TRANSCRIPT
GamesaG128-4.5 MW
A4.5MWratedpowerwindturbine with lower Cost ofEnergy which is as easy totransport and install as a2.0 MW model
Class IIA/WZII.
Individual pitch and multivariablecontrol minimize weight, loadsand noise.
Sectional blade for easy transportand installation.
Permanent magnet synchronousgenerator and full convertertechnology to meet the mostdemanding grid code requirements.
Light weight, high performancemodular drive train.
Gamesa WindNet® advancedtechnology for wind farm controland monitoring.
Advantages
G128-4.5MW
* Measured at generator output terminals, on the low voltage side before the transformer, atrated grid voltage.
Flexifit® and the modular design of itscomponents allow the Gamesa G128-4.5 MWwind turbine to be transported and assembledusing similar resources as are required for a2.0 MW model.

FlexiFit®The FlexiFit® crane, coupled to the nacelle, isused as an assembly and service tool to hoistand lower main nacelle modules such as thedrive train, generator and hub. Using this devicemakes it possible to assemble and servicewind turbines without large cranes, providinga manageable and cost effective alternative totraditional hoisting methods.
GridMate®The Gamesa G128-4.5 MW wind turbine electricalsystem uses a permanent magnet synchronousgenerator and a full converter. The systemcomprises parallel modules which continue tofunction in the event of individual failure. GridMate®
complies with the most demanding grid connectionrequirements.
State of the art technology in wind turbine design and developmentTransport and Assembly
The advanced technology used in the Gamesa G128-4.5 MW wind turbine makes for a more reliablesystem. Technological developments applied to improve reliability include load-reducing multivariablecontrol, drive train with no high-speed rotating components and modular electric power system whichallows partial operation of the unit and also isolates the mechanical train from loads caused by voltagedrops.
MultiSmart®The wind turbine control systemuses the data gathered to regulateindividual blade, moderatingvibration and reducing up to 30%of load on some components.
InnoBlade®Gamesa’s new aerodynamic profiles reduce noiseand maximize production. The Innoblade® ismanufactured using a combination of materials in apioneering structure that reduces weight. Currenttooling and equipment used to transport 2.0 MWmodels to the site are also suitable for this innovativesectioned-blade.
CompacTrain®The G128-4.5 MW drive train designed by Gamesaconsists of a semi-integrated main shaft and a 2-stagegearbox with mid-speed range output. This integrateddesign makes the unit more compact, with fewercomponents. Mid-range speed output improvesreliability with no high-speed rotating mechanicalcomponents.
ConcreTower®ConcreTower® is a concrete/steelhybrid tower designed for the G10Xplatform. The prefabricated concretesections are easy to transport andassemble on site.
