Off Grid 2 KW Axial Flux Wind Turbine And MPPT Dump Load Controler Build

[@KrisHarbour]

The idea for the controller came from another KZbin channel. The clip I had crediting the channel had bad sound and got cut out. But visit wind power and more to see other versions of this controller and some great content. kzbin.info/door/pHl5wAaAYKhWvkDHaRXjlA

Make a set of blades man you can make them lightweight out of stainless steel, and instead of having the excess go into the dump wasted, can't you have like a fridge freezer instead ie fridge freezer gets powered by ordinary set up then once ordinary set up cuts out due to overpowering and switched to dump can't the power going into the dump power the fridge instead until things go back to normal so nothing is being wasted etc ? Man if that was me I'd experiment so much I'd probably blow the lot etc I Just can't stop but it's the only way you learn but anyway back to the fridge being powered by the dump after it takes over seems good no? And get those blades made man seriously for the wind turbine I know you can make a banging set of blades ? Try 5 ? Smaller but just as potent etc then the pole won't be taking as much flack, anyway brilliant job and I tell you what once I go electric VERY SOON you'll be making my stator and turbine and blades AND fitting it all too seriously your only A 2 to 3 hour drive from me so all good I'll give you the sizes they have to be and you work your magic with NO TIME RESTRAINT at all plus I'll pay you up front if need be 50/50 anyway apart from my rant good job brilliant stuff and I hope we meet one day so I can have a go at you about something the only thing your good with ? so take care of em mate seriously I know we're not fairies but mate ? take care of em as YOU DO everything else ok 🤗

[@paperburn]

The only real thing I would do different is the tower, I would hing it in the middle so raising and lowering would be easier. Just have to wire it with that in mind. weight reduction of the head would be great but who wants to drill one million holes for such a minor improvement of low wind speed power performance, Great job overall and it should last decades.

Hey Kris, I am super impressed and motivated by this video. Thank you so much. One thing that disturbs me is armchair engineers who comment with a better way to do something when they are unable to produce a video of their own to prove their point. That said, I have to tell you that your technique for raising of the Turbine could use some improvement. I helped a friend build a tower for a commercial wind turbine in 1999. The tower was 60' in height, constructed of 2" SCH40 black pipe and held in place with 6 guy wires connected to earth anchors. We used a simple "Gin Pole" design and it worked excellent with very little effort. I will post a link in a separate comment so YT wont censor it. Again, thank your for the video, Blessings my friend.

Hi Chris, 32:20 the reason why the blades are tilted back at a 5 degree angle is because on bigger wind turbines blades flex and would end up smashing against the main upright pillar and destroy itself.

[@lemagreengreen]

What a project! love the longer videos. I always thought an interesting/useful dump load in the UK climate would be a buried, insulated tank of water that is used to heat a greenhouse through radiant underfloor heating pipes. I've never sat down and done the sums on it but the idea has always been with me... especially as temperatures dip and I wonder what could be grown in a heated greenhouse in winter.

[@kalimgold9268]

check out some vlogs of all year round greenhouses in the north usa, they use big pipes buried circulating the air, sunken like gruber huts, citrus trees etc. grown in them, the north side is usually a bank of soil

I too like dumpload idea, and underground water tank I know a scientist that has a very large tank that he just paints black lol. The problem with wind were i live is many nights there is very little wind. I would be tempted to heat with solar and use wind to run half the waterpumps.

[@stevewoodw]

About the twists in the cables - either a chain (to stop excessive twisting) or a spring which returns the turbine to it's starting position might be worth considering (similar to springs on gates to close them). This may take a while to source but could solve the problem. If you don't sort this and the cables are going to be stretched, although this doesn't happen very often, having them as a standard serviceable part that you can unplug and replace might be worth thinking about for future designs.

[@ferrumignis]

Trouble with this is you could end up throwing power away when the wind turbine is prevented from fully turning into the wind, and this situation could last a significant length of time until it resolves. Also it could prevent the turbine from furling in strong winds which could be catastrophic. Just another unfortunate trade-off in a system with no slip rings.

