Hardback. Etat : New. The development of offshore wind power has become a pressing modern energy issue in which the UK is taking a major part, driven by the need to find new electrical power sources, avoiding the use of fossil fuels, in the knowledge of the extensive wind resource available around our islands and the fact that the environmental impact of offshore wind farms is likely to be low. However, there are major problems to solve if offshore wind power is to be realised and these problems revolve around the need to capture energy at a cost per kWh which is competitive with other sources. This depends upon the longevity of the wind turbines which make up offshore wind farms. Their availability, reliability and the efficacy and cost-effectiveness of the maintenance needed to achieve that availability, are essential to improve offshore wind life-cycle costs and the future of this emerging industry. This book intends to address these issues head-on and demonstrate clearly to manufacturers, developers and operators the facts and figures of wind turbine operation and maintenance in the inclement offshore environment, recommending how maintenance should be done to achieve low life-cycle costs.…

However the engineering problems are gradually being solved and there is an appetite to invest in these renewable generation technologies for harsher environments. To some extent the wave and tidal generation industry is following in the wake of the wind industry, particularly learning from the growing experience of offshore wind farm deployment. This book combines wind industry lessons with wave and tidal field knowledge to explore the main reliability and availability issues facing this growing industry. Topics covered include an overview of wave and tidal development; resource; reliability theory relevant to wave and tidal devices; reliability prediction method for wave and tidal devices; practical wave and tidal device reliability; effects of MEC device taxonomy on reliability; availability and its effect on the cost of marine energy; wave and tidal device layout and grid connection; design and testing for wave and tidal devices; operational experience and lessons learnt; monitoring and its effect on operations and maintenance; and overall conclusions. Wave and Tidal Generation Devices: Reliability and availability is essential reading for wave and tidal engineers and researchers and students of renewable energy.…

Hardback. Etat : New. Condition monitoring of engineering plants has increased in importance as engineering processes have become increasingly automated. However, electrical machinery usually receives attention only at infrequent intervals when the plant or the electricity generator is shut down. The economics of industry have been changing, placing ever more emphasis on the importance of reliable operation of the plants. Electronics and software in instrumentation, computers, and digital signal processors have improved our ability to analyse machinery online. Condition monitoring is now being applied to a range of systems from fault-tolerant drives of a few hundred watts to machinery of a few hundred MW in major plants. This book covers a large range of machines and their condition monitoring. This 3rd edition builds on the 2nd edition through a major revision, update of chapters and a comprehensive list of references and standards. Permanent magnet, switched reluctance and other types of machines are now covered, as well as variable speed drive machines and off-line techniques. Contents cover an introduction to condition monitoring; rotating electrical machines; electrical machine construction, operation and failure modes; reliability of machines and typical failure rates; signal processing and instrumentation requirements; on-line temperature monitoring; on-line chemical monitoring; on-line vibration monitoring; on-line current, flux and power monitoring; on-line partial discharge (PD) electrical monitoring; on-line variable speed drive machine monitoring; off-line monitoring; condition-based maintenance and asset management; application of artificial intelligence techniques to CM; and safety, training and qualification. …
