Abstract

The overflowing property of the restricted orifice how to affect volute pressure and the surge level under the condition of large fluctuation and the output swing of the unit under the condition of the hydraulic disturbance were studied. Combining with the engineering features of three adits sharing surge chamber, use general-purpose software to compute for the restricted orifice surge chamber project example. The sensitivity analysis shows that the flowÿstatus of restricted orifice is better while its diameter is 3.5 m and height is 8.25 m, calculation of guaranteed regulation and surge level can also meet the requirements.
