Now includes 10K Supplement........twice the power!!! These are the largest homebuilt wind turbines in the World!!!! Breezy 5.5 A Reliable 5500 Watt Homebuilt Wind Turbine Generator By Timothy D. McCall and Alan E. Plunkett A how-to book/plans!
Build your own 5500 watt or 10000 watt wind turbine generator.
This is a REAL turbine. When in operation it will begin cycling and producing power in a 8 mph (ground speed) and ramp up to 5.5kw at 23mph. In a zone 3 wind power area a Breezy 5.5 turbine will deliver an average 1000kw (1megawatt) per month to the grid or for your use. This turbine will rival a particular 10KW commercial built turbine costing 40,000 dollars and up to have installed. The details provided in the book will allow anyone with reasonable welding, woodworking, and wiring skills to build with ease. We have worked on this wind turbine design for 5 years and made 11 blade design modifications. We have a blade/rotor design that starts at low speed, reaches maximum output quickly, and has taken as much as 70mph wind gust not missing a beat.

The theory behind induction grid-tied generation: Breezy 5.5 is out there generating power (providing the wind is blowing at least 8 mph) at the rate of 2.1 to 5.5 kW per hour (see note below). Your family is using power at varying amounts during the day and night. When you are at work, asleep, or just running the TV, a few lights, clocks etc, Breezy is providing power for your home and pushing excess power through your meter and building credit on your electric bill. Let's say mother is baking a cake, Breezy can't carry the load of the range on its own so you'll need extra power during that time and that will take some of your built up credit away. Its Breezy's relentless day in day out push of power onto the grid that will provide credit on your meter. How much power? Up to 5500watt = 23 AMPS at 240 VOLT 60 hz (at 23mph wind)!!! That's enough to power the average home air conditioner, 18 amp 240 volt, and have about 30% left over for credit back to the power company or to power other things. A turbine generator, built with locally obtainable parts, not specific to wind turbines except for our controller. . How is a direct grid-tied turbine different from other grid-tied turbines? A direct grid-tied turbine has an induction generator (motor) connected directly to the grid (your house and it's circuits are connected to the grid) through a relay which is controlled by a micro-controller. A turbine which is indirectly connected to the grid produces power which is not compatible with the grid power (or your house circuits for that matter) and must have an inverter to change the power into 60 HZ AC that is then connected to the grid. Problem is these inverters must be "sine wave" inverters instead of the cheaper "modified sine-wave" inverters and one large enough to handle a turbine as large as Breezy 5.5 often times cost as much as the turbine itself.

Where else you can purchase plans for a grid connected turbine that includes 24/7 access via phone and e-mail support from the guys that designed the turbine? Which other plans include troubleshooting help if you aren't able to get it to work? Which other plans include updates and notices available on their website? If you are serious about building a turbine you'll find our book/plans worth every penny. Youtube videos of the turbine: goto www.youtube.com search Breezy 5.5 If you were to purchase grid tied wind turbine generator the size of Breezy 5.5 you’d be spending $30,000 to 40,000 with a payback of well....never. Just not very practical for the average working man. You can build the Breezy 5.5 yourself with our plans and locally obtainable parts and you’d be spending $3,500 to $4,500 (we built 2 of them for around $3,500 ea.). That’s not a bad payback at all. The average daily wind speed in Kansas at 60’ is 15 mph and most large wind turbines including 20 kW machines have an output of around 3.6kw at that speed. Breezy 5.5 is right there with the big shots at wind speeds of 15 mph. In fact Breezy 5.5 beats most wind turbines including those large 20kw machines at wind speeds below 15 mph with a near linear output to 5.5 kW at 23-25 mph wind speed. How can it be that Breezy 5.5 can out perform those lager turbines at lower wind speeds? It’s those 4 large wooden blades. They have a tremendous amount of lift at lower wind speeds and an equal amount of drag at higher wind speeds to limit the power. We’ve designed Breezy 5.5 to operate within the range of the bulk of our wind speeds between 8 and 25 mph. And, since the drag is offsetting the lift created by increased wind speed above 25mph there is no need for any pitch controls at all, eliminating failures that plague wind turbines with these kinds of controls. When you build the turbine using the plans in the book you will be building a turbine just like the one in the picture below. It will be mounted on a 6-inch tilt-up tower 60 feet in the air. Weighing in at nearly 1000lbs, Breezy 5.5 is no lightweight. You will not want to cut corners on the mounting structure or material sizes in any way, been there, done that. The plans will show you how to measure and mark regular 2X12s purchased from your local lumber yard and using a handheld power planer shape them into an airfoil/blade profile. You will be building the rotor hub and balancing the entire rotor assembly. The plans show you how to use a salvaged combine or truck axle, which will become the yaw assembly in which you will be mounting to the bedplate and completing the generator frame. After completing the tail-vane assembly you will be making the nacelle, which will cover the generator, and the electrical enclosure where the control relays and micro-controller will be housed. The wiring diagrams are easy to follow and understand (remember when we used to paint by number, I like to call this “wire by number”). We have included two of these diagrams to help you better understand how it’s wired (we even tell what color to mark your wire so that in the event you have trouble we will be better able to help you troubleshoot). The book has all the dimensions and details for building the 60’ tilt-up tower. The guy anchors, brackets, base footings and details for the cable truss assembly are provided. You will also be building the integrated gin pole that you will use to raise and lower the turbine for maintenance and inspection. You are given test and calibration procedures to insure proper operation prior to start up. Throughout the book where a picture wasn’t quite enough, we added simple CAD drawings and diagrams to help. We designed Breezy 5.5 from the homeowner/builder outward and we asked ourselves these questions. How much generator does it take to offset the average electric bill, as opposed to how much power can we make? How can we design this generator so that it is simple and still capture available power from bulk of the winds (8-25mph) as opposed to capturing power from all winds? How can we limit the power produced from the turbine so that doesn't overheat our generator in high winds and still not have to shut it down? How can we design this generator with "non-wind-turbine" parts so that it can be built and maintained within a budget? And finally, how can we make it strong enough to last for 20 years? We answered all these questions with Breezy 5.5! To see completed turbines and find out more about the turbine: www.prairieturbines.com
The book is very detailed.
This book explains in detail how to build Breezy 5.5 and 10K from components and material. The book has the necessary schematics to wire the motor to relays and the micro-controller. It does not teach you how to build and program micro-controllers, build or rewind motors, make slip-rings, relays, capacitors, or torque limiters. These items are components and producing these components is beyond the scope of this book. |
