A large wind farm may consist of several hundred individual wind turbines distributed over an extended area, but the land between the turbines may be used for agricultural or other purposes. For example, Gansu Wind Farm , the largest wind farm in the world, has several thousand turbines. A wind farm may also be located offshore. In a wind farm, individual turbines are interconnected with a medium voltage often Different types of wind turbine generators behave differently during transmission grid disturbances, so extensive modelling of the dynamic electromechanical characteristics of a new wind farm is required by transmission system operators to ensure predictable stable behaviour during system faults.

Thus, these harmonics are within the allowable range of IEEE Data that was determined to be incorrect due to sensor icing or other problems, for example is indicated by Use this data to determine the appropriate Variance MCP relationship between the two sites using three different years of concurrent data: , and What are the slopes and offsets determined from these three different concurrent data sets?

What is the data recovery of the data sets used for the analysis expressed as a percentage of a year worth of data?

What might be the cause of the difference between the results for different years? The results are shown here: Year of Concurrent Data Slope 0. There is some variability between the offsets that were determined. The causes of the variability is unknown but could be due to sensor changes, changes in the ground cover upwind of either site over the four year period or variability in the relationship between the winds at the two locations.

Additionally, the overpasses on the road are only rated for loads tractor trailer plus cargo of 36, kg.

Note that the empty tractor trailer has a mass is 16, kg. The available clearance is 4. The available blade weight is only 20, kg due to the weight of the tractor and trailer. The 4.

It describes economic analysis methods and shows how wind energy can be compared with conventional forms of generation. Chapter 12 describes the environmental aspects of wind energy generation.

Finally, a new appendix C has been added. This appendix provides an overview of some of the data analysis techniques that are commonly used in wind turbine design and use. This book is intended primarily as a textbook for engineering students and for professionals in related fields who are just getting into wind energy. It is also intended to be used by anyone with a good background in math and physics who wants to gain familiarity with the subject.

It should be useful for those interested in wind turbine design per se. For others, it should provide xii Preface enough understanding of the underlying principles of wind turbine operation and design to appreciate more fully those aspects in which they have a particular interest.

These areas include turbine siting, grid integration, environmental issues, economics, and public policy. The study of wind energy spans such a wide range of fields. Since it is likely that many readers will not have a background in all of them, most of the chapters include some introductory material. Where appropriate, the reader is referred to other sources for more details. Acknowledgments We would like to acknowledge the late Professor William Heronemus, founder of the renewable energy program at the University of Massachusetts.

Without his vision and tenacity, this program would never have existed, and this book would never have been written. We are also indebted to the numerous staff and students, past and present, at the University of Massachusetts who have contributed to this program. In addition, we appreciate the contribution of Rolf Niemeyer for looking into the sources of information on the earliest windmills and Tulsi Vembu for his editing.

Finally, we would like to acknowledge the support of our families: our wives Joanne, Suzanne, and Anne and our sons Nate, Gerry, and Ned and Josh and Brian , who have all inspired our work.

The advent of the steam engine, followed by the appearance of other technologies for converting fossil fuels to useful energy, would seem to have forever relegated to insignificance the role of the wind in energy generation. In fact, by the mid s that appeared to be what had already happened. By the late s, however, the first signs of a reversal could be discerned, and by the early s it was becoming apparent that a fundamental reversal was underway.

That decade saw a strong resurgence in the worldwide wind energy industry, with installed capacity increasing over five-fold.

The s were also marked by a shift to large, megawatt-sized wind turbines, a reduction and consolidation in wind turbine manufacture, and the actual development of offshore wind power see McGowan and Connors, During the start of the 21st century this trend has continued, with European countries and manufacturers leading the increase via government policies focused on developing domestic sustainable energy supplies and reducing pollutant emissions.

To understand what was happening, it is necessary to consider five main factors. First of all there was a need. Second, there was the potential.

Wind exists everywhere on the earth, and in some places with considerable energy density. Wind had been widely used in the past, for mechanical power as well as transportation. Certainly, it was conceivable to use it again. Third, there was the technological capacity.

In particular, there had been developments in other fields, which, when applied to wind turbines, could revolutionize they way they could be used. These first three factors were necessary to foster the re-emergence of wind energy, but not sufficient.
