Available in PDF, EPUB and Kindle. Book excerpt: The Gearbox Reliability Collaborative (GRC) investigates root causes of wind turbine gearbox premature failures and validates design assumptions that affect gearbox reliability using a combined testing and modeling approach. Knowledge gained from the testing and modeling of the GRC gearboxes builds an understanding of how the selected loads and events translate into internal responses of three-point mounted gearboxes. This paper presents some testing and modeling results of the GRC research during Phase 1 and 2. Non-torque loads from the rotor including shaft bending and thrust, traditionally assumed to be uncoupled with gearbox, affect gear and bearing loads and resulting gearbox responses. Bearing clearance increases bearing loads and causes cyclic loading, which could contribute to a reduced bearing life. Including flexibilities of key drivetrain subcomponents is important in order to reproduce the measured gearbox response during the tests using modeling approaches.

Available in PDF, EPUB and Kindle. Book excerpt: Gearbox failures have a significant impact on the cost of wind farm operations. To help minimize gearbox failures, in 2007 the National Renewable Energy Laboratory (NREL) initiated the Gearbox Reliability Collaborative (GRC), which consists of manufacturers, owners, researchers, and consultants. Based on all the lessons learned from the past five years, the GRC has now produced a new and improveddesign, which is projected to yield an operating lifetime of 12 years, more than triple that of the previous redesigned gearbox. The GRC findings will result in increased gearbox reliability and an overall reduction in the cost of wind energy.

This book was released on 2010 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Most turbines in the market today follow a modular configuration comprised of a main shaft, gearbox, high speed shaft, and generator. The gearbox has the important task of increasing the slow rotor speeds to meet the electromechanical requirements of the electromechanical. These gearboxes are commonly composed of a planetary stage and several parallel shaft stages. The planetary, or epicyclical, design of the gearbox is a feature of the design that has many advantages compared to the traditional parallel shaft arrangement. Among these are that higher gear ratios can be achieved in a single stage, they are capable to carrying higher loads, and they require less space than the traditional parallel shaft arrangement. For this reason, planetary gearboxes they are commonly used in the first stage of the wind turbine gearboxes. However, planetary stages are more complex than the typical parallel shaft arrangement, and can be affected by deflection in the planet carrier, annulus deformations and bearing clearances. Unanticipated levels of these motions can reduce their life expectancy. This paper gives a brief overview of a subset of the experimental efforts, data, and analysis of the GRC project focusing on the planet carrier deformation.

Book excerpt: The revised edition presents, extends, and updates a thorough analysis of the factors that cause and accelerate the aging of conductive and insulating materials of which transmission and distribution electrical apparatus is made. New sections in the second edition summarize the issues of the aging, reliability, and safety of electrical apparatus, as well as supporting equipment in the field of generating renewable energy (solar, wind, tide, and wave power). When exposed to atmospheric corrosive gases and fluids, contaminants, high and low temperatures, vibrations, and other internal and external impacts, these systems deteriorate; eventually the ability of the apparatus to function properly is destroyed. In the modern world of "green energy", the equipment providing clean, electrical energy needs to be properly maintained in order to prevent premature failure. The book’s purpose is to help find the proper ways to slow down the aging of electrical apparatus, improve its performance, and extend the life of power generation, transmission, and distribution equipment.

Available in PDF, EPUB and Kindle. Book excerpt: NREL has initiated the Gearbox Reliability Collaborative (GRC) to investigate the root cause of the low wind turbine gearbox reliability. The GRC follows a multi-pronged approach based on a collaborative of manufacturers, owners, researchers and consultants. The project combines analysis, field testing, dynamometer testing, condition monitoring, and the development and population of a gearbox failure database. At the core of the project are two 750kW gearboxes that have been redesigned and rebuilt so that they are representative of the multi-megawatt gearbox topology currently used in the industry. These gearboxes are heavily instrumented and are tested in the field and on the dynamometer. This report discusses the bearing calibrations of the gearboxes.

Book excerpt: Since early recorded history, people have been harnessing the energy of the wind. In the United States in the late 19th century, settlers began using windmills to pump water for farms and ranches, and later, to generate electricity for homes and industry. Industrialism led to a gradual decline in the use of windmills. The steam engine replaced European water-pumping windmills, and in the 1930s, the Rural Electrification Administration's programs brought inexpensive electric power to most rural areas in the United States. However, industrialization also sparked the development of larger windmills, wind turbines, to generate electricity.

Available in PDF, EPUB and Kindle. Book excerpt: Our future hinges on a set of elements that few of us have even heard of. In this surprising and revealing book, David S. Abraham unveils what rare metals are and why our electronic gadgets, the most powerful armies, and indeed the fate of our planet depend on them. These metals have become the building blocks of modern society; their properties are now essential for nearly all our electronic, military, and “green” technologies. But their growing use is not without environmental, economic, and geopolitical consequences. Abraham traces these elements’ hidden paths from mines to our living rooms, from the remote hills of China to the frozen Gulf of Finland, providing vivid accounts of those who produce, trade, and rely on rare metals. He argues that these materials are increasingly playing a significant role in global affairs, conferring strength to countries and companies that can ensure sustainable supplies. Just as oil, iron, and bronze revolutionized previous eras, so too will these metals. The challenges this book reveals, and the plans it proposes, make it essential reading for our rare metal age.
