【Abstract】 By analyzing the situations of the electric energy monitoring equipments home and abroad, aiming at the demand of power department and the practical applications. A new surveillance device based on DSP(Digital Signal Processing) thchnology is developed. The application of DSP in the electric power systems is introduced first in this paper. The author briefly analyzes some problems caused by using single chip microprocessor as front porch control, and proposes the hardware and software structure which uses industrial level micro-controller AM1 88ES as master CPU, TMS320F206 as slave CPU, and can perform measurement, control and communication. A high-speed and high-precision distributed data acquisition and processing system is designed based on DSP. The synchronous data sampling of the supervising system is realized by multi-channel collection retaining and A/D transformation circuit. Data between the master and slave boards can be transferred by dual-port RAM. According to the special characters of the electric power system, the algorithm implementation of digital signal processor is presented.The equipment can provide comprehensive and accurate recording data for quality study of electric energy. Besides, it displays real time curve and frequency spectrum.更多还原
