Fault detection and diagnosis in nonlinear dynamical systems
Kılıç, Erdal; Leblebicioğlu, Mehmet Kemal; Department of Electrical and Electronics Engineering (2005)
The aim of this study is to solve Fault Detection and Diagnosis (FDD) problems occurring in nonlinear dynamical systems by using model and knowledge-based FDD methods and to give a priority and a degree about faults. For this purpose, three model-based FDD approaches, called FDD by utilizing principal component analysis (PCA), system identification based FDD and inverse model based FDD are introduced. Performances of these approaches are tested on different nonlinear dynamical systems starting from simple t...

Fault detection and service restoration in medium voltage distribution system
Altın, Müfit; Özay, Nevzat; Department of Electrical and Electronics Engineering (2009)
This thesis proposes an algorithm and develops a program for fault detection and system restoration in medium voltage distribution systems. In Turkey, TUBITAK-UZAY developed distribution automation system including fault detection and service restoration functions for Bogazici Electricity Distribution Company. By the time, expanding of distribution system with nonstandardized infrastructure (for example more than one circuit breaker in the feeder, mesh and closed loop feeder structure), developed automation...
Fault-tolerant control of discrete-event systems with lower-bound specifications
Moor, Thomas; Schmidt, Klaus Verner (2015-06-01)
Fault-tolerant control addresses the control of dynamical systems such that they remain functional after the occurrence of a fault. To allow the controller to compensate for a fault, the system must exhibit certain redundancies. Alternatively, one may relax performance requirements for the closedloop behaviour after the occurrence of a fault. To achieve fault tolerance for a hierarchical control architecture, a combination of both options appears to be advisable: on each individual level of the hierarchy, t...
Fault detection and data validation in refinery power production
Kahya, Tuba; Kıncal, Serkan; Department of Chemical Engineering (2014)
In refinery utility generation, boilers, steam and gas turbines are the primary equipment, producing steam as well as electricity. In boilers, high pressure steam is produced by combustion of a mixture of waste gases from the production line and natural gas – called fuel gas. The steam is at relatively high pressures and is then reduced to lower pressures in steam turbines. The resulting medium and low pressure steam are sent to the refinery for use in processes. In a gas turbine, electricity is produced by...
