Hello to the group- I would like to increase the power close to the max gen rating.-if possible! Here is the situation the turbine is designed for 30,5m head and 500l/sec flow( 125 kw). , it is mounted on the generator shaft that is rated 200 kw at 900 rpm. I have a site that has way more flow and I could use more head
Option 1 - -can I install a runner that will take more water,but stiil fit into the spiral case without any modifications and turn at the same rate.Will not the turbine and shaft be overstressed?? Option 2-make another twin (copy) turbine and join the shafts by clutch-that will also increase the rpm option 3-increase the head -some books say that it could be done up to 25% of the design head-what about increased rpm(will the generator and electrical controls and panels take it?) ,cavitation and stresses on the turbine and shaft?? Option 4- the easiest and cheapest way is to make a copy the turbine , controls and panels, get another generator and install them both as 2 identical units .
