摘要
Abstract
To develop a more efficient and more precise method for simultaneously measuring phasor, frequency and amplitude, the main measurement algorithm of synchronous phasor is analyzed, and the existing measurement method is introduced. The recursive Fourier algorithm, whose calculation quantity is less, is introduced to the traditional DFT algorithm to form an improved discrete Fourier algorithm. A kind of frequency measurement method is proposed. The error of synchronous phasor measurement is analyzed, and improvement schemes are also raised. Experiment demonstrates the correctness of the proposed synchronous phasor measurement algorithm based on recursive DFT.关键词
