在电能质量信号检测中,去噪和保留突变点的信息是两个非常重要的问题.为此在给出对偶顺序形态变换的定义,同时在最小平均绝对误差(MAE)准则下,实现对顺序形态滤波的百分位值的自适应处理的基础上,提出了一种基于自适应顺序形态滤波方法.据此不仅能抑制扰动信号中的噪声,而且可以保留突变点的信息.对比仿真结果证实了滤波算法的有效性.

Adaptive order morphology filter was proposed for two crucial issues in power quality detection, which are the de-noising and keeping the break points' information of the power quality signal. The dualistic order mor-phology transformation was proposed in this paper firstly, then the adaptive processing of the percentile in order mor-phological filtering was implemented under a minimizing criterion of the mean absolute error (MAE). The filter can not only de-noise, but keep the break points' information. The simulation results indicate that the method is effec-tive.
