Introduction to Electrical Power and Power Electronics By Mukund R. Patel

Introduction to Electrical Power and Power Electronics By Mukund R. Patel
Preface : 
The United States, Canada, the United Kingdom, and many other countries are presently experiencing a shortage of power engineers. The shortage is expected to get worse in the United States, where about 45% of the utility power engineers will become eligible to retire before 2020. They would require about 7000 new power engineering graduates to replace them and about an equal number in the supporting industries. At the same time, many countries are making huge investments in building new power plants and power grids that will require even more power engineers to serve the industry. It is for this trend that university students are now once again getting attracted to the electrical power programs. No other technology has brought a greater change in the electrical power industry and still holding the potential of bringing future improvements than power electronics. The power electronics equipment prices have declined to about 1/10 since the late 1980s, fueling a rapid growth in their applications throughout the power industry. Large cruise ships’ power plant ratings approach 100 MWe since they use electric propulsion with power electronics in abundance. The navies of the world have started changing from mechanical propulsion to electric propulsion with power electronics for the numerous benefits they offer. With high-power combat weaponsonboard, they will need even larger power plants in size comparable to those on land. Until now, there has been no single book available that covered the entire scope of electrical power and power electronics systems. Traditional books on power systems focused on high voltage transmission, in which only a handful of power engineers get involved. A vast majority of power engineers work in cities, towns, large factories, steel mills, commercial and institutional buildings, refineries, data centers, railways, shipping ports, commercial and navy ships, etc. They mostly deal with power taken from the utility company or self-generated mostly for running motors and other loads via transformers, cables, and protection devices such as fuses and circuit breakers. They also routinely deal with batteries of various electrochemistries, power electronics converters of all kinds, variable-frequency motor drives, etc. This book is the first comprehensive volume of its kind that focuses on all of these topics, which are directly relevant to most power engineers on a daily basis. In addition, engineers working in the renewable energy technologies would also find this book useful since the electrical power system for extracting energy from wind and ocean currents is the exact mirror image of the variable frequency motors driving pumps, fans, and ship propellers.