48:56 You could make some electric heating elements your dump load and then make yourself a huge sand/thermal battery... You've got the space for it and it should be relatively cheap to make. Install a few electric heating elements in some tubes inside a much larger container, install a few more tube for air flow or liquid flow, make sure it's all sealed and insulated, then just fill it with a few hundred bags of sand. The waste electricity would be stored as heat, thanks to the sand, and if you needed some heat, especially in the colder months, you could just pull the heat from your sand battery to heat your house and/or workshop. I'm not sure what heating method you use currently, but whether it's wood or gas/propane, you'd save on fuel even if you only boost the temp by 5° with your sand battery. At least that way you'd be making some use out of the waste electricity and you won't have worry about overloading anything as much.

Very nice work! Another tip, if you make the coils slightly trapezoidal you can pack more copper in the windings. Only the radial sections of the wires generate electricity as they pass through the magnetic field.

[@nicolasuribestanko]

@ahaveland...... The last sentence of your comment left me puzzled. The cross product of the magnetic field vector and the motion vector yields a current in the direction of the windings.... or maybe I didn't understand your comment. It's as if you were saying that the wire on the 2 long sides of the windings is being wasted.

[@ahaveland]

@@nicolasuribestanko no, the wire on the short sides is mostly wasted as there they are mostly outside of the magnetic field, and there the magnets move along the wire, not across them. This is why long motors are more efficient and have more torque than short ones because there are more and longer windings inside the fields than out of it. (edited)

[@nigelwilliams7920]

Great work and thank you for taking the time to tell us about your efforts. While unbridled wind power generated by a free-spinning turbine is great, and just does fine, I offer the following thoughts for your consideration, noting that you have a PWM output from your controller... A HAWT works most efficiently with a tip to wind speed ratio of about seven. i.e, the tip is moving at seven times the wind speed. (tip wind ratio = 7 TWR7) Below and above that TWR the turbine doesn't extract as much energy as it could. Often (usually, I suspect) the turbine is working in a near stalled state, where the drag of the generator is holding the rpm well below optimum. This will have the undesirable effect of slowing the run up of the turbine to optimum rpm as wind speed increases, which means you are not maximising the energy harvest. In typical cyclic wind conditions I think it will be better to grab shorter bits of charge at closer to optimum rpm than having the turbine spin at near stall a lot of the time, when it is not generating much at all, but it cannot (because of the load) get up to speed. So to optimise output, it would be good to allow the turbine to spin up to the TWR that approaches seven times the prevailing wind speed before you start to pull load off the generator. So; rpm counter on the turbine will give you tip speed, and a basic wind speed meter mounted on the pole will give you wind speed. Then, via trivial software and math (using an Arduino, say) you can compare the two speeds and get a PWM output proportional to the speed ratios which you can apply to your poor overworked solid state relay to send the load to the batteries. (A capacitor downstream of the relay may smooth the output a bit, and it will be interesting to see if the PWM rate needs to be controlled a bit to avoid excessive cogging and thus cyclic loading of the turbine as the load is varied. Later) I believe this method of control will have the effect of letting the turbine run faster and hence it will grab more of the passing wind energy since it is working closer to optimum. Thinking of it starting from slow spin in low wind, the wind increases, the TWR controller allows the turbine to spin freely up to your desirable TWR then starts pulling power. As wind speed steadies, the turbine is kept in the sweet spot. As wind slows, then the controller promptly proportionally unloads the turbine allowing the flywheel effect to have it spinning faster in anticipation of the next gust. So overall the turbine will operate for more time closer to the optimum TWR. Practical considerations (like the probability of the rpm exceeding the structural integrity of the blades, bearings etc) may see you choosing a lower ratio (like six or five) but anything approaching the ideal seven will be of use, compared with running the blade far out of the ideal range in a near stalled state most of the time. Good to keep tip speed below speed of sound. A turbine with blades 1 m long (2 m dia) has a tip path circumference of 6.3 m, so to get that spinning with tips at the speed of sound requires 55 hz or 3275 rpm. That would be in a wind of 49 m/s (176 km/h). Hopefully your feathering mechanism will have cut in before then! FYI I'm in the process of making a small turbine setup to test this myself and will report when / if I reach finality on that work. Hope this is of interest to you.

