Lower Granite Project
Plant size - 810 MW

In February 1995, the ASFM was used to measure the turbine discharge in one bay of the project under three conditions: without fish diversion screens, with standard and extended fish screens in place. A 4% efficiency reduction was indicated for both screen types at low discharge and for standard screens at high discharge, and a 6% reduction for extended screens at high discharge. Back

McNary Project

Plant size - 1060 MW
Publication: presented at WaterPower 1999
(PDF format - 62kb)

In 1998 and 1999, ASFM measurements were compared with Winter-Kennedy index tests, showing consistent results. The results also indicated that the installation of the fish screens in the intake resulted in a 2-3% reduction in turbine efficiency. Back

Bonneville Project
Plant size - 1093 MW
Publication: presented at HydroVision 2000 (PDF format - 426kb)

Use of the ASFM flow measurement technique at Bonneville in 1998, 1999 and 2000, greatly improved the definition and estimation of the effects of fish diversion devices on Kaplan turbine performance. The effect on turbine efficiency of a prototype surface collector (PSC), with and without fish diversion screens in place has been assessed. The results also provided baseline information on the performance of existing turbines for comparison with the performance of new minimum gap runner units that were being installed. The ASFM gave the Corps accurate, reliable data to determine that a 5% loss in efficiency resulted from having the PSC in place. Back

The Dalles Project
Plant size - 1820 MW

The Portland and Walla Walla districts of the US Army Corps of Engineering are engaged in a rehabilitation program at The Dalles Dam on the Columbia River. Turbine efficiency testing is being performed before and after the planned turbine upgrades. As part of the testing program, an initial set of flow measurements using the ASFM were made at Unit 9 in November, 2000. A second set was made after the rehabilitation of the unit in the summer of 2001. Back

Note:

While the first measurement by a particular owner is typically carried out by AQFlow technical personnel, the user-friendly features of the ASFM offer the owners the choice of having the subsequent measurements carried out by AQFlow personnel (indicated above in italics) or by their own personnel (indicated by non-italics).

As shown, Nova Scotia Power, Hydro Québec, Korea Water Resources and Electricité de France have all opted for having their personnel trained by AQFlow technicians as part of the first project, purchasing the ASFM and performing all subsequent measurements in-house successfully and cost-effectively.
