People show an increasing tendency towards having their own wind turbines for generating their own electricity and also for reducing their contribution to environmental problems as a result of carbon based sources of energy.
Wind turbines and their operation
A wind turbine is really a machine that can convert the kinetic energy of the wind into electrical energy. Blowing wind rotates the blades of the turbine as well as the mechanism inside it can generate electricity upon this rotation. Wind turbines have mainly two types. Horizontal axis and vertical axis wind turbines. They both have advantages and disadvantages but horizontal axis ones are more common due to higher efficiency.
Individual wind turbines
Individual turbines can be applied for various purposes ranging from supplying energy for a few small electrical devices where grid connection will not be possible to meeting part of the energy demand of a property, a farm or even a production facility. Individual generation systems can be standalone or grid connected. The energy output from a standalone Small Wind Turbine can be directly used. However, in grid connected systems excess electricity produced can be supplied to the national grid system. In Ireland, you will get chance to be purchased the extra electricity you supply to the grid approximately 500kW. Individual wind turbines can range from as small as 50W to as large as 3 MW, according to their reason for use.
Individual wind turbines for domestic use
Unlike large industrial wind turbines, these turbines have smaller dimensions that make them right for using in relatively smaller areas. Their capacities range from as small as 50 watts to up to 50 kilowatts and their prices vary based on their sizes, types and manufacturers.
What you can do for installing a small wind generation system?
* Initially you must decide whether you really need a tiny scale wind turbine for your energy needs. Sometimes just saving some energy can lower your debts but if the reason for considering a small turbine is being in off-grid areas you can go on to another steps.
* Inspect your site or maybe your building (for rooftop turbines) to find out whether it be suitable for installing a wind turbine. You need to have enough space to set up a turbine with no wind being blocked by other buildings or obstacles.
* Determine your power needs. Your utility bills will probably be the best references.
* See if the area you will install your turbine is windy enough. You can always find wind measurement data in wind energy associations’ websites for your area.
* According to your power requirement as well as the wind potential in your town, decide the capability and kind from the turbine you will want.
* Your small scale wind product is expected to get a ROI period of maximum fifteen years. Economic lifetime of a small wind turbine without changing the key elements is estimated to become about two decades and proper maintenance improves this. However, maintenance needs of small wind turbines are anticipated to get minimal.
* Have any permits required in the area.
* You will probably need to have a contractor for erection, assembly, electrical connections of the wind turbine. However, should your turbine is micro scale, you can do these jobs by yourself as well. You can find domestic scale wind turbines and in addition 400W or 1 kW self installed turbines and accessories on windturbines.ie.
Individual wind turbines for industrial uses, i.e. factory sites
Turbines for industrial uses have capacities between 500kW to 3 MW. It is possible to generate electricity for wind speeds between 3 m/s and 25 m/s. For times that the wind is not really blowing, one can still get electricity from the grid. This can lead to additional revenue as well as your reduced power bills.
Steps towards a wind turbine installation in your factory site:
The steps that ought to be designed for installing an industrial scale wind turbine are approximately exactly like those for installing a domestic turbine. The sole difference is that they require more expertise. So it might be a smart idea to require a turnkey service from a specialist company in order to not experience any problems. The stages for a turbine installation are outlined below:
* Wind Measurement: When your annual electricity generation depends mainly on wind speed, this step is of vital importance to be able to forecast your energy production. You can never know what you should generate with no knowledge of what you have in hand.
* Feasibility studies: This will be a detailed study to let you know rskxmv your proposed system is a feasible project or not.
* Grid connection studies: This task assesses grid connection possibilities for the proposed wind turbine.
* Permission: Planning and installing of your wind turbine will need some permits on planning stage and during installation. Failure to obtain these permits may lead to legal enforcement.
* Project budget planning: What you will have to spend for the wind turbine project from starting out the conclusion is a crucial item in every kind of planning business.
* Procurement, commissioning and installation: All of your equipment and staff needs for any turnkey project.
* Post-sales services: Issues like warranty, technical service, and maintenance.
