10 ft fiberglass wind turbine in the Philippines
« on: June 04, 2006, 01:25:35 AM »
Hello everyone, this is my 10 ft fiberglass windturbine in the Philippines. It is based


on Hugh design and has been flying for two years now without any problem. It has 9 coils

and 24 maqnets.



stator and magnet rotor disk assembly





stator and magnet disk assembly with fiberglass cover





10 foot fiberglass blades test assembled in the ground





assembled unit with fiberglass cone installed






assembled wind turbine without tail



4 20 ft section of lattice crank-up tower being painted



tower with work cage and base. Tower is tilted with the base hinge for easy installation. My boy doing his own work too.



Tower completely painted and all sections are installed. Workcage to be installed in the

1st 20 ft section for easy assembly of the wind turbine.





picture of wind turbine installed



picture of the wind turbine 75 ft from the ground with the anemometer in the 62 ft section. The turbine look small up there.





This is my control panel, it has a trace c-40 charge controller, a xantrex 1500 watts

inverter inside. The panel meters are 300v AC meter for our local current, center

meter is 20v DC for battery voltage reading and last meter is a 50 amp DC ammeter.

The black meter is the anemometer.



Sorry for the dark picture. This is the inside of the control panel.





Homemade mechanical winch, use to lift the tower section and turbine.

very nice!

Do you have a steady wind in the Philippines?

Great job I was just in the philippines in april for three weeks and was wondering about wind power there since the wind never stopped blowing the entire time I was on Mindinao. Where are you located in the RP? once again great job and good to hear from someone there!

Nice!   I got a spot of tower envy.

Thank you everyone for your comments. Our average wind speed here in the Philippines is 3 to 7 mph and this turbine generate electricity in the slightest wind. It start at around 5 mph and at 8.2 mph it reads already 11 amps and at 15.5 mph wind it generates 35 amps. I've seen 50 amperes at 20 mph and 62 amperes at 23 mph wind. This reading was taken with my Fluke digital clamp meter since my panel meter reads up to 50 amps DC only. All these readings were taken with a 400 watts load on the inverter.

I am located in Iloilo City, Western Visayas and my place is near the airport. The tower

has a beacon light on top for warning system and this is 12 volts powered.

A really nice machine indeed. Your workmanship

seems to be of really high quality.


Did you make only one set of blades

or more of them for other people

making wind turbines?

Hannu, thanks for the compliments.

I have made a mold for the blades so all would be of the same weight and size, more or less, for good balance.

thanks for the compliments. average windspeed here is 3-7 mph but got good winds

during the northeast moonsoon., this is from the month of November to May, It ranges up to 18 mph.

My idea was that if you did all the work

to make a mold you might make more

blades using that mold to be sold

to other people making similar turbines?


You seem to have made also

a very nice protection case

for the generator. Did you find

a ready made thing for that or

did you cast even that yourself?


Do you know if there are others

in the Philippin making similar

turbines?

Yes Hannu, I could make more blades of this kind with my mold for those who use the same machine.

The cover is fiberglas made too.

So far in our place, this is the first turbine to be installed and lately I have seen one, a chinese made machine flying.

Hi Skyking,


I am really impressed with your engineering work. Your wind turbine looks very professional, just like the commercial ones offered for sale. I have almost the same alternater, 24 Neo magnets 2"x1"x1/2" with 9 coils on dual rotors of 12 inches. However I am living inland in Malaysia and the wind power is rather poor compared to your situation in coastal Iloilo.


My first set of 8 feet diameter blades was too weak to work the alternater and my second set of 11 feet diameter blades are wrongly shaped aerodynamically and much too heavy to spin in my usual low winds of 3 to 6 mph. Yours is serving you beautifully but I am still struggling to get some meaningful power from mine after 7 months on the 53ft tower.


I am especially interest in your 10 foot fiberglass blades. Can you please give more details of your blades? For example:



  1. weight of each blade.
  2. dimensions of chord width, drop and thickness at (a)root, (b)midsection of blade and (c)the tip.
  3. TSR of your blades.
  4. Did you use Hugh's  blade design spreadsheet or Alton's wind calculater for blades in your fiberglass blades.
  5. some photos of your mold to make those beautiful blades and maybe a few tips on making them?


I know the blades are where I have gone wrong as I would be very happy to get some steady power in 3 to 7 mph winds. I can't even achieve that yet. The best I had seen is 3 to 4 amps for a few seconds then its down to less than 1 ampfor a little longer and then none.


Last I am intrigued how you raise your tower by your homemade crank. Can you provide more details.


SeanChan from Malaysia.

Hi SkyKing01,


I'm a graduate student in Materials Science at MIT (originally from Bacolod) and my team recently won in the IDEAS Competition for an innovative project using renewable energy to rehabilitate coral reefs in nearby Sagay Philippines.


Our project, MIT First-Step Coral, uses a method called BioRock that utilizes low-voltage DC currents to electrochemically deposit calcium on metallic meshes. These calcium rich substrates then promote coral growth rates up to 5 times and increase survivability by over 20 times during coral bleaching events.


The electrical needs to power BioRock are on the order of 1kW with 10V or ideally lower voltage in DC mode. Since coral rehabilitation does not have the usage characteristics that humans require, the power does not need to be stored or supplied stably, eliminating the use of battery packs.


With your expertise and REALLY close proximity to the project site, we would like to obtain your help in implementing one of these turbines in the Sagay Coastal area. One of my teammates is already in Bacolod now and would be happy to discuss with you our project further. You can reach me gjlao[at]yahoo[dot]com.


Thanks for your time and I look forward to hearing back from you.


All the Best,

Gerardo, Cambridge MA

Hi Seanchan00,


Its just now that I have open my computer for I was out of town and sorry for my late answer.

Thanks for the compliments, and here are some details of my construction.

Blade weight is 1.20 kilos more or less and a TSR of 6.5. I used Hugh design spreadsheets and you could used it using microsoft excel. Will try to post more pictures of the blade mold and on how the tower is lowered and raised.

The 4 sections of the tower are assembled in the ground attached to the based with a hinge. The base is anchored to the ground with 6,sed. 1" J bolts 30 inches long. A gin pole is then used to tilt the tower using the winch. The tower is so easy to raised and lowered using the homemade winch. The winch is capable of lifting up to 600 kls. Gear ratio is 30:1 and main shaft of winch is 1" carbon steel. I design it myself and I use a commercial come-along winch as a stopper and  release. This has an adapter for electric motor with gear speed of 60:1. It only takes two to three person to work on this tower. One has to crank the winch, me on top of the tower, in the work platform, and the other person to tighten or loosen the turnbuckles. I am using 5/16" steel cables for my guy wires and shackles for easy removal.

Thanks SkyKing01


Looking forward to your pictures so I can have a clearer understanding of your ingenuity esp the tower. If I see your mould I may be able to do the same for myself.


Thanks again for your advice.


SeanChan.

10 years on and I am now living close by Ilolo on an island in Ajuy and am now planning to build something similar in addition to my solar installation and thought I could probably see your installation and talk to you about your experience. But my efforts to spot your mast has been fruitless. Can you please give me some details on how to contact you?

Thanks
