Abstract
Salient features of the powerhouse design include selection of an indoor-type powerhouse and elimination of a generator floor; implementation of a control philosophy stating that the control room should only be provided with the control elements which would be provided at a remote control station and a basic requirement that control functions and equipment should be flexible as regards modification to suit future operating requirements; installation of a digital operations controller which is intended to lead to future closed-loop control of the plant; grouping of four large hydro units on each 500-kV transformer bank; and standardization of the design to include Lower Monumental and Little Goose Projects to effect savings in design and equipment procurement costs.
