Synchronous Generators and Excitation Systems Operating in a Power System
In simulation tests of dynamic states of the power system (PS), the database of parameters of mathematical models of generating units is most commonly used. In many cases, the parameter values are burdened with large errors. Consequently, the results obtained are not reliable and do not allow drawing true conclusions. This monograph presents the developed methods and tools supporting the process of measurement determination of reliable values of parameters of mathematical models of synchronous generators and excitation systems. Special measurement tests are the basis for determining the parameters. The tests can be carried out in conditions of normal operation of generating units, in which electrical machines operate in the state of saturation of magnetic cores, and voltage regulators can reach limits. This book is intended for specialists in power engineering as well as students of faculties of electrical engineering interested in issues of PS transient states.
Homeownership, Renting and Society
On the eve of the financial crisis, the USA was inhabited by almost 70 percent homeowning households, in comparison to about 45 percent in Germany. Homeownership, Renting and Society presents new evidence showing that this homeownership gap already existed between American and German cities around 1900. Existing explanations based on culture, government housing policy or typical socio-economic factors have difficulties in accounting for these long-term cross-country differences. Using historical case studies on Germany and the USA, the book identifies three institutional domains on the supply-side of the housing market – urban land, housing finance and construction – that set countries o...
Dwell
At Dwell, we're staging a minor revolution. We think that it's possible to live in a house or apartment by a bold modern architect, to own furniture and products that are exceptionally well designed, and still be a regular human being. We think that good design is an integral part of real life. And that real life has been conspicuous by its absence in most design and architecture magazines.
Electromagnetic Modeling by Finite Element Methods
Unlike any other source in the field, this valuable reference clearly examines key aspects of the finite element method (FEM) for electromagnetic analysis of low-frequency electrical devices. The authors examine phenomena such as nonlinearity, mechanical force, electrical circuit coupling, vibration, heat, and movement for applications in the elect
Handbook of Large Turbo-Generator Operation and Maintenance
The comprehensive guide for large turbo-generator operation and maintenance The Handbook of Large Turbo-Generator Operation and Maintenance is an expanded 3rd edition of the authors’ second edition of the same book. This updated revision covers additional topics on generators and provides more depth on existing topics. It is the ultimate resource for operators and inspectors of large utility and industrial generating facilities who deal with multiple units of disparate size, origin, and vintage. The book is also an excellent learning tool for students, consulting and design engineers. It offers the complete scope of information regarding operation and maintenance of all types of turbine-dr...
