Non-destructive examination of turbine and generator components experience with mechanized examination techniques

摘要

Turbine and generator shafts are highly-stressed components of turbine-generator sets. Examination techniques for rotating turbine-generator set components were the focus of further development efforts following a case of severe damage in the 1980's. Investigation of service lifetimes of turbine components gained considerably in importance. Siemens Power Generation Group (KWU) has developed a concept for service life analysis of highly-stressed turbine components which takes account of factors such as year of manufacture, i.e. the forging process, materials and service conditions to enable power plant operators to initiate timely actions to ensure safe and reliable plant operation.
