Your overflow pipes are to large is what is happening
@retrofitter 14 күн бұрын
If you put the rectifier at the power house you can reduce the power loss in the cable. If I understand correctly the rectifier only draws current from 2 phases at any one time. If you send DC over the cable you can use all 3 conductors at the same time. This will help with the minimum input voltage if the inverter. Further more if you put a filter capacitor across the line at the powerhouse it will boost the voltage higher again. Don't do this if you are near the rated current output of the turbine though as it generates more heat in the coils.

At the 11:30 min point you say the water is going under/around the wooden dam. I would have put a short length of pipe there with a bung on the lower end. This will keep the dam dry and allow you to seal it better, also you will be able to drain the lake to work on the dam in the future, also you can drain out the sediment form the lake if necessary.

Totally. I should have done a little more research into how to build a small dam but I just went for it! I think next time I need to do any big maintenance on the thing I will for sure add in a pipe underneath for all those reasons - thanks!

Overflow should shoot water farther from the dam, dropping it so close risks eroding at the base. Keep at it, I’ve got a system that’s been going since 2008 myself. Only one 5/16” nozzle at 58psi around 400watts. Fed with a 2” pipe. I feel like you should be getting more than 500watts with 140psi and a pipe that size.

I think a great addition to your dam would have been a 6" Drain at the bottom. like under the dam have a pipe bypassing everything with a 90 pointing up. Then you add a pipe to the 90 the is not glued that controls the water level. then when you want to drain the dam you just yank the pipe out and the water level will stay low to a bottom mounted drain allowing silt to be removed and maintained. If you need a picture, I could draw you one, but this is how full sized dams do it. it might be called a "Glory Hole"

So other than working on the flow, I wonder if there is any other optimization with what you have. What's the potential power of the water (height and flow rate)?

I agree with you, while you have low water flow, change the first nozzle size so it runs consistently on 1 nozzle while still maintaining some water overflow. In a few months when the water flow increases fit the second nozzle with the biggest size that produces the most power yet still maintains some water overflow. Ideally you might want to fit a third nozzle. The first one sized small-for low water flow. The second nozzle should be sized to increase the power output from the first nozzle, only when water is available. The third one sized large-for high water flow.

You really shouldn't run your turbine without any load on it and full flow; you will likely exceed its maximum rated speed. I suggest designing some kind of pit or sump in which the turbine housing sits. That way, you are likely to catch any water coming from leaks on top of the turbine discharge.

Yes, I only ran it unloaded as the guy who helped me design the system wanted to know the output to help for the specs for programming the inverter. Now there is always a load on it.

9:46 you opened your valve pretty quickly! You have about half of your barrel flowing down your penstock all at once and more water flowing in. That means about a hundred litres of water rushing down your penstock to your powerhouse. I don't know what is the height difference, but you basically have a 100 kg battering ram of water going downhill. It might cause a significant pressure spike and some serious damage!

Good call - I actually filmed the pressure gauge in the powerhouse once while I turned the water on at the barrel to see what it did. I didn't see any spike in the pressure when I watched the video but I think the penstock is so long (900m/3000ft) there is pretty significant friction as it flows down. Thanks for the concern though, I certainly don't think of them all! Cheers

Question, but when the batteries are charged what keeps the turbine slowed down? The turbine would find itself without an electrical load, it would spin freely at very high speed, generating high voltages and stressing the bearings unnecessarily, this thing is fine for a few minutes to make a video like the previous ones, in the long run it would break down, and it is not the correct way to work , there are two solutions or a constant electrical load derivation, perhaps using a small reliable electric heater without fans for heating, which is the best solution given that it also protects the downstream electronics or shuts off the water when the batteries are full .

I just installed a similar hydro in Nicaragua for my sister’s family, some suggestions for you to consider. The inverter/charge controller you are using has a minimum MPPT of 120V. (Depending on which windings your hydro PMA has) your max power could be a lower voltage than that, watching the video. I see it stays at 120V which makes me think it would find more power at a lower voltage. One simple way to check this out is to check your Voltage at free spin with no load connected, between 1/3 to 1/2 of that voltage is your max power. Hopefully, you can get the thing working again and figure your freezing problems out! Looking forward to seeing more of your video updates.

Thanks for your response! Yes I'm not very well versed on the inner workings of my inverter. It's been off all winter but hopefully I'll be able to fire it up again soon! My highest unloaded free spin output was 214 VDC. You're thinking if I can lower the voltage of the MPPT my wattage would continue to rise? Did I follow that right?
@travisroyer7113 5 ай бұрын
Yes sir, your free spin voltage is going to be directly related to whatever your psi is while the Hydro is running. So if you put bigger nozzles on, (which I suspect would get you more potential watts) your working PSI will drop, then your free spin and max power point voltage will get even lower. For example, I used a midnite classic 250 on my project and it is finding the Max Power Point around 205V which if I remember correctly is around 43% of free spin 475V. so in your case if free spin is 214V 43% of that would be 92V. That alone would probably get you an extra 150W with your current nozzles. but remember, if you put bigger nozzles on your potential watts will be greater, but the Max power point will be even further away (with the inverter/charge controller having a minimum of 120V MPPT) So it’s likely you will not see any power increase. (if my assumptions are correct) hopefully this makes sense.
