  • This book is concerned with the subject of Wind Energy, as a source of clean and renewable and free for all. The need for this type of book is very well documented, the current consumption of energy is unsustainable and humans have to change their habits and or utilise this source, but there is so much work before we can rely completely on renewable energy. This book aims to describe the fundamentals of wind energy and the pertinent parameters that control the amount of energy available from a given wind turbine. Coal fuelled the industrial revolution in the 18th and 19th century.

  • From the principles of electrical engineering it is known that the 3-phase quantities of the 3-phase AC machines can be summarized to complex vectors. These vectors can be represented in Cartesian coordinate systems, which are particularly chosen to suitable render the physical relations of the machines. These are the field-orientated coordinate system for the 3- phase AC drive technology or the grid voltage orientated coordinate system for generator systems.

  • The objective of this book is to acquaint the reader with explosive driven pulsed power devices, theory and applications. This includes those devices that convert the chemical energy stored in high explosives into electrical energy and that use shock waves generated by the explosives to release the energy stored in ferromagnetic or ferroelectric materials in the form of electrical energy. The reader might well ask why one should use explosive driven pulsed power for any application, since it is inherently single shot in nature.

  • This book analyses the key issues of the offshore wind farm's energy transmission and grid integration infrastructure. But, for this purpose, there are not evaluated all the electric configurations. In the present book is deeply evaluated a representative case. This representative case is built starting from three generic characteristics of an offshore wind farm: the rated power, the distance to shore and the average wind speed of the location.

  • INTRODUCTION Part I discussed the basics of industrial servo drives from a hardware point of view. Physical parameters and practical applications were discussed. Part II repeats some of the things in Part I but from a mathematical point of view. The advanced application of industrial servo drives requires the use of differential equations to describe mechanical, electrical, and fluid systems. As applied to servo drives there are numerous academic techniques to analyze these systems (e.g., root locus, Nyquist diagrams, etc.).

  • Around 120,000 passengers benefit from the service provided by three-wheel SAFA tempos on a daily basis. Kathmandu perhaps has more number of battery-powered commuter electric vehicles than any other urban centers in the world. The EV drivers get NRs. 4,000 to NRs. 5, 000 per month. The tempo owners need NRs. 6000 – 7000 per months for charging and NRs.10, 000 per month for depreciation of the batteries. When the batteries are new, the SAFA Tempos can get a range of 70 or more kms. But, due to the aging, the capacity of the battery is reduced and the SAFA...

  • To accurately estimate energy savings attributable to the ENERGY STAR program, and target future efforts, current data are needed on the extent to which each type of office equipment is turned off or successfully enters low power mode when idle. Combined with measurements of the energy used in each power state, we can estimate typical unit energy consumption (UEC), which, combined with number of units currently in use, provides an estimate of total energy use, and program savings (Webber, Brown et al. 2002). In our ongoing technical support of ...
