Gamesa G87-2.0 MW Wind Turbine

Maximum output at minimum cost per kWh for medium wind sites:

Class IIA/WZII.

Pitch and variable speed technology to maximize energy production.

Production of lighter blades using fiberglass, carbon fiber and prepreg method.

Compliance with the main international Grid Codes.

Aerodynamic design and Gamesa NRS® control system to minimize noise emissions.

Gamesa WindNet®: Remote monitoring and control system with Web access.

Mechanical design

Drive train with main shaft supported by two spherical bearings that transmit the side loads directly to the frame by means of the bearing housing. This prevents the gearbox from receiving additional loads, reducing malfunctions and facilitating its service.

Lightning protection

The Gamesa G87-2.0 MW wind turbine generator uses the "total lightning protection" system, in accordance with standard IEC 62305. This system conducts the lightning from both sides of the blade tip down to the root joint and from there across the nacelle and tower structure to the grounding system located in the foundations. As a result, the blade and sensitive electrical components are protected from damage.

Gamesa WindNet®

Gamesa SGIPE and its new generation Gamesa WindNet® (wind farm control systems), developed by Gamesa, that allow realtime operation and remote control of wind turbines, meteorological mast and electrical substation via satellite-terrestrial network. Modular design with control tools for active and reactive energy, noise, shadows and wake effects. TCP/IP architecture with a Web interface.

Noise control

Aerodynamic blade tip and mechanical component design minimize noise emissions. In addition, Gamesa has developed the Gamesa NRS® noise control system, which permits programming the noise emissions according to criteria such as date, time or wind direction. This achieves the goals of local regulation compliance as well as maximum production.

Brake

Aerodynamic primary brake by means of full-feathering blades. In addition, a hydraulically-activated mechanical disc brake for emergencies is mounted on the gearbox high speed shaft.

Control system

The Generator is a doubly fed machine (DFM), whose speed and power is controlled through IGBT converters and PWM (Pulse Width Modulation) electronic control.
