Generator Users Group

James Joyce, operations manager, MD&A’s Generator Repairs Div, speaking at the 2022 conference of the 7F Users Group, May 23-27, in the Fairmont Dallas Hotel, focused on three topics of particular importance to owner/operators of 7FH2 generators: Spring migration, collector changeout, and flex-link systems. All styles of 7FH2s—Gens One, Two, and Three, plus 324s—are affected […]

Jamie Clark of AGT Services kicked off the vendor presentations at the 2022 conference of the 7F Users Group, May 23-27, at the Fairmont Dallas Hotel, by addressing stator-core looseness in generators for gas- and steam turbines. Perhaps to jolt the audience awake after breakfast, Clark noted that there’s a “huge uptick” in stator-related problems”

There are nearly as many electric generators at fossil-fired and nuclear powerplants as there are gas and steam turbines combined. So, you might think that with thousands of utility/large industrial-grade generators rated more than 25 MW operating in the US alone, the annual meeting of the Generator Users Group (GUG) would draw hundreds of attendees.

Commissioning seven gas-turbine (GT) control systems in seven weeks would probably be taxing under the best of conditions. In NV Energy’s case, there were some extenuating circumstances. First, the seven systems are located at two generating facilities acquired by the utility in 2014. Second, it is challenging to test a retrofit, due to air permit

CCJ ONsite’s coverage of technical highlights from the Generator Users Group’s Third Annual Conference, held in Phoenix, Aug 27-30, 2017, concludes below with the third and final installment of lessons learned and best practices shared among attendees. Presentations and discussions are arranged in these five sections: Stator frames and magnetic cores. Stator windings and bus systems.

Generation assets in competitive markets must perform at a high level year in and year out to meet their contractual obligations. Failure to embrace a philosophy of “continual improvement” in plant operations means it’s only a matter of time before the competition will eat your lunch. The focal point of continual-improvement efforts typically is the

Paul Tucker called CCJ’s editorial offices a few weeks back with a generator experience to share with users. Say Whaaat? Tucker is well known to engineers and technicians at power and process plants for his ability to identify the root causes of turbine problems. There isn’t much he hasn’t experienced in his 50 or so

You don’t hear much at industry meetings these days about physical security of power generation and delivery infrastructure and personnel. Cybersecurity topics get most of the attention. But that doesn’t mean work on physical security solutions has stopped. Certainly not. One recent development concerns transformer protection. Six years ago (Apr 16, 2013), you may recall,

There are numerous instrumentation systems used in attempts to assess the condition of powerplant electrical equipment. The library of papers about them is vast. But papers discussing detection of failing electrical connections inside generators or bus systems are limited in number, Consultants Clyde V Maughan and James E Timperley told the editors. The focus of
