The N80 2,500kW speed-variable wind turbines used at the Havøygavlen Park are of a three-bladed design with an 80m rotor diameter. Operable in wind speeds of 4m/s to 25m/s, their asynchronous, double-fed, liquid cooled generators can provide up to 2,500kW at 660V. Pitch control (via a wind vane-monitored yaw system) is achieved through two geared motors operating on the geared yaw ring. The blades, which turn at up to 19.1rpm, drive a three-stage planetary-spur-gear gearbox with a 1:68.1 gear ratio, in which the bearings and tooth engagements are constantly splash lubricated. The SWT-3.0-101 3000 kW features a new, gearless drive train design with a compact, synchronous generator, excited by permanent magnets. The permanent magnet generator is simple and robust design that requires no excitation power, slip rings or excitation control systems. |
