Vector Control of Three-Phase AC Machines : System Development in the Practice
This monograph covers the area of vector control of three-phase AC machines, in particular induction motors with squirrel-cage rotor (IM), permanent excited synchronous motors (PMSM) and doubly-fed induction machines (DFIM), from the viewpoint of the practical design and development. Main focus is on the application of the IM and the PMSM in electrical drive systems, where the method of the field-orientated control has been successfully established in the practice, and on the use of the grid voltage orientated controlled DFIM in the wind power plants.
Transient Analysis of Electric Power Circuits Handbook
Every now and then, a good book comes along and quite rightfully makes itself a distinguished place amongthe existing books of the electric power engineering literature. This book by Professor Arieh Shenkman is one of them. Today, there are many excellent textbooks dealing with topics in power systems. Some of them are considered to be classics. However, many of them do not particularly address, nor concentrate on, topics dealing with transient analysis of electrical power systems. Many of the fundamental facts concerning the transient behavior of electric circuits were well explored by Steinmetz and other early pioneers of electrical power engineering.
Three-Phase Diode Rectifiers with Low Harmonics : Current Injection Methods
In this book, principles of the current injection are discussed first. This discussion is followed by an analysis of various magnetic current injection devices. The third harmonic current injection is discussed next, and several current injection networks are analyzed. The optimal current injection is the topic that follows, and the requirements imposed to the current injection network in order to provide the optimal current injection are derived. Several current injection networks that provide the optimal current injection are proposed, and some parasitic effects are discussed. Recovery of the power taken by the current injection networks is analyzed, and two types of passive resistance emulators are analyzed in detail, the current-loaded resistance emulator, and the voltage-loaded resistance emulator. Avoiding the inductor of the current injection network results in mutipulse operation of the current injection based rectifiers with passive resistance emulators, which is discussed next.
Interfacial Transport Phenomena
This is an extensively revised second edition of Interfacial Transport Phenomena, a unique presentation of transport phenomena or continuum mechanics focused on momentum, energy, and mass transfer at interfaces. In addition to tightening the focus of the book there are two important additions: an extended discussion of transport phenomena at common lines or three-phase lines of contact, as well as a new theory for the extension of continuum mechanics to the nanoscale region immediately adjacent to the interface. Applications and supporting experimental data are provided and discussed in detail. This book is written for the advanced student of transport phenomena. The emphasis is upon achieving an in-depth understanding based upon first principles. It is designed to prepare the reader for active research. It includes exercises and answers, and can serve as a graduate level textbook.
Electrochemistry of Immobilized Particles and Droplets
Immobilizing particles or droplets on electrodes is a novel and most powerful technique for studying the electrochemical reactions of three-phase systems. It gives access to a wealth of information, ranging from quantitative and phase analysis to thermodynamic and kinetic data of electrode processes. Three-phase electrodes with immobilized droplets provide information on the electrochemistry of redox liquids and of compounds dissolved in inert organic liquids. Such measurements allow the determination of the Gibbs energies of the transfer of cations and anions between immiscible solvents, and thus make it possible to assess the hydrophobicity of ions – a property that is of great importance for pharmaceutical applications, biological studies, and for many fields of chemistry.The monograph gives, for the first time, a comprehensive overview of the results published in more than 300 papers over the last 15 years. The experiments are explained in detail, applications from many different fields are presented, and the theoretical basis of the systems is outlined.
