TIP 413: Kaplan Oil-Less Turbine Testing & Specification Development
Lead Companies
Hydroelectric Design Center (HDC), USACE/PNNL/ BPA
Lead Researcher (s)
- Dan Patla, HDC
- George Brown, BPA
The project develops test stand design for evaluating the durability and effectiveness of the Kaplan Oil-Less bushings and mating materials. Project success enables testing confirmation of: 1. The reliability of the oil less turbine runners, 2. Adequate material pairings to achieve the reliability, 3. Development of specifications that allows future project replacements with Kaplan oil-less turbines.

There is also an increasing emphasis on the requirement for capital investments in equipment and parts replacement to ensure outage times for equipment repair and maintenance are optimized. Return on investment will need to be protected and enhanced in part by program improvements such as refurbishment or replacement of inefficient units with new high efficiency ones; improvements in the design of intake, flow passage, and tailrace hydraulics; and better tools for measuring productivity improvements achieved with planned initiatives. Further ongoing reductions of capital outlay to ensure the continued production of low cost energy will require the development of improved maintenance and repair techniques. Such techniques are seen as using new processes and materials to extend equipment life. These procedures can speed up the repair process to reduce outage times, while condition assessment, equipment diagnosis, and monitoring can optimize “just in time” maintenance.

Lead Researcher (s)
- Gordon Ashby, BPA
The Asset Management Interest Group (AMIG) provides real life examples and direction to implementing Asset Management in hydro-electric utilities. AMIG builds upon work completed by the Asset Management Task Force that was initiated as part of the Hydraulic Plant Life Interest Group in 2011. The group covers all aspects of Asset Management, from the development of policies and strategies, to risk frameworks, asset management plans, and investment management, to achieve strategic objectives. The group considers inputs from all Asset Management standards and the diverse experience of international members to move asset management forward for all members. Topics and projects are user-driven to provide value to members at all stages of the Asset Management journey.

Lead Researcher (s)
- Mark Parrish, HDC
- Gordon Ashby, BPA
The project will develop the Shuffled Complex Evolutionary - Turbine Optimization Model (SCE-TOM) for 5 FCRPS hydropower plants. SCE-TOM will be used in combination with other BPA economic planning tools to determine the feasibility and the most efficient timing for generator rewinds and turbine replacements at these facilities, including the optimal number of units to replace.

Toward Improved Predictions in Ungauged Basins: Exploiting the Power of Machine Learning

Long short‐term memory (LSTM) networks offer unprecedented accuracy for prediction in ungauged basins. We trained and tested several LSTMs on 531 basins from the CAMELS data set using k‐fold validation, so that predictions were made in basins that supplied no training data. The training and test data set included ∼30 years of daily rainfall‐runoff data from catchments in the United States ranging in size from 4 to 2,000 km2 with aridity index from 0.22 to 5.20, and including 12 of the 13 IGPB vegetated land cover classifications. This effectively “ungauged” model was benchmarked over a 15‐year validation period against the Sacramento Soil Moisture Accounting (SAC‐SMA) model and also against the NOAA National Water Model reanalysis. SAC‐SMA was calibrated separately for each basin using 15 years of daily data. The out‐of‐sample LSTM had higher median Nash‐Sutcliffe Efficiencies across the 531 basins (0.69) than either the calibrated SAC‐SMA (0.64) or the National Water Model (0.58). This indicates that there is (typically) sufficient information in available catchment attributes data about similarities and differences between catchment‐level rainfall‐runoff behaviors to provide out‐of‐sample simulations that are generally more accurate than current models under ideal (i.e., calibrated) conditions. We found evidence that adding physical constraints to the LSTM models might improve simulations, which we suggest motivates future research related to physics‐guided machine learning.
