基于EMD-ICA的风电机组信号盲分离研究

Research on Blind Separation of Wind Turbine Signals Based on EMD-ICA

为了去除风力机机组的噪声与振动信号等强干扰信号,采用EMD和ICA技术进行强信号盲分离。盲处理的优点是可以分离未知传递过程和源信号数量的混合信号。为了验证此算法的分离效果与可行性,给出了仿真实验。

To eliminate noises and vibration signal in wind turbine unit, this paper uses EMD and ICA technology to perform strong signal blind separation. The advantage of blind processing is that it can separate the mixed signal of the unknown transfer process and the number of source signals. In order to verify the separation effect and feasibility of this algorithm, a simulation experiment is given.
