SANY SE14625 2.X low wind speed wind turbine generator system
Product Feature
High can match the industry's highest 140 m Tower
_Vibration control strategy of unit:Control the natural frequency of quick avoidance of the unit,Avoid resonance of the tower;
_Tower damping:Adopt active adding resistance technology,Rapidly decaying unit amplitude,And that load reduction of the tow barrel is realized;
_ High reliability:Availability up to 99 percent% Above;
High Power Coverage 2.0 - 2.5 MW
_ Large sweeping area per kilowatt,Reaching 6.6m 2 /KM;
Long matching rotor diameter 141~146 blades
_Optimum blade design:Wide range of blade tip speed ratio,Theory Cp Up to 0.Over 49;
_High reliability:Blade with leading edge protection,With lightning protection、De-icing and other functions;
Light load reduction、Structural optimization
_Lightweight design of the tower:Adopt Bladed、Samcef Structural parameters of tower drum、The frequency is optimized;
_Weight per kW 0.132t, The lightest in the industry;
Intelligent precise synchronous variable pitch、Grid friendly、Highly integrated intelligent control
_Intelligent control:Intelligent tip speed ratio dynamic optimization、Intelligent Wind Direction Optimization Increases Power Generation by 10%;
_Intelligent load shedding:Control strategy based on the combination of European latest level with European Research Institute,Ultimate load Mxy Decrease 35%,Fatigue loadMxy Decrease 18%;
_Push out“Intelligent”+“Digitize”Overall ecosystem of wind turbine:Sany European Research Institute introduces advanced control technology and development means,Fusion intelligent control、Intelligent sensing、Predictive control、Digitalization and many other cutting-edge technologies,Intelligent optimization control technology、Supporting independent pitch technology、Advanced control strategies such as laser radar technology and flexible tower control technology,Build industry-leading control system platform。
