DESCRIPTION
Reliability of turbine generators is important to economic operation of power plants. Approximately 50% of generator failures are caused by stator and rotor windings. Failures of major generator components requires long repair times which results in significant power generation loses. The first step in prevention of generator faults is proper training and education on the winding function, recognition of winding problems and adoption of cost effective maintenance for personnel responsible for generator operation.
OBJECTIVE
The course focuses on large steam and gas turbine driven synchronous generators with cylindrical rotors, rated 11kV and above. Discussion will concentrate on stators and rotors and will cover:
- Winding design and function
- Most winding degradation and failure modes and mechanisms
- Assessment of winding condition from off-line tests and on-line monitoring
- Range of available repair and replacement options
- General guide in preparation of Stator Winding Specification
The course is presented from an end user perspective, rather than that of a machine designer.
WHO SHOULD ATTEND
This course is directed at engineering and maintenance personnel responsible for the purchase, installation, maintenance, testing and repairs of large air-cooled and hydrogen-cooled turbine-generators.
