Optimizing Joint Load Control for Hydroelectric Plants

by Durl Jones, Woodward Governor Co, United States,



Document Type: Proceeding Paper

Part of: Waterpower '89

Abstract:

This paper discusses a method to minimize water usage at a multi-turbine hydroelectric generating plant. At plants which do not spill water this optimization is directly converted to extra revenue. Conventional Joint Control Systems share the station generation at its set point. For the optimizing approach, a digital controller is used as a joint generation control of a multiple-turbine hydro station. The individual generation levels are adjusted to minimize total water flow at any given station generation level. This process is based upon individual turbine power vs flow data which is obtained from index testing.
