How to Diy Your Own Wind Turbine?

How Wind Turbines Work?

Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetation. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.
The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.
So how do wind turbines make electricity? Simply stated, a wind turbine works the opposite of a fan. Instead of using electricity to make wind, like a fan, wind turbines use wind to make electricity. The wind turns the blades, which spin a shaft, which connects to a generator and makes electricity.

Types of Wind Turbines

Modern wind turbines fall into two basic groups: the horizontal-axis variety, as shown in the photo, and the vertical-axis design, like the eggbeater-style Darrieus model, named after its French inventor.
Horizontal-axis wind turbines typically either have two or three blades. These three-bladed wind turbines are operated "upwind," with the blades facing into the wind.

Sizes of Wind Turbines

Utility-scale turbines range in size from 100 kilowatts to as large as several megawatts. Larger turbines are grouped together into wind farms, which provide bulk power to the electrical grid.
Single small turbines, below 100 kilowatts, are used for homes, telecommunications dishes, or water pumping. Small turbines are sometimes used in connection with diesel generators, batteries, and photovoltaic systems. These systems are called hybrid wind systems and are typically used in remote, off-grid locations, where a connection to the utility grid is not available.

Diy wind turbines
Measures the wind speed and transmits wind speed data to the controller.
Most turbines have either two or three blades. Wind blowing over the blades causes the blades to "lift" and rotate.
A disc brake, which can be applied mechanically, electrically, or hydraulically to stop the rotor in emergencies.
The controller starts up the machine at wind speeds of about 8 to 16 miles per hour (mph) and shuts off the machine at about 55 mph. Turbines do not operate at wind speeds above about 55 mph because they might be damaged by the high winds.
Gears connect the low-speed shaft to the high-speed shaft and increase the rotational speeds from about 30 to 60 rotations per minute (rpm) to about 1000 to 1800 rpm, the rotational speed required by most generators to produce electricity. The gear box is a costly (and heavy) part of the wind turbine and engineers are exploring "direct-drive" generators that operate at lower rotational speeds and don't need gear boxes.
Usually an off-the-shelf induction generator that produces 60-cycle AC electricity.
Drives the generator.
The rotor turns the low-speed shaft at about 30 to 60 rotations per minute.
The nacelle sits atop the tower and contains the gear box, low- and high-speed shafts, generator, controller, and brake. Some nacelles are large enough for a helicopter to land on.
Blades are turned, or pitched, out of the wind to control the rotor speed and keep the rotor from turning in winds that are too high or too low to produce electricity.
The blades and the hub together are called the rotor.
Towers are made from tubular steel (shown here), concrete, or steel lattice. Because wind speed increases with height, taller towers enable turbines to capture more energy and generate more electricity.
This is an "upwind" turbine, so-called because it operates facing into the wind. Other turbines are designed to run "downwind," facing away from the wind.
Measures wind direction and communicates with the yaw drive to orient the turbine properly with respect to the wind.
Upwind turbines face into the wind; the yaw drive is used to keep the rotor facing into the wind as the wind direction changes. Downwind turbines don't require a yaw drive, the wind blows the rotor downwind.
Powers the yaw drive.

How to choose a home wind generator?

How to choose a home wind generator?

You’re about to make the big decision: should a wind generator be in your future? You’ve analyzed your resources, both environmental and monetary, and weighed the pros and cons of having a wind generator. The only question left is: which system should you choose?


“what do you recommend?” is the most frequently asked question that I get. The answer—it all depends on your situation. I can honestly say that,properly specified and installed, any one of these machines will do a fine job of producing electricity for you for many years, in the right location.Notice the qualifiers. If you install a light duty machine where the winds are severe, even for part of the year,you are asking for trouble. If you install a light duty machine on a short tower where turbulence will be an issue, you are asking for trouble. If you install a machine with lots of moving parts, knowing full well that you have no intention of climbing the tower to do maintenance and repairs, you are asking for trouble. If you never do routine maintenance on your car or house, what makes you think you’ll do it on your wind generator?

