The electric power systems around the world are going through a period of significant changes resulting from requirements for improvements in the reliability of the transmission and distribution systems and reduction in the number and duration of power outages.
The developments in protection, automation and communications technologies are making distribution automation an important tool that can help the specialists in our industry meet the above requirements. This book is a timely publication covering all the major components of a distribution automation system.
The 352 pages of the book are arranged in twelve chapters written by different authors and edited by Biswarup Das, a professor at the Department of Electrical Engineering, Indian Institute of Technology Roorkee, India where his research interests include distribution system analysis and automation, FACTS, HVDC, digital protection of power systems, power quality and power system harmonics, and distributed generation. He serves as an Associate Editor of IET Generation, Transmission & Distribution and as an editor of IEEE Transactions on Sustainable Energy.

The first chapter of the book is dedicated to an essential component of any distribution automation system - the communication systems. It analyzes the importance of communication technology in distribution automation and introduces the communication system model. This is followed by the description of different communication technologies and transmission media.
The next two chapters focus on load flow and short circuit analysis. Load flow analysis for balanced and unbalanced distribution systems are considered, while the short circuit analysis covers the different types of faults in radial or meshed distribution systems.
Chapter 4 looks at the issues of distribution systems state estimation from the point of view of suitability of different state estimation methods for distribution system applications. 

The next three chapters concentrate on distribution automation applications related to feeder reconfiguration for loss reduction and load balancing, together with service restoration.
Volt-VAR control is the subject of Chapter 8. It is presented from the point of view of voltage standards and describes local and centralized control methods using different control principles. The impact of distributed energy resources is also considered.
Chapter 9 focuses on fault location in distribution systems. It describes different fault location methods, as well as a fault location algorithm together with sample calculations.

The next chapter concentrates on fault detection and fault type identification in distribution networks. It discusses methods for fault classification and introduces the concept of Adaptive Network based Fuzzy Inference System (ANFIS). A few other methods are also included.
Chapter 11 is focused on economic and cost benefit analysis of distribution automation systems. The approach to cost - benefit analysis is presented using an actual distribution automation system.

The last chapter of the book is a case study of the distribution automation system at Enexis - one of the major distribution system operators in The Netherlands.

In summary, this book is an essential source for specialists in the field of electric power systems protection and control. It can be useful for people working on the design of actual distribution automation systems, as well as for researchers and advanced students working on distribution automation related topics.
