Maintenance Costs: High. The first option was to repair the old ASEA UAAF 170 unit by installing new internal components, new bearings, and an upgraded lubrication system. Johnson offered one example from a project he was involved in at the Grand Coulee Dam (shown in the opening photo). The REguard face seal with integrated PIMS (pressurized interface management system), shown here, includes thermocouples (top left), wear-down sensors (top center), and interface injection ports (top right). Orwick said that modernization programs could be driven by a wide variety of factors, including relicensing requirements, changes in plant usage, environmental mitigation efforts, a desire to increase capacity, and reliability or availability concerns.

Another question that often arises is: “If a unit is being taken out of service for an extended period of time to complete one plant improvement, does it make economic sense to increase the scope and take care of other upgrades at the same time?”. “One of the biggest advances in governor technology over the last 10 to 20 years has not been in functionality but in the type of equipment that’s been used,” said Roberts. The mathematical models developed earlier for operation of hydro power and techniques to minimize the operation cost as well as maximization of energy generation of hydro power plant have also been presented for the benefit of the researchers. Courtesy: Voith Hydro. A market report released last year by the U.S. Department of Energy Wind and Waterpower Technologies Office noted that of the 2,198 active hydro plants in … “So it’s really a communication tool as much as anything else.”. For them, showing up onsite with a full parts kit, doing a top-to-bottom governor disassembly and inspection, replacing worn components along the way, and recalibrating the reassembled governor is just another day on the job. You can send alarms back and say ‘this specific thing failed.’ You can change the operation.”. Roberts said there are just certain things that are quite a bit harder to do with a mechanical governor than with a digital system. The technology used in most seals is not new, but in the past it has been hard to predict when wear components in the seal were approaching their end of life. His group was brought in to evaluate the step-up transformers (Figure 2) for a couple of the older powerhouses. With a total installed capacity of 6,809 MW, Grand Coulee has enough spare transformers (and generation, as it rarely runs at full capacity) to weather a transformer failure. It had been repaired several times by third-party gearbox service companies, but it continued to be plagued by high operating temperatures, and some cracks had formed on internal components. Smooth operator. Creak suggested that the combined solution could significantly extend maintenance cycles.
