WD70(77)-1500KW variable pitch (pitch regulated) wind turbine generator system has three blade, windward and horizontal axis impeller, three stage gear box, double fed induction generator (DFIG) and alternative excitation converter. Power control is based on DFIG variable speed constant frequency technology and independent pitch system driven by servo motor. This kind of power control is the main trend of technology with high reliability and accepted and adopted world widely.
1500KW variable pitch wind turbine generator system
- We own full intellectual property rights.
- Impellers are designed by latest aerodynamics research results with optimized structure. The changeable height and diameter of impeller are suitable for using in various wind farms.
- Operations on all weather conditions are preconsidered in design.
- Flexible support structure is used in drive train to make load transmission more stable so as to reduce the noise in gear box and generator operation.
- Advanced pitch system makes maximum use of wind energy, efficiently reduces loads on blades, drive trains and structure components for longer service life.
- Low voltage ride through capability makes wind turbine to keep grid connection even in grid disturbance.
- Multiple protections from independent pitch system and mechanical brakes.
- Advanced control strategy for capturing maximum wind energy, optimizing load and enhancing system performance reliability.
