Method of power disturbing signals denoising based on relaxation iteration
基于松弛迭代的电能扰动信号的去噪方法*

This paper propounded a method of the power disturbing signals denoising based on relaxation iteration, and it used the time domain structure relations between the partial catastrophe points and their neighborhood points within the set window to judge whether the sampling points of the signals are catastrophe points, and then disposed differently.The mulation experiments prove that disposing the power disturbing signals with relaxation iteration algorithm is able to obtain the higher signal noise ratio and preserve more catastrophe information than five points mean algorithm and five points median algorithm.
