BULB - TYPE GENERATORS FOR ST. MARY’S RIVER REDEVELOPMENT PROJECT

Pages 243-259 | Published online: 23 Jan 2013
 

Abstract

Bulb - type hydro generator’ installations are a relatively new development in North America. Compromises must be made in the design of the generator in order to obtain the best overall complete unit. This paper reviews the design philosophy used for the three 18.2 MVA bulb-type generators for the St. Mary’s project and describes the components of these generators. Comparisons are made between the bulb-type generator and the more conventional vertical hydro generator.

L’installation de generatrices à bulbe est relativement nouvelle en Amérique du Nord. Il faut faire certains compromis lors de la conception de la génératrice en vue d’obtenir les meilleures caractéristiques générales pour l’ensemble de l’appareil. Cette communication présente les parti-pris de conception utilisée pour les 3 génératrices à bulbes de 18.2 MVA qui sont installées dans le projet de Sault-Ste-Marie, et décrit les composantes de ces génératrices. On compare la génératrice à bulbe avec la génératrice verticale conventionnelle.
