Book excerpt: This paper implements Fault Current Limiting (FCL) requirements and proposed a calculation method to determine the required dc reactor value, for the purpose of the converter continuous operation during dc faults. On this basis, the Bridge- Type Fault Current Limiter (BFCL) using static non-linear controller was proposed for using in the dc grid, due to merits including minor negative influence on dc grid traditional operation, fast response to dc faults and efficient coordination with the DC Circuit Breaker (DCCB). The parameter style principle of the bridge-type FCL for dc grid was conjointly mentioned. Then the scaled-down dc experiment take a look at circuit was designed to verify the rule and performance of the bridge-type FCL. The simulation and experimental results are presented to clarify the theory and feasibility of the proposed FCL at different points of IEEE 30-bus power system, which manifest simple structure of the circuit and show feasibility of the proposed FCL.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation proposes the bridge type fault current limiter (BFCL) as well as parallel resonance type fault current limiter (PRFCL) to enhance the transient stability of multi-machine power system. Fuzzy logic controller as well as neural network predictive controller is proposed for controlling the operation of BFCL. Further, a nonlinear static controller is proposed for controlling the operation of PRFCL. An optimal reclosing technique of circuit breakers is adopted. In order to see the effectiveness of the proposed fault current limiters, their performance is compared wit that of other auxiliary devices. Moreover, the effects of cyber-attack on the performance of BFCL controllers to improve the power system stability are investigated. Genetic algorithm (GA) is applied to optimally tune the controller parameters. Simulations are performed by using the Matlab/Simulink software in different test power systems. Simulation results of both balanced and unbalanced permanent and temporary faults at different points of the test systems indicate that the proposed fault current limiters can enhance the transient stability of the power system well compared to the other auxiliary devices. Moreover, the performance of the PRFCL is better than that of the BFCL. Further, the neural network predictive controller performs better than the fuzzy logic controller for BFCL. It is noteworthy that cyber-attacks have profound effect on the controller performance and the system becomes fully unstable even with the presence of the proposed controllers of the fault current limiters.

This book was released on 2020-10-31 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book focuses on the transient modelling, stability analysis and control of power electronic systems, since these systems face severe safe operation problems the during transient period. It discusses both theoretical analysis and practical applications, highlighting the transient characteristics of converters with different control strategies, and proposes transient modelling and model reduction methods. Furthermore, it classifies the transient stability problems of the system to help the readers gain an understanding of the basic theoretical methods for analysing the power electronic system, at the same time providing sufficient detail to enable engineers to design such systems. Comprehensively describing theoretical analyses, ranging from system modelling and stability analysis to transient control, the book is a valuable resource for researchers, engineers and graduate students in fields of transient modelling, stability analysis and control of power electronic systems.

Download or read book Power System Transient Stability Improvement by FACTS Devices written by Sedaghati Reza and published by LAP Lambert Academic Publishing. This book was released on 2015-10-06 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Power System is an extremely non-linear and dynamic system, with operating parameters continuously varying. Stability is hence, a function of the initial operating condition and the nature of the disturbance. The system must be in a position to be able to adjust to the changing conditions and operate satisfactorily. The system must also withstand large disturbances, which may even cause structural changes due to isolation of some faulted elements. The significance of power system stability is increasingly becoming one of the most limiting factors for system performance. Power system transient stability is related to the ability to maintain synchronism when subjected to a severe disturbance, such as a short circuit on the bus. This book proposes a new structure of coordination between two FACTS devices for transient stability improvement of a power system. Furthermore, to achieve a quickly respond and adapt to the power system model, a neural network as a model to control the power transfer of FACTS devices are used. The significant performance of intelligent controller compared with Linear Quadratic Regulator (LQR) controller through simulation studies on an test power system.
