experience, the information presented in the book is designed to inform the reader about actual machine operational problems and failure modes that occur in generating stations and other types of facilities. Readers will find very detailed coverage of:. Design and construction of generators and auxiliary systems. Generator operation, including interaction with the grid. Monitoring, diagnostics, and protection of turbo-generators. Inspection practices, including stator, rotor, and auxiliary systems. Ideas for improving plant reliability and reducing costs and electrical failures. Maintenance testing, including electrical and nondestructive examinationOperation and Maintenance of Large Turbo-Generators comes filled with photos and graphs, commonly used inspection forms, and extensive references for each topic. It is an indispensable resource for anyone involved in the design, construction, protection, operation, maintenance, and troubleshooting of large generators in generating stations and industrial power facilities. The book is also an excellent learning tool for students, consultants, and design engineers. |
