Sany’s SE 16520 is a high speed double-fed wind
turbine generator features high power generation and high reliability, low
construction cost, and low maintenance costs. It has six specific characteristics.
1. Sany remarkably improves the
turbine speed regulating range, allowing the turbines to run at optimal
capacity, while improving the power curve, power generation capacity and reducing
the cut-in speed and rated wind speed.
2. The wind turbine generators can
automatically adjust the relationship between power and rotation speed to adapt
to environmental changes, such as air density, temperature and humidity, and
other factors through improvement of the control algorithm. This means few
errors and will perfectly match the turbine operation parameters and actual
environmental condition, aerodynamic and mechanical characteristics.
3. The stator side of the doubly
fed wind power generator outputs voltage and frequency the same as those of the
power grid. This is accomplished by magnetizing the rotor side of the doubly
fed wind power generator, and carrying out independent active and reactive
decoupling control according to grid requirements.
4. Hydraulic cylinders provide
powerful driving force, fast response, and high precision pitch control.
5. Sany has the patent of the
real-time yaw control technology which provides precise horizontal orientation with
a low impact start and stop system.
6. The wind turbine generator uses
high strength materials with flexible structural design, making it adapt to
different blade types, hubs and gearboxes. This helps reduce cost in construction,
transportation and services.
