In the industry`s growing competitive climate, utilities are seeking ways to tap the economic benefits to be derived from maximizing intervals between major turbine-generator (T-G) inspections and overhauls--while ensuring protection of these assets. EPRI and others have developed a substantial body of technology which addresses many of the condition assessment issues that underlie T-G inspection and overhaul decisions. Examples include remaining life determination of critical components such as rotors and blades. While the initial focus of this technology had previously been to support T-G run-repair-replace decision making, this technology can also serve as a basis for run-inspect decisions. This paper describes EPRI`s initiative to develop and implement a T-G Health Management System. By providing key status reports reflecting the on-line health of critical components, in terms of life consumption, performance degradation and probability of failure, this system will provide a means to justify extending T-G operations between inspections and overhauls.
