Wind Turbines

Back to dictionary

Wind turbine (wind power plant, WPP) is a device intended to convert airflow power into usable kinds of energy: kinetic, mechanical, electrical.

Wind wheel is the main working unit of a wind turbine. Subjected to wind, it converts the airflow power into mechanical energy of its own rotation by aerodynamic pressure of the airflow on the blades.

Types of wind turbines

Types of wind turbines by application and methods of wind power conversion into other kinds of energy:

  • Wind mechanical plants
  • Wind electric plants (most common)
  • Wind thermal plants
  • Combined-output wind power plants which produce, for example, mechanical and electrical energy.

Wind turbine types by design and number of blades:

  • 2-, 3-, 4-, 5-blade WPPs
  • Bladeless WPPs (vortex turbines).

Wind turbine types by rotation axis orientation:

  • Vertical/rotary turbines — turbines which are square to the ground surface, driven by mild wind
  • Horizontal/vaned turbines (traditional windmill principle) — turbines with rotor axis parallel to the ground surface, high wind power-to-AC/DC conversion capacity.

Wind turbine types by blade material:

  • Metal
  • Textile
  • Polymer
  • Carbon fibre-reinforced plastic (CFRP)
  • Glass fibre-reinforced plastic (GFRP)
  • Composite.

Wind turbine types by offline work capability:

  • Offline wind turbines for sites remote from utilities.
  • Wind turbines co-operating with other energy sources (diesel generator sets, power plants, photovoltaic power stations, etc.) for uninterrupted power supply.
  • Online wind turbines (connected to the public power supply networks).

Wind turbine types by application:

  • Industrial wind turbines intended to supply industrial sites.
  • Domestic wind turbines intended to supply private homes and small homesteads.
  • Commercial wind turbines which produce energy intended to be sold to public networks.


A decision to install a wind turbine as well as the preferred design and type option shall be based on the particular site conditions: average wind speed and duration, strength, predominant direction and turbulence, other weather conditions, terrain.

Welcome!

Our project is for information purposes only. It allows to estimate the cost and quantity of materials and labour required to perform certain kinds of construction works. The project may contain mistakes or invalid data (at the beta stage in particular) and shall be not considered as a guide for action.

We continuously make efforts to expand and complete the knowledge base of our project. Write to us if the types of work you need are not in our catalog and we will add them as soon as possible!

Warning!

  • - All utilities and support structures always must be calculated by duly certified agencies or companies
  • - Utilities and support structures must be built by duly licensed contractors
  • - Prior to start a work, check whether it is licensable or requires special training in your region 
  • - Always observe building regulations and standards of your country
  • - Closely follow the guidelines of the manufacturers of the materials, tools and methods you use
