摘要

The instantaneous parameters, amplitude, phase and frequency of power system signals provide valuable information about the status of the power system, particularly when these parameters can be obtained simultaneously from locations that are remotely located from each other. Phasor Measurement Units (PMU's) placed at these remote locations can perform these simultaneous time synchronized measurements. In this work digital signal processing techniques and Field Programmable Gate Array (FPGA) technology was used for the real-time estimation of power system signal parameters. These parameters were estimated based upon an approach utilizing the Hilbert transform and formation of an analytic signal as a basis for the estimation of instantaneous phase, frequency and amplitude of power system signals. However, the emphasis in this work is upon the accurate estimation of instantaneous phase and frequency because of the level of complexity to accurately achieve this practically. Three different methods for frequency estimation were implemented and compared, based upon the criterion of accurate frequency measurement, to assess the efficacy of the three techniques. The MATLAB/SIMULINK simulation environment together with Xilinx System Generator, a high level digital signal processing development tool for FPGA's, was used to practically implement the estimation techniques.
