Machine Condition Monitoring
• How do we keep the existing fleet reliable? • Use of Data Analytics
• What devices do we need to develop? • Those plants that cannot afford to put these systems in • Impacts of Operations
• Late 1995 DOE project on Machine Monitoring • Identified Devices – Integration was a challenge • Vendor evolution has continued, but these system view the world from the
specific device perspective • i.e. if high vibration, what are bearing issues?

Starts and Stops
• What are the impacts of frequent Starting and Stopping? • Monitoring Systems? • Horizontal Machines / Vertical Machines? • Pump/Generator Units ?
• Effects of Rapid Start? • What does it cost? • Is there a cyclic life on components?
• i.e. after 20,000 strokes of wicket gates you need to re-bush? Re-bore servo?

Dam Safety Is there a way to “look” under the concrete at depth?

Dam Safety Can I use GPS, or other system to measure deflection of arch structure with seasonal temperature changes?

What can we Borrow from Wind? • Solid Core Stator? • Inverter technology • Gear technology? • More packaged integration of electrical elements?
![Page 11: Technology Advancement for Hydropower Industry …...Technology Advancement for Hydropower Industry Needs Perspective Presented to US Dept. of Energy 2017 Executive Summit Hydropower](https://reader033.vdocuments.us/reader033/viewer/2022050113/5f4ab5f28f313d2c5b531bb0/html5/thumbnails/11.jpg)
What can we do to reduce Construction expense?
• Concrete that doesn’t require re-bar? • Printed concrete turbine water passage?
• Provide modular assembly? • More cost effective shipping?
• Standard Environmental Mitigation Methods? • Develop models for mitigation rather than field tests? • TDG Models?

Distributed Control Methods?
• Using Small Hydro on electric distribution feeders • Opportunities to reduce demand, improve feeder function
• Controls to aggregate sources to provide services to grid • Must do calculations nearly instantaneously
• Locational benefits of smaller hydro for utility • This is same type of research as DER, but very different size and geography

Impacts of Future Grid Changes
• Effects of Distributed Resources on traditional resource operation • If DER’s do become prevalent, at what levels might it change the operation of
conventional resources? • What would the operation look like? What would flexibility look like there?
Would more storage be needed? • Effects on present electric distribution feeders? Opportunities?
• Assess impacts of adding more storage • Drought concerns • Grid support concerns
