The main objective of this paper is to perform transient stability analysis using the electrical power systems design and analysis software namely ETAP. The purpose of performing transient stability on the power system is to study the stability of a system under various disturbances. The stability of the power system is the ability of generators to remain in synchronisation even when subjected ...

Many operations in power grids, such as fault detection and event location estimation, depend on precise timing information. In this paper, a novel time stamp attack (TSA) is proposed to attack the timing information in smart grid. Since many applications in smart grid utilize synchronous measurements and most of the measurement devices are equipped with global positioning system (GPS) for prec...

This master’s thesis presents a proven-correct implementation of a distributed topology construction algorithm based upon the Thallner topology construction method for creating a minimal ∆-node connected fault-tolerant overlay graph. The algorithm works in asynchronous fault-tolerant distributed systems augmented with failure detectors. A detailed proof shows that given a perfect propose module...

The paper is engaged with the framework of designing adaptive fault estimation for linear continuous-time systems with distributed time delay. The Lyapunov-Krasovskii functional principle is enforced by imposing the integral partitioning method and a new equivalent delaydependent design condition for observer-based assessment of faults are established in terms of linear matrix inequalities. Asy...

The paper proposes a control system with the brake and the steering for developing a driver assistance system. The purpose is to design a cruise control method to track the road geometry with a predefined velocity and guarantee the road stability of the vehicle simultaneously. An actuator selection method is developed in the control design, in which the actuator limits, energy requirements and ...

Non-fragile fault-tolerant controller is designed for a class of linear uncertain time-delayed systems. Two cases of controller perturbation are investigated in view of different application conditions. One case is the controller gain attenuation, the other is random uncertainty caused by noise possibly existing in an industrial field. The controller to be designed can guarantee systems to have...

This paper presents the robust fuzzy fault tolerant control (FFTC) for nonlinear wind energy conversion systems (WECS) in the presence of bounded sensor faults and the state variable unavailable for measurement based on Takagi-Sugeno (TS) fuzzy model. Sufficient conditions are derived for robust stabilization in the sense of Lyapunov asymptotic stability and are formulated in the format of line...

This paper deals with dynamic output feedback control of continuous-time active fault tolerant control systems with Markovian parameters (AFTCSMP) and state-dependent noise. The main contribution is to formulate conditions for multiperformance design, related to this class of stochastic hybrid systems, that take into account the problematic resulting from the fact that the controller only depen...

Protective relays are designed to quickly and correctly clear the fault and minimize the impact of disturbances on power system. Occasionally, some complex conditions may cause relays to perform unintended or incorrect operation, which may further deteriorate the system condition and even jeopardize the stability of the entire system. This paper discusses three categories of solutions for analy...

In this paper, an observer-based fault-tolerant control (FTC) method is proposed for a class of networked control systems (NCSs) with transfer delays. Markov chain is employed to characterize the transfer delays. Then, such kind of networked control systems are modelled as markovian jump systems. An observerbased FTC scheme using the delayed state information and the estimated fault value is pr...
