Fault Location on Transmission and Distribution Lines: Principles and Applications

Covers both fundamental theory and state-of-the-art fault location algorithms for determining the location of faults in transmission and distribution lines

Fault Location on Transmission and Distribution Lines provides practical guidance on the applications of fault location algorithms in transmission and distribution lines. A single-volume compilation of ten years of research, this authoritative resource helps readers quickly determine the precise location of faults, analyze data to understand the cause of the fault, expedite service restoration, and improve overall power system performance and reliability. The authors describe the theory and derivation of fault location algorithms, explain the rationale behind the development of each algorithm, and illustrate their real-world application. Throughout the text, case studies on utility fault data are presented to clearly demonstrate all theoretical concepts.

The text begins by introducing the subject of faults, the aim and importance of fault location, and the concept of symmetrical components for fault calculations. It discusses the two main types of fault location algorithms and discusses the theory, input data requirements, and the sources of error in these algorithms. This book shows the additional benefits of fault location such as evaluating the system response, verifying relay settings, and validating the power system model. This comprehensive and up-to-date volume:

• Describes impedance-based and traveling-wave fault location algorithms
• Helps readers determine the best fault-locating algorithm for their system
• Contains several examples that show how to apply fault location algorithms
• Explains additional benefits of fault location to improve power system reliability
• Offers detailed analysis of voltage and current waveforms recorded by digital relays, digital fault recorders, and other electronic devices
• Contains numerous tables, illustrations, photographs, and case studies of both simulated and actual fault event data
• Includes fault location codes in MATLAB available via a companion website

Fault Location on Transmission and Distribution Lines: Principles and Applications is essential reading for upper-level undergraduate and graduate students in Electrical Engineering programs, and is a valuable reference for practicing engineers, technicians, and researchers working in the areas of power system protection and automation.
