Advantages of this solution are:
1. Power Potential. The TGC arrangement will meet the 1,000 kW maximum requirement but has the
potential for increased output if permits are in place. This would be readily accomplished via control
modifications.
Civil Modifications. The TGC arrangement, as proposed, will require minimal civil modifications. The bulb
turbine unit is an easy, compact solution that will fit within the existing structure. The intake is designed
to provide a smooth transition into the turbine. The draft tube will require change in order to assure
performance of the unit and provide a straight flow path.
|
Fish Passage. The MAVEL KA1800K4 turbine with four blades and operating at 240 rpm speed will
minimize the potential for impact on fish passage through the turbine. There will be no impact to the
upstream fish passage facility.