All of these wind generators have their own personalities and idiosyncrasies, just like the cars wedrive. And, just like the cars we drive, they come in a variety of shapes and prices. Finally, just like the cars we choose, they all will get us from point A to point B.However, not all cars, nor all wind generators, are created equal. As the saying goes, “You get what you pay for.” Quality always comes at a price. To quote longtime wind energy user and HP editor Ian Woofenden,“Remember, what you want is value. I put high value on low maintenance, long-term performance. You do not want to buy bragging rights to the highest peak output at the lowest price. Instead you want the most energy put into your battery or the grid for as many years as possible. That doesn’t come cheap.

Solar and Wind Hybrid Power System,solar wind hybrid system, wind hybrid system, solar wind hybrid power system, solar wind power.Solar and Wind Hybrid Power System,solar wind hybrid system, wind hybrid system, solar wind hybrid power system, solar wind power.
Components: solar PV+ wind turbine. We take power both from sunlight and wind, in case of cloudy days, to guarantees the coninuous power supply and improve the efficiency of the equipment. Hybrid is very suitable for high-endurable-electricity-consumption project. For example, highways, outdoor research institute, sea boats.
According its advantage-continuous power supply, Off-grid big plant can also adopt solar wind hybrid power system. US, China and many countries keep great support of this project.

Solar and Wind Hybrid System


Suneco provide Hybrid Solutions that are powered by sun and wind, just in order to guarantee that the power is enough to be charged in the solar battery everyday, if some day there is sunlight but without the wind energy, the solar panel charge the battery. The other way round, if some day there is wind energy but without the sunlight, the wind turbine can charge the power to the battery. When someday both wind & solar energy is enough, both can charge the battery. When the night is coming, the wind turbine is also can continue to work for supply the power to the system, so we sure the system will be popular in the coming future.

We have standard hybrid systems available to meet your power needs. We can also tailor a system to suit should you have a smaller or larger power requirement.
Hybrid systems are designed to be operated “off the grid” (i.e. not connected to a commercial power distribution system) which makes them ideal for stand-alone operation. Electronic controllers manage the multiple power sources and monitor the status of the batteries. If the reserve runs low, the controller automatically starts the generator to supply power and charge the battery bank.

Main Application:

A family with 5-10 persons
Remote or municipal power unavailable area
Any Solar energy available place
Seaside and hill with wind energy area
Radio/TV/Mobile Transmitting station in field or mountains
Emergency situation

Features:

Use the green and inexhaustible energy from sun and wind
Free from smoke and pollution
Advanced design and compact body
Safety and easy to installation and operation
Excellent protections and indications
Possible for expend the system in the future
Provides DC and AC output for variously applications

Our packaged systems are ideally suited to remote homes, schools and other off-grid applications. They can also be retrofitted to existing diesel-generator systems to save on high fuel costs and minimise noise.

Integrating Solar and Wind Technology into your electrical power project can result in higher efficiency, easier maintenance and increased reliability.

Hybrid electric systems combine wind and PV systems to make the most of the area's seasonal wind and solar resources; with wind relatively more available in winter months and at night time, and solar relatively more available in summer months and during winter's sunlight days. These hybrid systems provide a more consistent year-round output than either wind-only or PV-only systems and can be designed to achieve desired attributes at the lowest possible cost.

The major advantage of solar / wind hybrid system is that when solar and wind power productions are used together, the reliability of the system is enhanced. Additionally, the size of battery storage can be reduced as there is less reliance on one method of power production. Often, when there is no sun, there is plenty of wind.
System include: 

1. PV Array: A number of PV panels connected in series and/or in parallel giving a DC output out of the incident irradiance. Orientation and tilt of these panels are important design parameters, as well as shading from surrounding obstructions.

2. Wind turbine: This is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home's electrical system.

3. Hybrid controller: control battery bank charge and discharge reasonable and safety.

4. Battery bank: can be a single battery or multiple batteries connected together to create essentially one large battery of the required voltage and amp-hour capacity. In some ways the battery configuration and capacity are the most important electrical power decision to make, and a wise choice can help guarantee a steady supply of electrical power as well as a system that is simple to operate and maintain.

5. Inverter: A power converter that inverts the DC power from the panels into AC power.

6. Loads: Stands for the network connected appliances in the building that are fed from the inverter (AC loads), or from the battery bank (DC loads).
