Applying of FFT Algorithmic in Power Substation Microcomputer Monitoring System Based on DSP2407

Abstract:

In the detection substation microcomputer AC sampling system , monitor the three-phase voltagethree-phase current , power factor ,power online in real-time. This paper describes a FFT designing idea of the synchronous sampling in AC sampling from the substation monitoring system parameters .It provided sampling and calculation methods to apply DSP, MCU measurement of AC signal , details of the mathematical model of AC electrical parameters digital sampling, the introduction of schematic diagram of hardware processing sampling signal of FFT, comparison of the realization of the software and MATLAB simulation, thus obtained the correctness of this algorithm.
