Development of a Method for Online Monitoring and Diagnostics of Turbine Generators for Increased Reliability and Service Life

Issues in the practical application of continuous monitoring tools for assessing the technical condition and identifying defects of turbine generators are considered. In order to ensure an effective monitoring solution, it is necessary to take a specific approach to individual installations. Particular attention should be paid to the generator “trouble spots,” i.e., important structural elements prone to defects. Using specific examples from diagnostic examination practice, the most typical problems affecting the structural elements of various turbine generators are discussed. The current state of regulatory and technical documentation is analyzed. Inadequacies affecting some existing documents in terms of supporting the needs of operating personnel for solving contemporary problems of online monitoring and diagnostics of turbine generators are noted.
