A NOVEL FAULT DIAGNOSIS APPROACH OF SMART TRANSMISSION GRID BASED ON KNOWLEDGE GRID TECHNOLOGY
Ziguan Zhou, Xiang Sean Zhou · 2013
There are some problems in current power grid fault diagnosis system based on expert system such as timeconsuming diagnosing and difficulty in on-line expert knowledge maintenance especially in high level dispatching centre. A novel fault diagnosis approach of smart transmission grid based on knowledge grid technology was presented in this paper for solving problems mentioned above. Firstly, the knowledge grid technology was introduced to smart transmission grid fault diagnosis field. Then the knowledge map of fault diagnosis was designed according to the background of practical power system application. And the generation methods of each part in the knowledge map were analyzed in detail. Finally, a distinction between fault diagnosis system of power grid based on expert system and knowledge grid technology was contrasted with a power grid practical applications test, and the applicable conditions of two methods were described too.
