| Abstract: | In this paper, the characteristics, requirement and some practical problems of fault line detection in medium voltage power network are analyzed. And some main grounding fault line detection are compared and researched. Based on all above methods, a composite intelligent approach for fault line detection is brought forward. Namely, information combined technology is used for distribution operation status and zero current, harmonic current, transient current are detected online with modern computer technology, then composite comparison and analysis is conducted. If necessary, harmonic current will be increased to enhance the tested signal and improve the accuracy of fault detection. |
