基于频谱修正算法的电动机自适应保护装置的研究

Development of Self-adaptive Electric Rely Protection with Spectral Amendment

针对传统的傅氏算法存在不能同步采样产生测量误差的缺陷,提出频谱修正算法,并将这种算法引入保护装置中,给出了硬件电路和软件设计框架.经样机调试,各方面性能增强.

<Abstrcat>This article points out the defects in traditional DFT and raises a new type of Spectral amendment.The framework of hardware Circuit and software design is given. When it is employed in the protect device. By experimenting on the device the better result is obtained..
