Title:
SEMI-DIRECT-DRIVEN WIND TURBINE GENERATOR UNIT
Document Type and Number:
WIPO Patent Application WO/2023/125640
Kind Code:
A1
Abstract:
A semi-direct-driven wind turbine generator unit, comprising a generator (1), a gearbox (2), high-frequency grounding strips (3), and a protection module. The generator (1) comprises a stator base (11), a stator winding (12) and a rotor assembly (13). The gearbox (2) comprises a box body (21) connected to the stator base (11) and an output shaft (22) rotatably connected to the box body (21); the output shaft (22) is connected to the rotor assembly (13); the box body (21) and the stator base (11) are grounded by means of the high-frequency grounding strips (3), respectively; the protection module can reduce a common-mode voltage on the output shaft (22) so as to reduce a shaft current on the output shaft (22).
