Book Description
Surveying the technologies used to satisfy the world's demand for open, efficient, and clean electricity, Variable Speed Generators provides an in-depth examination of variable-speed generators for both stand-alone and grid-connected applications. Part of The Electric Generators Handbook, Two-Volume Set, this work offers authoritative, tightly focused treatment of the topologies, steady state and transients modeling, performance, control, design, and testing of stand-alone and grid-connected generators operating at variable speeds. Variable Speed Generators thoroughly covers all types of variable-speed generators currently in progress in distributed generation and renewable energy applications around the world. It delves into the steady state, transients, control, and design of claw-pole rotor synchronous, induction, permanent magnet-assisted synchronous, and switched reluctance starter alternators for hybrid-electric vehicles. It also discusses PM synchronous, transverse-flux PM, and flux-reversal PM generators for low-speed wind and hydro energy conversion as well as linear-motion alternators for residential and spacecraft applications. Numerous design and control examples illustrate the discussion. The promise of renewable, sustainable energy rests on our ability to design innovative power systems that are able to harness energy from a variety of sources. Variable Speed Generators supplies the tools necessary to design, validate, and deploy the right power generation technologies to fulfill tomorrow's complex energy needs.

Book Description
This book presents the design and operation of DC wind systems and their integration into power grids. The chapters give an in-depth discussion on turbine conversion systems that have been adapted for DC grids and address characteristics of wind turbines when converting kinetic wind energy to electrical energy, components associated with DC systems, and the design and analysis of DC grids. Additionally, the performance of medium voltage DC (MVDC) array grid and high voltage DC (HVDC) transmission grid connected via an offshore substation with DC/DC converters are also addressed. The book examines multiphase hybrid excitation generator systems for wind turbines and discusses its design and operation for all DC systems. The book provides an insight into the state-of-the-art technological advancements for existing and futuristic wind generation schemes, and provides materials that will allow students, researchers, academics, and practicing engineers to learn, expand and complement their expertise.

Book Description
Almost from the onset of the development of wind energy conversion systems (WECS), it was known that variable-speed operation of the turbine would maximize energy capture. This study was commissioned to assess the cost, efficiency gain, reduction of the cost of energy (COE), and other operating implications of converting the existing hardware of a modern fixed-speed wind energy conversion system to variable-speed operation. The purpose of this study was to develop a preliminary design for the hardware required to allow variable-speed operation using a doubly-fed generator with an existing fixed-speed wind turbine design. The turbine selected for this study is the AWT-26 designed and built by Advanced Wind Turbines Inc. of Redmond, Washington. The lowest projected COE using this variable-speed generation system is projected to be $0.0499/kWh, compared to the lowest possible COE with fixed-speed generation which is projected to be $0.0546/kWh. This translates into a 8.6% reduction of the COE using this variable-speed generation option. The preliminary system design has advanced to where the printed circuit boards can be physically laid out based on the schematics and the system software can be written based on the control flow-charts. The core of hardware and software has been proven to be successful in earlier versions of VSG systems. The body of this report presents the results of the VSWG system development. Operation under normal and fault conditions is described in detail, the system performance for variable-speed operation is estimated and compared to the original fixed-speed system performance, and specifications for all system components (generator, power electronic converter, and system controller) are given. Costs for all components are estimated, and incremental system cost is compared to incremental energy production. Finally, operational features of the VSWG which are not available in the existing FSWG system are outlined.
