Review

Hydro generators have been an essential part of the world's electrical supply for over 100 years and have a power output up to about 1,000 MW. To our knowledge, this is the first book that is specifically focused on how to operate, test, and maintain such machines. This book has a similar format to the well-regarded book Handbook of Large Turbo Generator Operation and Maintenance, written by two of the authors of the hydro generator book (Kerszenbaum and Klempner). This book will be of interest to readers of this magazine because there is a significant focus on the electrical insulation used in hydro generator rotor and stator windings. The main authors are Mottershead and Bomben, who have extensive experience in hydro generator design and operation, respectively. These authors are well known from published papers and their work on IEEE standards working groups. Bomben is currently the chair of the Board of Governors for the IEEE Electrical Insulation Conference.Handbook of Large Hydro Generators: Operation and Maintenance is a practical handbook for engineers and maintenance staff responsible for the upkeep of large salient-pole hydro generators and pumped-storage generators. It first presents the physics and design of large vertical salient-pole generators. The book then offers readers real-world experience, problem description, and solutions, while teaching them about the design, modernization, inspections, maintenance, and operation of salient-pole machines. One of the best aspects are the explanations of what to look for when doing inspections of the rotor and stators. The book also covers generator protection and auxiliary systems inspection. The final two chapters are dedicated to maintenance and testing, and maintenance philosophies, upgrades, and uprates. Perhaps in a future version of this book they will discuss how to repair hydro generators in more detail. The handbook includes over 420 full color photos and 180 illustrations, forms, and tables to complement the topics covered in the chapters. Every hydro generating plant in the world should have a copy of this book.- John Shea, IEEE DEIS Magazine Book Reviews
