In view of the long grid connection period in the construction of current offshore wind power project

a kind of self-starting wind turbine grid connection method is proposed and on which a set of wind turbine grid-connected debugging device is developed. The device can be installed on the offshore booster station platform. The stable power is supplied for the wind turbine through submarine cable before the power of large network is delivered to the offshore booster station. During this period

the static/dynamic debugging and related calibration work of the wind turbine is completed in advance. After the formal power source is delivered to the offshore booster station

the wind turbine is connected to the grid directly

which shortens greatly the construction period of offshore wind power projects and helps to the wind turbine to interconnect and generate power in advance

create objective economic value

speed up grid connection of clean energy and achieve the energy and environmental strategic goals of “carbon peak and carbon neutrality”. At present

the technology has been applied in many offshore wind farms in Rudong

Jiangsu. And the advancement and effectiveness of the developed system and the proposed method are verified by the filed test data.
