摘　　要：电力系统发生故障后,将在电网中产生大量的暂态噪声,危害电气设备的正常工作,破环电力系统的稳定性。由于消除暂态噪声是电力系统继电保护中极其重要的环节,故本文介绍全波及半波傅里叶算法在消除暂态噪声中的应用,并进行仿真分析。提出改进算法应用于消除故障时特有的暂态噪声,并对其性能进行仿真分析,验证改进算法的有效性。Transient noises are caused by power system fault in the grid, which have large sum of harm on working of electrical equipment normally, it leads to work unsteadily for the power system. Considering it is extremely important part to eliminate transient noises in power system relay protection, thus, in this paper full-wave Fourier algorithm and half-wave Fourier algorithm are introduced to eliminate transient noises in the application of the power system, and simulations are carried out respectively. Two improved algorithms are proposed to eliminate proper transient noises in power system relay protection, and simulations with their performances are analyzed to verify the validity.
