The Application of Mathematical Morphology in the Disturbance Detection of Power Quality

文章在前人研究的基础上,提出基于αβ变换以及dq变换相结合的电能质量扰动检测方法。该方法根据电压扰动信号的特点,借助数学形态学方法选择合适结构元素设计2级滤波器,进行电压扰动信号的检测定位,最后仿真算例证明了该方法计算简单,能够快速、准确地定位电压扰动信号。

A method of combining α β conversion and dq conversion to detect power quality disturbances is proposed based on previous studies,which makes use of the characteristics of voltage perturbation signal.It designs two filter elements by choosing a suitable structural element to locate the voltage perturbation signal.The simulation results show that the proposed method is simple,and they can locate the disturbances of the voltage signals quickly and accurately.
