La turbine hydraulique est disposée dans la section de travail (21) entre une extrémité de sortie d'eau du collecteur d'eau tubulaire (4) et une extrémité d'entrée d'eau du tube d'aspiration (6). La turbine hydraulique (1) est raccordée au générateur (31). Selon le générateur hydroélectrique, un collecteur d'eau tubulaire d'un appareil d'accélération à tuyau flottant est utilisé pour former une plus grande différence de pression entre une section avant et une section arrière, la vitesse d'écoulement d'eau est augmentée, le rendement de production d'électricité est amélioré et le générateur hydroélectrique présente une structure compacte.
