WIND-DRIVEN GENERATOR AND CONSTRUCTION METHOD THEREOF

摘要

A wind-driven generator whose nacelle (3) is weight-reduced for using a versatile crane when constructing the wind-driven generator. The wind-driven generator has a yaw system (10A) equipped with a yaw driving device (15A), a yaw slewing ring (11A), and a yaw brake (20A) and slewing the nacelle (3) installed at the upper part of a support (2) according to the direction of the wind.
