Distributed Photovoltaic Grid Transformers

by Hemchandra Madhusudan Shertukde

Overview

The demand for alternative energy sources fuels the need for electric power and controls engineers to possess a practical understanding of transformers suitable for solar energy. Meeting that need, Distributed Photovoltaic Grid Transformers begins by explaining the basic theory behind transformers in the solar power arena, and then progresses to describe the development, manufacture, and sale of distributed photovoltaic (PV) grid transformers, which help boost the electric DC voltage (generally at 30 volts) harnessed by a PV panel to a higher level (generally at 115 volts or higher) once it is inverted to the AC voltage form by the inverter circuit.

Packed with real-life scenarios and case studies from around the globe, Distributed Photovoltaic Grid Transformers covers the key design, operation, and maintenance aspects of transformers suitable for solar energy. Topics include islanding, voltage flicker, voltage operating range, frequency and power factor variation, and waveform distortion. Multiple homework questions are featured in each chapter. A solutions manual and downloadable content, such as illustrated examples, are available with qualifying course adoption.

Editorial Reviews

"Mr. Shertukde has taken the typical jargon and simplified it, allowing even the newcomer to get acquainted with the subject matter. Transformers as a science can be complicated enough and applying them to a fast-growing field to support the photovoltaic industry creates additional challenges. This book helps to clearly expose some of these challenges and guides the designer, developer, and even the end user to ask the right questions."
—Vladimir Gulkarov, Director of Engineering, Smiths Power, Santa Ana, California, USA

"An important feature of this book is the breadth of topics covered regarding issues related to DPV-GT design considerations … The author has gathered knowledge from a variety of industry standards and technical project reports, compiled and presented it in a concise and easy to read form. The book presents a comprehensive look into design, safety and protection issues related to DPV-GTs. This book should appeal to both practicing power/utility Engineers as well as students of power systems."
—Ajit Thatte, Formerly CEO Enkay Technologies ( India) Ltd. Presently Independent Management Consultant & Visiting Faculty to Management Institutes

"This pioneering book is focusing on design, manufacture, application and operation of the distributed photovoltaic grid transformers (DPV-GTs). … With rapidly developing solar-based power generation this work is an important contribution to the efforts to deliver engineering solutions for the photovoltaic grid.
—Waldemar Ziomek, CG Power Systems Canada Inc
