WEIGHT + COST OF MINI HYDRO UNIT
WEIGHT + COST OF MINI HYDRO UNIT
(OP)
Hi all!
can anyone tell me a rough estimation of weight and/or cost for mini hydro power generating unit (turbine + generator) for two schemes:
1) Pelton type unit with 2500KW 50Hz generator, speed 750rpm, pelton runner dia. 0.9m?
2) francis type, with 1500 KW 50Hz generator @ 1500rpm, and with francis runner dia 0.5m
any comparative data for similar plants (or hints how to get them) are appreciated!
Thanks,
Petar

RE: WEIGHT + COST OF MINI HYDRO UNIT
I commissioned a 2.5MW Pelton wheel generator a few years ago. The runner was cast and machined stainless steel about 250kg, the turbine casing, shaft, bearings and injectors I guess would add another 2000kg. The generator was an AVK, 6 pole 1000rpm synchronous machine, which was engineered to withstand full run away speed for 10min. I'm guessing that it must be about 7-8 ton.
My part of the job was to supply the governor and make it all go, so I don't know the cost of the project.
For something of this size would think that $250kUSD will get you the hardware, civil works and installation are a whole separate issue.
Where in the world do you want to install these turbines?
