time and deal with the failure messages, user can view the consumer information and power grid parameters in real-time. The operation system fulfill the electric parameter measuring requirements of distributed electric energy supply system and it is satisfactory in remote network monitor control and real-time.
