Описание: These elements allow greatly improved levels of performance in Si monolithic low-noise amplifiers, power amplifiers, up-conversion and down-conversion mixers and local oscillators. Accurate knowledge of inductance values, quality factor (Q) and the influence of ad- cent elements (on-chip proximity effects) and substrate losses is essential.

Описание: This thesis addresses a novel application of network modelling methodologies to power transformers. It develops a novel thermal model and compares its performance against that of a commercial computational fluid dynamics (CFD) code, as well as in experiments conducted in a dedicated setup built exclusively for this purpose. Hence, the thesis cross-links three of the most important aspects in high-quality research: model development, simulation and experimental validation.Network modelling is used to develop a tool to simulate the thermal performance of power transformers, widely acknowledged to be critical assets in electrical networks. After the strong de-regulation of electricity markets and de-carbonization of worldwide economies, electrical networks have been changing fast. Both asset owners and equipment manufacturers are being driven to develop increasingly accurate modelling capabilities in order to optimize either their operation or their design. Temperature is a critical parameter in every electric machine and power transformers are no exception. As such, the thesis is relevant for a wide range of stakeholders, from utilities to power transformer manufacturers, as well as researchers interested in the energy industry. It is written in straightforward language and employs a highly pedagogic approach, making it also suitable for non-experts.
Описание: Being one of the most expensive and important elements, a power transformer is a highly essential element, whose failures and damage may cause the outage of a power system. In practice, transformer condition assessment is mainly conducted by experts or trained on-site engineers based on a number of diagnostic techniques. In recent years, computational intelligence techniques have been widely utilized for advancing power transformer condition assessment methods. This book presents a number of novel intelligent techniques and approaches to deal with power transformer winding distortion and deformation assessment problem based on frequency response analysis and incipient faults classification problem in oil-filled power transformers based on dissolved gas analysis. Both theoretical introduction to the subject and practical examples using experimental measurements and simulation results are given. This book will benefit anyone associated with power transformer modelling and conditional assessment. It will also be useful for those working on applying computational intelligence to solving parameter identification and decision making problems in technical systems.

Описание: This is a comprehensive examination of the principles and implementation of CMOS active inductors and transformers, and a review of emerging applications in high-speed analog signal processing and data communications over wire and wireless channels.
This book is an all-in-one resource on the development and application of variable frequency transformers to power systems and smart grids. It introduces the main technical issues of variable frequency transformers (VFT) systematically, including its basic construction, theory equations, and simulation models. Readers will then gain an in-depth discussion of its control system, operation performance, low frequency power oscillation, and technical economics, before proceeding to practical implementation and future developments. The related concepts of energy revolution, third generation grids, and power system interconnection are discussed as well.
The first, comprehensive introduction to variable frequency transformers (VFT)
An in-depth look at the construction of VFT, with simulations and applications
Demonstrates how to assess the control system and overall system performance
Analyses future developments, energy revolution and power system interconnections
Variable Frequency Transformers for Large Scale Power Systems is a timely overview of the state of the art for VFT as it is increasingly adopted in smart grids. It is intended for engineers and researchers specializing in power system planning and operation, as well as advanced students and industry professionals of power engineering.
Описание: The necessity and importance of the standardization of electrical apparatus was recognized in Germany as early as 1894 and . the first rules ("Sicherheitsvorschriften f r elektrische Starkstromanlagen gegen Feuersgefahr") came into force in that country in 189S. In the U. S. of America the first discussion on Standardization of Generators, Motors and Transformers took place in 1898 which resulted in the appointment of a Committee and the subsequent acceptance of the rules proposed by it. In England the BritishEngineeringStandards Association was formed in IgOI. In connection with the British Standards an explanatory note appears necessary: The B. E. S. A. 's rules have for many years been the only generally accepted Standards. Since 19I3 the British Electrical and Ailied Manufacturers Association, representing the most important powerful British manufacturing firms, have issued Standardization Rules of their own which have attained considerable commercial importance, A special edition of these rules has been issued for export work which on the whole are guided by ideas similar to those embodied in the B. E. S. A. rules. As far as can be gleaned from the article in the th "Electrical Review" (Vol. 86 Nr. 2, 216, April 16 1920) it isintended to publish a new revision of the B. E. S. A. 's rules which will probably contain some of the recommendations of the B. E. A. M. A., so that this will probably mean the return to one single system of Standards for Britain.
