An expert system for power systems fault analysis
IEEE Transactions on Power Systems, 1994This paper describes an expert system for fault analysis which has been put into field tests in the dispatch centre of the North East China Electric Network. Previous expert systems for fault analysis on transmission power systems are mainly based on information about the operation of protective relays, whereas this new expert system mainly uses ...

Fuzzy fault query approach in the fault diagnosis of a power plant system
Proceedings 1999 IEEE/RSJ International Conference on Intelligent Robots and Systems. Human and Environment Friendly Robots with High Intelligence and Emotional Quotients (Cat. No.99CH36289), 2003Based on the theory of fuzzy recognition, this method only depends on experience and statistical data to set up the fuzzy fault query relationship between the outside phenomena (fault characters) and the fault sources (fault states), so that it reaches the goal of quick diagnosis.

Instantaneous Faults Detection in Power System
2018 Twentieth International Middle East Power Systems Conference (MEPCON), 2018Power quality covers a wide range of issues that affect utilities and consumers. Problems associated with power quality can be classified into different categories. Interruption, sag, swell, voltage and frequency variation. These are typical faults that could lead to a serious damage in a power network.

Computer‐aided power system fault analysis
Computer Applications in Engineering Education, 2011AbstractMost of power systems courses contain mathematical analysis, animations, simulations, and technical tours to power stations. However, experimental studies particularly in fault analysis are very difficult due to high voltages and currents passed through short circuits.

Power system fault calculations are invariably undertaken using the mathematical technique termed `symmetrical components' analysis (alternatively termed `phase-sequence components' analysis). A wealth of literature exists on this subject and therefore the purpose of this text is to provide an abbreviated, concise and relevant explanation focusing on ...

Fault calculations in power system subject to multiple faults
[1990] Proceedings. The Twenty-Second Southeastern Symposium on System Theory, 2002Techniques for considering multiple faults at different locations in a three-phase electrical power system are discussed. The faults may be completely user defined; e.g. a single phase-to-ground fault may be specified on any phase and at any combination of locations.

Fault diagnosis in fluid power systems
Engineering Simulation, 1996Algorithms for fault detection and isolation (FDI) based on the use of mathematical models are becoming a powerful addition to many fluid power control systems. Many useful methods have been proposed but the great majority of these are based on the use of linear models.
