This book was released on 2019-01-25 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Exponential growth of the global wind turbine market has led to a significant increase in the capacity of wind turbine generators. Modern turbines require higher support structures as higher wind speeds combined with longer blades are necessary to increase their generating capacity. The standard 80-90 m tower is thus not economically viable anymore. Transportation logistics of large steel towers has led to concrete towers becoming a viable option. There are currently no design codes dealing exclusively with the design of concrete wind turbine towers. The aim of this project is to investigate and highlight important aspects of the design process of a normally reinforced high strength concrete wind turbine tower. The tower was designed using nonlinear finite element modelling as a design tool to accurately design the tower for various loads and load cases. An analytical design method was developed that can be used in the preliminary design stage. Finally, the importance of the soil-structure interaction was investigated through a sensitivity analysis.

Download or read book Concrete Structures for Wind Turbines written by Jürgen Grünberg and published by John Wiley & Sons. This book was released on 2013-09-10 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: The wind energy industry in Germany has an excellent global standing when it comes to the development and construction of wind turbines. Germany currently represents the world's largest market for wind energy. The ongoing development of ever more powerful wind turbines plus additional requirements for the design and construction of their offshore foundation structures exceeds the actual experiences gained so far in the various disciplines concerned. This book gives a comprehensive overview for planning and structural design analysis of reinforced concrete and pre-stressed concrete wind turbine towers for both, onshore and offshore wind turbines. Wind turbines represent structures subjected to highly dynamic loading patterns. Therefore, for the design of loadbearing structures, fatigue effects - and not just maximum loads - are extremely important, in particular in the connections and joints of concrete and hybrid structures. There multi-axial stress conditions occure which so far are not covered by the design codes. The specific actions, the nonlinear behaviour and modeling for the structural analysis are explained. Design and verification with a focus on fatigue are adressed. The chapter Manufacturing includes hybrid structures, segmental construction of pre-stressed concrete towers and offshore wind turbine foundations. Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

Download or read book South Africa Wind Energy Barriers written by Richard Ganter and published by Diplomica Verlag. This book was released on 2011-04 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rapid adoption of wind energy in the renewable energy mix can be seen in many industrialized nations in the past decade, in particular the need to agreed greenhouse gas reduction and stable energy supply are seen as a sound vision for a sustainable energy policy’. In an emerging market such as South Africa there are abundant renewable resources including wind energy, however there is low adoption observed to date. This study investigates barriers to entry in the South African wind energy sector and what the priorities are to remove such barriers for successful deployment of wind technology. Therefore, it was required to examine successful deployment of wind energy in the European Union and how such barriers were removed; this was set in the current status of the renewable energy sector and existing barriers in South Africa. It was necessary to gain insight of the inter-related issues on opening a traditional fossil fuel based energy market to a transitional implementation of renewable energy provisioning, considering the current utility monopoly based energy landscape in South Africa.

Download or read book South Africa s Energy Transition written by Tobias Bischof-Niemz and published by Routledge. This book was released on 2018-07-11 with total page 128 pages. Available in PDF, EPUB and Kindle. Book excerpt: South Africa’s energy transition has become a highly topical, emotive and politically contentious topic. Taking a systems perspective, this book offers an evidence-based roadmap for such a transition and debunks many of the myths raised about the risks of a renewable-energy-led electricity mix. Owing to its formidable solar and wind resources, South Africa has an almost unparalleled opportunity to turn solar photovoltaic and onshore wind generators into the country’s power generation workhorses – a role hitherto played by coal. This book shows that a renewables-led mix will not only provide the lowest cost, but will also create more jobs than any of the alternatives currently under consideration. In addition, it offers a glimpse of how South Africa’s low-cost and decarbonised electricity system can power a competitive industrial economy, an electric-mobility revolution and, in the long run, create new export opportunities. This book will be of great interest to energy industry practitioners, as well as students and scholars of energy policy and politics, environmental economics and sustainable development.

Available in PDF, EPUB and Kindle. Book excerpt: Wind energy has been placed at the centre of the South African Government's Renewable Energy Independent Producer Programme (REIPPP) with the purpose of addressing electricity capacity deficits and poor service delivery. In doing so, substantial wind farm development has been proposed for the Western, Eastern and Northern Cape of South Africa, with several projects already underway. Wind energy, from a technological standpoint, is regarded as a mature form of renewable energy. However, much of the wind turbine geotechnical experience was gained in the temperate climate of the Northern Hemisphere, where soil conditions differ significantly from those of South Africa. Simultaneously, although mature, wind energy is a novel field in South Africa. Therefore, this study sought the need bridge the gap between local South African soil conditions and international wind energy experience. It was against this backdrop that the following study was initiated, which aimed to provide insight into the site-specific geotechnical design of foundations for wind turbine structures. In doing so, this major objective was divided into four minor objectives, each contributing a major theme to the study, the key points of which are summarised below. It should be noted that the following study was limited to three-blade wind turbines mounted on conical tubular steel towers with shallow foundations.

Download or read book Concrete and Sustainability written by Per Jahren and published by CRC Press. This book was released on 2013-07-16 with total page 437 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concrete is by far the most common building material— accounting for twice the volume of all other such materials combined. With such a huge global economic impact, the industry has a correspondingly considerable responsibility to use it sustainably. Written by experts who pioneered research into environmental issues and concrete, Concrete and Sustainability examines the sustainability issues of the world’s main construction material and proposes attainable solutions. It provides a complete overview of the topic and tackles the complexity of the challenges from different angles. This book offers new data regarding the social and economic importance of concrete and proposes a discussion centered on a holistic approach in terms of resource availability, technical viability, economic feasibility, and environmental compatibility. The authors attribute a growing worldwide concern and understanding of sustainability issues, and an increased focus on climate change as the catalyst in this process. Instead of offering detailed technical advice or recommendations on sustainable issues, they provide examples showcasing sustainability efforts taking place in the concrete environment worldwide. The book includes examples and ideas for solutions from a large number of countries from across the globe. It presents a holistic and more complete overview of the emission and absorption topic, takes a look at the challenges from a combined old and new world viewing platform and offers an exploration of issues from a social and economic perspective. Concrete and Sustainability details the various rules and regulations that the industry is facing, discusses the various environmental challenges, and explores its impact. As emission, absorptions, and recycling have been the most central elements of discussion in the cement and concrete environment so far, these topics each receive their own chapters. This book also discusses other issues of concern within the various platforms in the industry, as well as future developments, and provides a comprehensive reference list.
