Suzlon Energy offers the Suzlon S88-2.1 MW wind turbine suitable for use in medium wind environments. The wind turbine utilized in this model features robust construction and incorporates pitch regulated blade operation, and a 2200 kW rated three stage gear box that is flexibly connected to the asynchronous induction generator.
The flexi-slip system utilized in the S88-2.1 MW model offers efficient load and power control. The operation of the turbine is competently managed by the Suzlon controller.
The rotor incorporated in the S88-2.1 MW wind turbine measures 88 m in diameter, offers a swept area of 6082 m² and utilizes an electrically regulated full-span blade pitch system allowing faster and efficient pitching of blades. The rotor blades are made of epoxy bounded fibre glass and fixed over a four sectional tubular tower. The rated power of this wind turbine is 2.1 MW, its cut-in wind speed is 4 m/s, rated wind speed is 14 m/s and its cut-out wind speed is 25 m/s. The hub utilized in this wind turbine measures 79 m. The asynchronous slip ring type induction generator incorporated in the wind turbine has a rated power of 2100 kW, a rated voltage of 600 to 690 V, and a frequency of 50 / 60 Hz. This generator is air cooled, has class H type of insulation and utilizes a unique flexi-slip offering slip up to 16.67% as slip control.
The S88-2.1 MW wind turbine from the Suzlon Energy utilizes an aerodynamic brake with three independent systems and blade pitching mechanism. It has a hydraulic fail-safe disc brake as secondary brake. This wind turbine incorporates a three stage (one preliminary and two helical) gearbox. The yaw system utilized in the model is driven by three electrical driven planetary drives and utilizes polyamide slide type of bearings.
