摘要:
该文提出一种基于改进集合经验模态分解(MEEMD)的复合电能质量扰动检测方法，该方法不仅能抑制分解过程中的模态混叠，而且可以减少计算量，降低重构误差。采用 MEEMD方法分解复合电能质量扰动信号，得到固有模态函数(IMF)分量，然后进行希尔伯特(Hilbert)变换，获得频率和幅值等信息，进而确定电能质量扰动信号的瞬时特征信息。MATLAB仿真结果表明，该文所提出的方法对复合电能质量扰动具有良好的分解效果，同时能够抑制模态混叠。
Abstract:
In this paper, a method for compound power quality disturbance detection based on modified EEMD(MEEMD) is proposed, this method can not only suppress the mode mixing in the decomposition process, but also reduce the calculations and reconstruction errors.The MEEMD is used to decompose the compound power quality disturbance signal to obtain the intrinsic mode function(IMF) components.Then the Hilbert transformation is performed to obtain the frequency and amplitude information and so on,thereby determining the instantaneous characteristic information of the power quality disturbance signal.The MATLAB simulation show that the method proposed in this paper has a good decomposition effect on the compound power quality disturbance and can suppress mode mixing.
