This book was released on 2019-06-18 with total page 678 pages. Available in PDF, EPUB and Kindle. Book excerpt: Uses real world case studies to present the key technologies of design and application of the synchronous generator excitation system This book systematically introduces the important technologies of design and application of the synchronous generator excitation system, including the three-phase bridge rectifier circuit, diode rectifier for separate excitation, brushless excitation system and the static self-stimulation excitation system. It fuses discussions on specific topics and basic theories, providing a detailed description of the theories essential for synchronous generators in the analysis of excitation systems. Design and Application of Modern Synchronous Generator Excitation Systems provides a cutting-edge examination of excitation system, addressing conventional hydro-turbines, pumped storage units, steam turbines, and nuclear power units. It looks at the features and performance of the excitation system of the 700MW hydro-turbine deployed at the Three Gorges Hydropower Plant spanning the Yangtze River in China, as well as the working principle and start-up procedure of the static frequency converter (SFC) of pumped storage units. It also expounds on the composition of the excitation transformer, power rectifier, de-excitation equipment, and automatic excitation regulator—in addition to the performance features of the excitation system of conventional 600/1000MW turbines and the excitation system of the 1000MW nuclear power unit. Presents cutting-edge technologies of the excitation system from a unique engineering perspective Offers broad appeal to power system engineers who require a better understanding of excitation systems Addresses hydro-turbines, pumped storage units, steam turbines, and nuclear power units Provides an interdisciplinary examination of a range of applications Written by a senior expert in the area of excitation systems Written by an author with over 50 years' experience, Design and Application of Modern Synchronous Generator Excitation Systems is an excellent text that offers an interdisciplinary exposition for professionals, researchers, and academics alike.

Book excerpt: For a one-semester senior or beginning graduate level course in power system dynamics. This text begins with the fundamental laws for basic devices and systems in a mathematical modeling context. It includes systematic derivations of standard synchronous machine models with their fundamental controls. These individual models are interconnected for system analysis and simulation. Singular perturbation is used to derive and explain reduced-order models.

This book was released on 1968 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: Controllable parameters in a power system include generator terminal voltage, generator input power and network admittances. These parameters can be controlled to damp mechanical rotor oscillation in the generators and thereby improve system transient stability. Explicit equations are derived in this thesis for the control of these parameters to introduce damping uniformly throughout a large power system. These equations are derived on the basis of minimizing a positive definite error function. Decision functions are included which inhibit damping action when it leads to system instability. This method can be used to coordinate the application of locally based damping techniques. A three-generator example is presented illustrating the damping method.

Available in PDF, EPUB and Kindle. Book excerpt: The market liberalization is expected to affect drastically the operation of power systems, which under economical pressure and increasing amount of transactions are being operated much closer to their limits than previously. These changes put the system operators faced with rather different and much more problematic scenarios than in the past. They have now to calculate available transfer capabilities and manage congestion problems in a near on line environment, while operating the transmission system under extremely stressed conditions. This requires highly reliable and efficient software aids, which today are non-existent, or not yet in use. One of the most problematic issues, very much needed but not yet en countered today, is on-line dynamic security assessment and control, enabling the power system to withstand unexpected contingencies without experienc ing voltage or transient instabilities. This monograph is devoted to a unified approach to transient stability assessment and control, called SIngle Machine Equivalent (S1ME).

This book was released on 2015 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: Attention is increasing on transient stability and secure mode of operation for power systems with asynchronous generation. This is due to asynchronous mode of generation like wind farms, increasing in capacity and displacing existing high inertia synchronous generation. Participation of wind farms, which are primarily inertia decoupled during transient disturbance, will become necessary to comprehensively analyse framework like energy function and coherency based reduction methods. This thesis investigates the impact of reduced system inertia due to asynchronous generation, on transient stability of power systems. This thesis proposes an energy function approach to assess power system transient stability impacts following increased penetration of asynchronous generation plants. The asynchronous wind farm generation is considered as an equivalent conventional synchronous generator with negligible inertia. Assessment has been carried out on single machine infinite system and three machine nine bus test system to compute critical energy and critical fault clearing time, from first principles, using potential energy boundary surface method. A new representation of plotting contours of critical clearing times on inertia space has been developed. This enables estimation of additional inertia required for a system due to inertia reduction from asynchronous generators. The results of the simulation and new graphical method confirms that transient stability margin of the system is impacted with increased penetration of asynchronous generation. This thesis also investigates coherency based analysis technique for network reduction to carry out transient stability analysis for a large power system network that has wind penetration. Identification of coherent groups targets to obtain simplified dynamic equivalent of system by aggregation of coherent generators and replacing it with an equivalent generator. The use of this equivalence can transform a large power system into a reduced model, localized into a small internal area containing the disturbance which impact stability. The New England, 39 bus 10 machine system has been used to demonstrate the methodology. Contingencies are applied with and without wind farm i.e., by replacing few synchronous generators with wind farm of similar capacity. This thesis also develops transient stability enhancement method for networks with asynchronous generation. When a machine inertia is reduced its first swing stability can be enhanced by line series compensation and also multi-swing stability using bang-bang control on series compensation. Compensation values and the lines that can participate in series compensation during contingencies are found.
