Product Feature
Wind Power Solution Provider
Customized Products and Service
SANY custom designs the 2.0MW wind turbine generators to meet your business needs and provides you with the integrated solutions covering site selection, wind assessment, construction, equipment installation and operation of wind farms.
High Productivity
Optimal CP Operation Technology
The optimal CP operation technology greatly increases the turbine's speed regulating range, thus the turbine can run with optimal capacity before reaching the rated power. This significantly improves the power curve, power generation capacity and reduces the cut-in speed and rated wind speed.
Low Wind Speed Design
Applying to the condition when the annual average wind speed is lower than 5m/s; reducing cut-in wind speed; and increasing generating capability of low speed wind period
Hydraulic Yaw Technology
SANY patented real-time yaw can realize precise orientation, capture maximal wind power, and real-time cast loose, and avoid stranded cable.
Wide Adaptability
Good Grid Adaptability
By magnetizing the rotor side of the double-fed WTG, the stator side of the double-fed WTG can output the same voltage and current as the frequency and phase of power grid voltage and carrying out independent active and reactive decoupling control according to requirement.
Converter/Main Control System
By improving the control algorithm, WTG can automatically adjust the power and rotation speed relationship based on environmental changes (such as air density, temperature and humidity) to increase full-power rectification at a low wind speed and generation.
High Reliability
Low Voltage Ride through Capability
The low voltage ride through test and other certifications guarantee that the turbine can respond rapidly during the reduction of voltage, generate the dynamic reactive power to support the recovery of grid voltage, and the active power is recovered rapidly after clearing the fault.
Overload Avoidance Technology
Based on the load condition of each part of turbine, the operating state can be controlled to avoid operation at its component's limit thus to protect the turbine from damage.
Low Cost
Self-climbing Cranes
This innovative design can realize hoisting and installing of tower, cabin, wind wheel and other large components without using large crawler cranes, helping you save abundant construction time and cost.
Operation and Maintenance Service
SANY makes the "1-2-3-15" service commitment: reply in 1 quarter hour, arrive on site in 2 hours, problem solved in 3 days and serious faults solved in 15 days.
