How It Works?
Wind Power Plants – Modern Wind Energy Generation Systems
A wind power plant is an installation that generates electrical energy using generators driven by wind power. Wind power plants – including small residential systems as well as larger off-grid or hybrid setups – are considered one of the most environmentally friendly sources of renewable energy. During electricity production, no fossil fuels are burned, which means zero emissions of exhaust gases and greenhouse gases.
Groups of multiple wind turbines connected with the necessary technical infrastructure are known as wind farms or wind parks. However, our offer includes primarily micro wind power plants and small wind turbines designed for autonomous energy systems.
What is a wind turbine?
A wind turbine (or: wind turbines) is a device that converts the kinetic energy of the wind into mechanical energy, and then into electrical energy. The turbine rotor, rotating under the force of the wind, drives a generator that produces electricity. It is the key component of every wind power plant – both residential and commercial.
Types of wind turbines available in our offer
We offer two main types of turbines, enabling optimal selection according to terrain conditions and energy demand:
- Vertical Axis Wind Turbines (VAWT) – characterized by very quiet operation, high resistance to turbulent winds, and effective performance even at low wind speeds. Perfect for urban areas, built-up zones, and locations with changing wind directions.
- Horizontal Axis Wind Turbines (HAWT) – highly efficient designs with strong energy potential. Most commonly used in residential installations, agricultural facilities, industrial sites, and hybrid systems.
Applications of wind turbines and wind power plants
Small and medium-sized wind power plants and wind turbines are used in many applications, such as power supplies for:
- off-grid installations (autonomous systems without grid connection),
- hybrid systems (wind + photovoltaic),
- residential homes and agricultural farms,
- commercial buildings, warehouses, industrial facilities,
- telecommunication devices, monitoring systems, CCTV cameras,
- street lighting, parking lighting, advertising installations,
- battery charging in mobile, camping, marine and trailer systems.
With a wide range of models – from small 100 W turbines to larger 600–700 W units – it is possible to select a complete wind system tailored to any type of investment.
Why choose a wind power plant?
- production of clean energy with zero CO₂ emissions,
- maintenance-free operation and low operating costs,
- year-round operation – also at night and during winter,
- full energy autonomy in off-grid systems,
- high durability of materials, including carbon-fiber blades,
- possibility of integration with solar panels (hybrid systems).
Wind power plants and wind turbines provide long-term reduction of energy costs, increase energy independence and enable the use of clean, renewable energy sources for many years.
Types of Wind Power Plants – Classification, Applications and Characteristics
Wind power plants come in many variants, and their classification depends on factors such as purpose, power output, construction type and installation location. In practice, there are models designed both for residential use and for commercial or industrial applications.
According to purpose, wind power plants are divided into:
- residential (home) wind power plants – used for powering homes, plots, holiday cabins, off-grid systems and autonomous devices,
- industrial wind power plants – operating as part of wind farms and intended for selling electricity to the grid.
Classification by power output:
- Micro wind turbines – up to 100 W; ideal for small power systems, monitoring, weather stations, LED lighting and off-grid devices,
- Small wind power plants – from 100 W to 50 kW; the most popular for residential and agricultural applications,
- Large wind power plants – above 50 kW; used in industrial-scale energy production.
Classification by installation location:
- onshore wind power plants (land-based),
- offshore wind power plants – characterised by higher productivity due to stable wind conditions.
Definition of a Home Wind Power Plant
A home wind power plant is defined as a complete set of devices for producing and storing electrical energy to supply one or more residential buildings. The system is installed in the direct vicinity of the energy consumers and may operate as a primary or supplementary power source.
Types of Operation Systems in Wind Power Installations
Depending on how the generated electricity is used, two main system types are available:
- ON-GRID system – the wind power plant is connected to the electrical grid; surplus energy is fed into the grid, while deficits are drawn from it.
- OFF-GRID system – an autonomous system using energy storage (batteries); ideal for areas without access to the public grid.
Both system types can be delivered as complete turnkey solutions by BrasiT, including full component selection and system configuration tailored to the customer’s needs.
Construction and Operation of a Wind Turbine
The key element of a wind power plant is the wind turbine. It consists of a rotor mounted at a height of several to several dozen metres, and a generator that converts mechanical energy into electrical energy. The efficiency of a turbine increases with:
- rotor diameter,
- mast height,
- stability and speed of wind conditions.
Thanks to modern materials such as carbon fibre and high-strength composites, the lifespan of today’s turbines reaches 20–25 years.
Dynamic Growth of the Wind Energy Sector
Wind energy has been growing at a rate of 20–30% annually since the early 2000s. The global installed wind power capacity increased from:
- 18 GW in the year 2000,
- 59 GW in 2005,
- 199 GW in 2010,
- 239 GW in 2011,
and today exceeds 1000 GW (1 TW) – proving that this is one of the fastest-growing renewable energy technologies worldwide.
Advantages of Small and Micro Wind Power Plants
- significant reduction in electricity bills,
- power generation 100% from renewable sources with zero emissions,
- the most effective form of renewable energy in temperate climates,
- long service life – up to 25 years,
- available subsidies for companies, farms and municipalities.
