Hydraulic Performance Optimization of Bidirectional Tidal Power Turbine

This paper analyzed the relation between tidal level and reservoir area water-head of Jiangxia experimental tidal power plant,which is a bidirectional station with a reservoir,and then concludes the change pattern of the tidal level and operating parameters.Through 3-D numerical simulation,the hydraulic characteristics of the bidirectional bulb turbine under multiple operating conditions are analyzed.And based on this optimization design of a new bidirectional bulb turbine with the fixed flow passage size,including parameter (diameter ratio of runner to bulb,guide vane angle and guide vane/runner blade shape) redesign,is conducted. Key achievement of model units after model acceptance test is also available.The new type unit in Jiangxia tidal power plant,unit #6,in which the research outcome has been directly utilized, achieved stable operating for both forward and reversed generation,pumping and draw-off. Moreover,comparing with other units equipped,there is an over 6% efficiency increase for both forward and reversed generation.Besides,turbine general performance has also been dramatically improved.
