Hello, A simple google search should turn up some companies and units you can purchase. You'll probably want an Aussie supplier like http://www.planetarypower.com.au/ or http://www.rpc.com.au/. A turgo or pelton turbine sounds like the go for your site but I'm not sure about switching systems.
Keep in mind that if you want 4kW electrical output, and assuming an overall system efficiency of 60% then you'll need approx. 21 l/s of water running through it for a head of 33m. So, there may not be much 'switching on' during summer, only 1/21th of the time based on your 1 l/s figure (one hour per day as a rough calculation). You may think of a slightly smaller unit (might be a bit cheaper) that runs continuously during the winter months based on your 15 l/s figure and then the switching kicks in if you get a flow rate lower than this figure. The electrical output would then be more like: 15x33x9.8x0.6=2.9kW, but you'll need to check the system efficiencies, heads and flow rates of the products on the market. regards Robert Simpson -----Original Message----- From: [email protected] [mailto:[EMAIL PROTECTED] Behalf Of vvvffernhurstsuzi Sent: 19 June 2005 03:37 To: [email protected] Subject: [microhydro] New installation of a micro hydro generator 4 KW Hello all, I am a new member, my background is in electrical engineering. I have recently purchased a rural property in the High country of North East Victoria, Australia. There is no power on the property. The property has a spring fed dam which in summer months, water flows at about 1 litre per second and in winter months at 15 litres per second. From the spring fed dam to the lower part of the property which is located about 150 meters away the head is 33 meters. I'm looking at installing piping from the spring fed dam to a hydro generator of approx 4 Kw, 3 phase power 415Volt, 50 Hz. I will use automation to switch the generator off and on depending of the water level of the dam. The electrical power generated will be rectified to DC to charge batteries and then inverters used to convert to household power for continual use. The excess electrical energy will be used to pump water to higher levels of the property. I can take care of the batteries, chargers, inverters and pump but I need some assistance on selecting a hydro generator that can be switched on and off regularly and piping installation. Can someone recommend a suitable system that I can purchase Regards John Rainone Does your company feature in the microhydro business directory at http://microhydropower.net/directory ?
