Abstract:

A discussion of the approaches to, and benefits of, windmill tip-speed ratio (TSR) control is presented. Rotational speed regulation via load-controlled impedance matching is identified as the most efficient control method. An all-mechanical, self-powered windmill TSR controller using this method is presented with a discussion of its operation and wind tunnel test results. The controller, which is applicable to a variety of windmill/load combinations, also provides for rotor start-up and for shutdown in high winds. A design methodology is presented and used to design a controller for a windmil

Abstract:

An extension of the Guerrero et al. (2010) net present value (NPV) analysis using real options analysis (ROA) is offered to improve machinery replacement decisions. Specifically, the feasibilities of replacing natural gas irrigation systems with either electric or hybrid (electric/wind) systems are evaluated. Results indicate NPV and ROA criteria can yield opposite decisions depending on the stochastic nature of the parameters, reversibility of the investment, and flexibility of investment timing. For policy, NPV results indicate that replacing natural gas with a hybrid is on the cusp of being

Abstract:

The American, Charles Brush is often credited with being the first person to use a wind powered machine to generate electricity, which operated for the first time during the winter of 1887. However, earlier in July 1887, Professor James Blyth, a Scottish academic of Anderson's College, Glasgow (which later became Strathclyde University) was undertaking very similar experiments to Brush, which culminated in a UK patent in 1891. Likewise the Dane, Poul La Cour, is known to have constructed relatively advanced wind turbines throughout the 1890s, which were also used to generate electricity which

Abstract:

Dynamic stall is an aerodynamic phenomenon that may occur when an airfoil is subjected to rapid, cyclical changes in angle of attack with respect to the incident ambient flow. This phenomenon can often produce repeated and significant changes in lift and moment coefficients within very short time frames, which manifest as severe and rapid changes in structural loads. Rotorcraft such as helicopters and wind turbines are particularly susceptible to dynamic stall, which is a highly undesirable operating condition. The condition plays a part in limiting the forward speed of a helicopter whilst als

Abstract:

In this work, the concept of an energy conversion system for wind turbines based on the modified permanent magnet synchronous generator (PMSG) is presented. In the generator, a pair of three-phase windings is used, one of which is connected in a “star” and the second in a “delta” configuration. At the outputs of both windings, two six-pulse uncontrolled (diode) rectifiers are included. These rectifiers are mutually coupled by a specially designed pulse transformer, whose primary winding is powered by the power electronics converter—the so-called “current modulator”—which, in this case, operate

Abstract:

Research in renewable and clean energy has reached an unprecedented magnitude owing to the growing concerns over environmental hazards caused by the traditional fuels. In this regard, solar, wind and tidal energies are considered to meet large scale energy requirements. Small, stand-alone electronic devices which are growing in numbers in next generation smart cities, can be powered by scavenging energy from sources which would otherwise remain unused, such as mechanical vibrations. The source of mechanical vibration could have diverse origins, ranging from vibrations of machines to flow of wi

In this article, hybrid wind-diesel system is powered with a genetically tuned fuzzy controlled flywheel for improving its frequency control. Flywheel is interfaced with the system through an electrical machine (generator/motor) and an electronic converter for synchronization. Fuzzy logic controller for the flywheel is designed in such a way that it continuously controls the system frequency and simultaneously satisfies the operational constraints of flywheel. Fuzzy logic controller is optimized by genetically tuning its membership functions. Regulated variable based on frequency deviation of

Abstract:

Chapter 14 investigates the archaeology, technology, and restoration of the Betty’s Hope north windmill. Archaeological excavations and restoration work were conducted from 1988 to 1995. Today, 90 stone towers are all that remain of the windmills scattered across Antigua’s landscape. This project initiated archaeological research at Betty’s Hope as well as cultural heritage management of the site. As one of the largest and most lucrative estates on Antigua, Betty’s Hope could afford two windmills to crush the sugar cane by harnessing wind power and utilizing the horizontal three-roller system. The mid-nineteenth century witnessed the conversion to steam-powered at Betty’s Hope. Restoration efforts included replacing parts of the original stone floor, old hard wood beams, masonry, cap house, arms, and machinery.

Abstract:

Converting wind energy into a useful form of energy is one of the fastest growing alternative sources of energy in the present and foreseeable future. At the end of 2009, worldwide nameplate capacity of wind-powered generators was 159 gigawatts (GW). Energy production at onshore, near shore and offshore locations was 340 TWh, which is about 2% of worldwide electricity usage, and has doubled in the past three years and will continue to grow substantially. This growth comprises not only more wind farms, but wind mills with more capacity as well [1–3]. To achieve this growth, (heavy) lift compani

Abstract:

All over the world huge masses of gas are compressed in a number of storage stations to compensate seasonal fluctuations of the users’ demand versus the methane extraction from geological deposits. In the great majority of such plants, turbo-compressors are used, namely centrifugal machines. Since in this kind of machines compression is essentially adiabatic, gas temperature rises up even to dangerous values. Natural gas cannot be injected into the reservoirs too hot without risk of geological damage, so often an after-cooler has to be provided. Natural gas compressors are driven by gas turbin

Abstract:

The promise of cheap and widely available 3D printers may be one of the best and worst aspects of Additive Manufacturing (AM). A non-technical consumer may pay significantly more for a 3D printer with “no assembly required”. Since it is reasonable to assume that they may not understand how the printer works and what will come out of it, they may wind up returning it because it does not meet their expectations. While consumers are starting to use 3D printers, designers in industry are utilizing Rapid Prototyping (RP) machines to manufacture final products in addition to prototypes. Designers wi
