Abstract

An index test was performed September 30 and October 1, 1987, on Unit #1 of Prospect Powerhouse #2, located near the town of Prospect, Oregon. The testing was requested by the American Hydro Corporation and was scheduled to be in conjunction with a possible runner upgrade of the facility. The facility owner is Pacific Power of Portland, Oregon. The primary personnel involved were: Mr. W. Colwill, of American Hydro Corporation; Messr's T. O'Conner and R. Landolt of Pacific Power; Mr. R. Voigt, Jr., of St. Anthony Falls Hydraulic Laboratory, University of Minnesota. Numerous Pac.1f1c Power maintenance and operational personnel were also involved. The purpose of an index tes,t is to determine the relative unit efficiency at various wicket gate positions. Through this type of testing the most efficient wicket gate position can be verified. This is typically determined by varying the wicket gate position from either full gate to closed gate or vice versa, in a series of small, usually 5 to 10%, increments. At each position, approximately 15 to 20 parameters are measured. Some of these parameters such as generator output and·relative flow measurement are used in the computation of the relative efficiency values, while others may affect turbine efficiency either directly or indirectly.