My wife and I, from Oklahoma, USA, love to watch your videos.

[@TheTubeTube2]

Really did enjoy this long episode Kris (kind thoughts to Dot), so interesting to see you making the winds and constructing the wind turbine. Great stuff. I do agree with your concern about the tube at the top of the pole being a likely fracture point - but a stout bit of sleeving should do the trick. All great stuff! And building to look forward to as well !

[@jasontoflinski]

Longer the video the better, your channel is truly one of a kind. Thanks for sharing your life, creations, and innovations with us.

Great stuff as always Kris! I had always envisioned a dump load on a wind turbine as a heat and/or water heating element and use it to heat a body of water within my green house, which will then slowly be radiated out to prevent frost. I bet your workshop will warm up nicely from on ocassion.

2 minutes in I realized this is a 1 hour video, holy smokes! I wish you had more time and energy to post longer videos like this one. You're awesome.

Another awesome and well presented video,,your engineering prowess just blows me away. Love how far you've come from sandbagging to a beautiful off grid homestead.

Hi Kriss. I just wanted to give you an idea of an option for your excess energy. You could divert any excess through an immersion heater for hot water. If you have a large enough tank, you could split the water via a smaller tank and pump that through a radiators either in the workshops, or the house. It won't necessarily create the amount of hot water that a on grid system would give you, but it's somewhere to divert your excess power once your batteries are at full charge. A simple controller would create a system that would work. Anyway, I'm enjoying your videos immensely. Keep on doing what you do best.

Impressive skills! Always look forward to your vlogs.

[@MATHEWROSS-n9o]

New to your channel and am absolutely fascinated by what you do! I noted during one of your water wheel hydro videos that you said that you can't do the electricals at the house because you're not certified. After watching this video, I challenge any of the certified electricians out there to achieve what you do! Wonderful channel and wonderful videos!

[@djrrmml7514]

You could use a voltage sensing relay to trigger aux 1 if for some reason the voltage on the turbine gets to high due to the a malfunction of the ssr as you mentioned. Sad to see less energy projects in the future, however I'm always pleased to see your other videos as well:)

[@Teknopottu]

It seems SSR:s usually fail in ON position so less worries.

[@michaelwellendorf1993]

I'm very impressed of your skills. Lots of inspiration for me! 🙂 I'm also using a dump load approach - but for a solar-thermal system. In my case this is a 4.5kW radiator, which consumes any heat I can't store. Since I installed that, the wear on my system significantly decreased.

just a heads up for the sake of skin cancer; welding makes insane amounts of UV radiation and it's a good idea to use gloves / longsleeves to help reduce accumulated radiation damage -- Love your videos so far!

[@M1splace2day]

Loved the video! It's the 1st of your videos I've watched and found it to be quite inspiring. I think I'm going to pursue some more DIY projects myself because of it. I can't help but feel more and more these days like our time in the world today having all these luxuries and conveniences is limited and will soon come to an end leaving all of is who arent prepared doomed to an unpleasant demise. Being prepared and having the ability to survive on my own is becoming a top priority and having people like you around to help me establish a plan is priceless. Thank you for taking the time to share this information.

[@jimjones2256]

Honestly dude I have no idea what anything you said means, but I really did enjoy watching your skill and ambition to live off grid. Thanks!

[@randymch]

Great video Kris. It literally makes me physically sick how difficult it is for average Joe Public to put up a usable wind turbine in this country. Planning permission... Lack of companies who offer turbines... and lack of small scale (domestic) wind energy expertise. Love seeing this kind of thing.

[@danutztihu5802]

it's as if someone would want to intentionally stifle the development of green energy.

there is no money for them, they need to sell you electicity and fuel at the price they enjoy massive bonuses, just check top managers' bonuses at energy companies
