摘要

本文对传统的半周离散傅立叶变换(HCDFT)算法进行了改进。主要目标是将半周期数据窗口的速度与有效的衰减直流分量消除方法相结合。将该算法与其他半周期算法进行了比较，结果表明该算法瞬态响应平稳，超调量最小。

Half-Cycle DFT-Based Phasor Estimation Algorithm for Numerical Digital Relaying

In this article, a modification of the traditional half-cycle discrete Fourier transform (HCDFT) algorithm is proposed. The main objective is to combine the speed of a half-cycle data window with an efficient decaying DC component elimination method. The proposed algorithm was compared to other half-cycle ones, revealing the smoothest transient response and lowest overshoot.
