The COMBINED CYCLE Journal and the steering committees of the industry’s leading gas-turbine users groups—including 7F, 501F, 501G, 7EA, 7/9HA, Western Turbine, Frame 6B, 501G, 501D5-D5A, AOG, and V—collaborate to expand the sharing of best practices and lessons learned among owner/operators of large frame and aeroderivative gas turbines. Thirty-five plants listed below participated in the
In the world of power generation there is a significant number of mature frame gas turbines that are the backbone for industrial settings and power generation. There are several well-established user groups that support owner/operators by sharing lessons learned, technical knowledge, and troubleshooting support. It’s critical that these groups maintain a strong presence in the

Challenge. Soon after commissioning, one of Fairview’s gas turbine/generators experienced stator-ground-fault trips attributed to isophase-bus (IPB) water ingression into potential transformer (PT) cabinets, followed by persistent lower-than-expected resistance readings. Doble Engineering was engaged to perform electromagnetic interference (EMI) testing on several components of the plant’s three power trains to assess their condition. Generators, step-up transformers
As usual, a tremendous amount of technical content was offered in two presentations during the HRSG Forum, Jan 28, 2022—No. 7 in a series organized by Chairman Bob Anderson. But the underlying message was more about the state of our industry. A few participants, discussing aging of high-energy piping (HEP), said they were “astonished at
