| Abstract: | The ventilation of a Bulb Tubular Turbine Generator (5 500 kW/6 471 kVA) had been calculated using the finite element method. The distributions of pressure and velocity of the ventilation were obtained. The different configuration of hydroelectric generator can generate different pressure field of the ventilation. The modification of the configuration on which there exists a high pressure drop is a help to a reasonable design of ventilation. |
