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 & 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.
There are many wave and tidal devices under development but as yet
very few are actually in revenue earning production. 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.
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, and 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 revolve around the need to capture this energy
at a cost per kWh which is competitive with other practicable
sources. This will depend upon the longevity of the wind turbines
which make up these offshore wind farms. Their availability,
reliability and the efficacy and costeffectiveness of the
maintenance, needed to achieve that availability, are essential to
improve offshore wind lifecycle costs and the future of this
emerging industry. Offshore Wind Turbines addresses these issues
headon and demonstrates 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 lifecycle costs. The
author is one of the principal international contributors to the
measurement and improvement of wind turbine reliability and this
book is based upon his and colleagues work in the area. This book
will be valuable to wind power production companies, wind turbine
manufacturing companies, wind operation and maintenance engineers,
SCADA and condition monitoring engineers, research students and
final year undergraduate students. This book will also be of
interest to wind turbine technicians and power generation
personnel.
Condition monitoring of engineering plant has increased in
importance as engineering processes are automated and manpower is
reduced. However, electrical machinery receives attention only at
infrequent intervals when plant is shut down and the application of
protective relays to machines has also reduced operator
surveillance. A first edition of Condition Monitoring of Electrical
Machines, written by Tavner and Penman, was published in 1987. The
economics of industry have now changed, as a result of the
privatisation and deregulation of the energy industry, placing
emphasis on the importance of reliable operation of plant,
throughout the whole life cycle, regardless of first cost. The
availability of advanced electronics and software in powerful
instrumentation, computers, and digital signal processors (DSP) has
simplified our ability to instrument and analyse machinery. As a
result condition monitoring is now being applied to a wider range
of systems, from fault-tolerant drives of a few hundred watts in
the aerospace industry, to machinery of a few hundred megawatts in
major capital plant. In this new book the original authors have
been joined by Ran, an expert in power electronics and control, and
Sedding, an expert in the monitoring of electrical insulation
systems. Together the authors have revised and expanded the earlier
book, merging their own experience with that of machine analysts to
bring it up to date. The book is aimed at professional engineers in
the energy, process engineering and manufacturing industries, plus
research workers and students.
