DIY Wind Turbine Electricity

This DIY Wind Turbine looks like it would have been lots of fun to build. This is just one of the cool creations that Mike Davis has put together. Have a look at his main page only if you have an hour or so of free time to look around. 🙂

 

"I started by Googling for information on home-built wind turbines. There are a lot of them out there in an amazing variety of designs and complexities. All of them had five things in common though:

 

  1. A generator
  2. Blades
  3. A mounting that keeps it turned into the wind
  4. A tower to get it up into the wind
  5. Batteries and an electronic control system

I reduced the project to just five little systems. If attacked one at a time, the project didn’t seem too terribly difficult. I decided to start with the generator. My online research showed that a lot of people were building their own generators. That seemed a bit too complicated, at least for a first effort. Others were using surplus permanent magnet DC motors as generators in their projects. This looked like a simpler way to go.

In operation, the wind turbine is connected to the controller. Lines then run from the controller to the battery. All loads are taken directly from the battery. If the battery voltage drops below 11.9 volts, the controller switches the turbine power to charging the battery. If the battery voltage rises to 14 volts, the controller switches to dumping the turbine power into the dummy load. There are trimpots to adjust the voltage levels at which the controller toggles back and forth between the two states. I chose 11.9V for the discharge point and 14V for the fully charged point based on advice from lots of different web sites on the subject of properly charging lead acid batteries. The sites all recommended slightly different voltages. I sort of averaged them and came up with my numbers. When the battery voltage is between 11.9V and 14V, the system can be switched between either charging or dumping. A pair of push buttons allow me to switch between states anytime, for testing purposes. Normally the system runs automatically. When charging the battery, the yellow LED is lit. When the battery is charged and power is being dumped to the the dummy load, the green LED is lit. This gives me some minimal feedback on what is going on with the system. I also use my multimeter to measure both battery voltage, and turbine output voltage. I will probably eventually add either panel meters, or automotive-style voltage and charge/discharge meters to the system. I’ll do that once I have it in some sort of enclosure. "

    you have done a very good job .but the asseries you have used whether all of them are prepared by yourself in your hose or buyed from the shop or through internet

    hi its very good that we produced the electricity that we consumes.
    good work.
    I have interest in such a type of work.
    plz help me.
    thank u.

    A good introduction about diy wind turbine. You should give a detailed introduction on control and brake system. These are two important parts of a samll wind turbines.
