Offshore Wind Power Grid-connected Technology Based on Self-starting System

In view of the long period of the current offshore wind power project construction, a self-starting wind turbine grid-connected method is proposed, and a set of wind turbine grid-connected self-starting device is developed based on this method. Through this device, it is available to provide a stable power supply for the wind turbine through the submarine cable before the grid power on the land is delivered to the offshore substation. After the grid power is delivered, the wind turbines are directly connected to the grid, which greatly shortens the construction period of offshore wind power projects, creates considerable economic value. The technology had been applied in many offshore wind farms in Rudong, Jiangsu, and the field test data verified the advancement and effectiveness of the developed system and the proposed method.
