Generator Reliability Programs
With over 25 years of servicing steam and gas turbines in the cogeneration and independent power segments, TGM understands the importance of an outage schedule to the financial success of the power plant. TGM has developed a service philosophy of providing customers options to support their availability goals while protecting the reliability of their assets.
It is with this philosophy that TGM has developed our Generator Reliability Program (GRP). We believe it is imperative to inspect the generator as often as the turbine and turbine auxiliaries and, with a frequent and structured inspection and maintenance program, costly unplanned generator outages can be largely avoided.
TGM’s Generator Reliability Program (GRP) consists of three major inspection options built around the turbine inspections; thus the generator never becomes the critical path of the outage unless an outage is planned specifically to address major maintenance on the generator (a stator or rotor rewind, for example):
- GRP 1:This inspection program is designed to fit in a short turbine outage window of 1-2 days
- GRP 2: This inspection program is designed to fit in a 3-4 day turbine outage window
- GRP 3: This inspection is designed to fit in a Major Inspection turbine outage window
The TGM Generator Reliability Program is built on the philosophy that frequent inspections, with varying tests based on the extent of the disassembly, can be used, cumulatively, to provide a good understanding of how the unit is degrading; this way a rehabilitation plan can be planned for future outages instead of extending a current one.
Each of the GRP inspections is an integral building block to the next inspection and, together, they are the basis for the future maintenance of the generator. Done regularly, deterioration of the windings can be predicted, and future major maintenance (rewinds, for example) can be planned.
