Description

technical field [0001] The invention belongs to the technical field of offshore wind turbines, and specifically discloses a device and a measurement method for measuring power characteristics of offshore wind turbines. Background technique [0002] The offshore environment is harsh, and the power generation performance of wind turbines is not only affected by the wind, but also by factors such as waves and currents. Different directions and intensities of waves and currents will affect the control reliability and stability of the units, thereby affecting the performance of the units. power characteristics. At present, the test method of power characteristics of offshore wind turbines still uses the test method of onshore wind turbines, and only takes wind as the evaluation factor affecting the power output characteristics of generators, thus reducing the reliability of type certification of offshore wind turbines. This method not only makes it difficult for offshore wind tu...
