  • Wind power plant concepts and performance indicators

    Wind turbines are usually placed in clusters called wind farms, with sizes ranging from a few MW (sometimes even a single wind turbine is sold, for instance to a private investor or to give power to an energy intensive factory like a cement plant) up to several hundred MW. These clusters are connected to the…

  • Power curve: what is it and how to measure it

    A power curve is a relationship between free wind speed at the WT location and the associated expected power being produced. Power curve warranties are often included in contracts, to assure the wind turbine performs according to specification. Here you have an example of how it looks like: It is measured following international standards to…

  • Wind turbines blades materials

    A fundamental aspect in the wind blades design is the choice of the correct materials, because several parameters (weight, load and fatigue behaviour, physical properties, etc.) are influenced by this basic decision. Several years ago materials as varied as wood, steel and aluminium where used to produce wind blades. The first wind blades where made…

  • Wind turbine tower

    Towers are an important element in the structure of a WTG, not only for structural reasons (they transmit the loads from the nacelle to the foundation) but also for economical reasons: they highest the tower, the biggest the amount of energy produced. For instance, with an increase of 20 meters from the standard 80 meters…

  • Windfarm SCADA system characteristics

    SCADA is an acronym that stands for “Supervisory Control And Data Acquisition”. It is a fundamental tool to monitor and control several parameters of the WTGs, and it’s usual to sell it together with the turbines. It allows combining, in a single point of control, all the info about WTGs, meteorological mast and substation, serving…

  • WTG earthing system

    A wind farm earthing system is designed for two different functions: to protect human beings and the components in case of power systems fault, and to protect them in case of a lightning hitting the structure. Wind turbines have a considerably high possibility of being struck by a lightning during their lifetime. For this reason…

  • WTG Components: an introduction

    Blades: Most wind turbines have three blades, though there are some with two blades and even with a single blade. Blades are generally 30 to 50 meters (100 to 165 feet) long, with the most common sizes around 40 meters (130 feet). Longer blades are being designed and tested, but the main problem with bigger…
