SANY SE8715 High Speed Doubly-Fed Wtg

Wind Power Solution Provider

Customized Products and Service

SANY custom designs the 1.5MW wind turbine generators to meet your business needs and provides you with 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 can greatly increase 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.

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.

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 low wind speed and generation.

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.

Excellent Adaptability in Plateau

High-efficient radiator with increased safety margin, ensuring that device works in a safe temperature range under full power situation. The air cooling system of the generator adopts a double centrifugal fan cooling scheme, and the convertor is specifically designed for high temperature and high altitude.

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.
