This book offers introduction of Power system protection relay characteristics, operational behavior of distance relay and proposed simulation based technique for fault detection. In recent years, we have seen several catastrophic failures of power systems throughout the world. The usual scenario of such events is that the power system is in a stressed state, followed by faults on critical facilities, followed by unanticipated tripping of other facilities, finally leading to system breakup and blackouts. Distance relay plays an important role in the protection of transmission lines. In conventional transmission line protection, a three ¿ zone stepped directional distance system is used to provide the primary as well as remote backup protection. However, accuracy of this measurement may be affected by the power disturbances such as power swings and switching actions, over loading resulting load encroachment. The quality of this measurement may cause mal-operation of distance relays which in turn may affect the reliability of the whole protective scheme. This book describe how Simulink/MATLAB simulator under L-G faults conditions detects the distance relay third zone malfunctioning.

The importance of protection of power system is well known in various engineering fields. The book is structured to cover the key aspects of generator protection system. The book provides brief introductory part of various faults associated with generator. The main focus of this book is numerical relay configuration and setting. In later part of book covers relay testing overview. This makes the understanding of the subject more clear and makes it more interesting. This book will be very useful not only to the students but also to the subject teachers.

Examines a network of intellectuals who attempted to re-imagine and reshape the relationship between the U.S. and India.
