Electromagnetic Analysis and Condition Monitoring of Synchronous Generators

Discover an insightful and complete overview of electromagnetic analysis and fault diagnosis in large synchronous generators

In Electromagnetic Analysis and Condition Monitoring of Synchronous Generators, a team of distinguished engineers delivers a comprehensive review of the electromagnetic analysis and fault diagnosis of synchronous generators. Beginning with an introduction to several types of synchronous machine structures, the authors move on to the most common faults found in synchronous generators and their impacts on performance.

The book includes coverage of different modeling tools, including the finite element method, winding function, and magnetic equivalent circuit, as well as various types of health monitoring systems focusing on the magnetic field, voltage, current, shaft flux, and vibration. Finally, Electromagnetic Analysis and Condition Monitoring of Synchronous Generators covers signal processing tools that can help identify hidden patterns caused by faults and machine learning tools enabling automated condition monitoring.

The book also includes:
_ A thorough introduction to condition monitoring in electric machines and its importance to synchronous generators
_ Comprehensive explorations of the classification of synchronous generators, including armature arrangement, machine construction, and applications
_ Practical discussions of different types of electrical and mechanical faults in synchronous generators, including short circuit faults, eccentricity faults, misalignment, core-related faults, and broken damper bar faults
_ In-depth examinations of the modeling of healthy and faulty synchronous generators, including analytical and numerical methods

Perfect for engineers working in electrical machine analysis, maintenance, and fault detection, Electromagnetic Analysis and Condition Monitoring of SynchronousGenerators is also an indispensable resource for professors and students in electrical power engineering.
