针对于突发性故障的特点,提出了一种基于数学形态学的故障定位方法,通过选择适当的结构元素,根据腐蚀和膨胀运算的特点设置适当的组合形态运算,借鉴软阈值计算中的消噪方法,设计高效的故障定位算法,仿真实验证明了数学形态学在故障定位中所具有的优越性。
Aimed at the features of abrupt faults, a new fast processing metho& based on mathematical morphology is proposed to locate fault, by use of appropriate morphologic structure element, proper combination of erosion and dilation morphologic operators, a fast abrupt faults location method is formed, assisted by a de-noise method of the soft threshold. Simulating experiment proves the superiority of using mathematical morphology.
