Chip: Pelton not good for 40 feet ( 12 meters) head. The head is low making the Pelton in-efficient With the banki and 20 GPM ( 1.26 liter/second) You need a very careful design for it to work properly. Banki nozzles for this 1.26 liters arrangements plus the need to have a belt to increase the RPM may suffer additional power losses.
With a Turgo, placed vertically, you can attach it to the generator directly that should have very low cogging, like a regular induction motor as a generator. See a photo of what you could have in the site of Joe Hartvigsen http://h-hydro.com, installation that he did on the run (emergency more or less) for his father farm in Utah, it is a 2 KW, I believe, I have not visited the Web site in sometime so I may be wrong. You could get a Turgo from him cut to your needs at a very good price and then you need an induction motor with some capacitors ( I can calculate them for you) to convert the motor into an AC generator ( get one 240 volts) and at the load side you can use a transformer to convert to battery voltage with a good charger as I told you before then you add a simple ( ELC) Electronic Level Controller to limit the voltage when the generator is unloaded. These photos show you a simple way for a Hydro http://www.geocities.com/turgo_gen/turgo_drive.html http://www.geocities.com/turgo_gen/turgoframe.pdf http://www.geocities.com/turgo_gen/splash.pdf Regards Nando ----- Original Message ----- From: "chipbb03254" <[EMAIL PROTECTED]> To: <[email protected]> Sent: Wednesday, March 02, 2005 7:56 AM Subject: [microhydro] Re: Long distance hydro Nando, The best advice I've gotten thus far is from you,, on a different site. The following is what you wrote: { I DO NOT SUGGEST A PELTON, a Vertical Turgo is a possibility. You need a carefull analysis -- 460 to 90 watts (real around 430 to 60 Watts). My suggestion is a high voltage generator, 240 Volts AC like a 1.5 HP induction motor as a generator, or a PM 3 phase brushless Smart Drive motor from Fisher & Paykel with two set ups, DELTA for high power and STAR for low power and transformers at the load to bring the voltage to the charger ( I suggest a C40) } You suggested a BANKI at one point. Whats the difference between it and a Vertical Turgo;;; I gather a pelton is not practical for this application.
