The development of wind energy alleviates the issue of energy shortage at present, but the development technology of offshore wind energy is not mature, so the research on the performance of offshore wind turbine system is the key to develop clean wind energy. Based on the theory of time-domain coupling analysis, this paper studies the hydrodynamic performance of offshore wind turbine under environmental load, and probes into the hydrodynamic performance of offshore wind turbine system. It is found that the offshore wind turbine will stop operation when the wind speed is greater than 28m/s, and the calculation results show that the offshore wind turbine in this study meets the requirements of the specification for the stability of large inclination angle. The environmental load determines the initial offset of the offshore wind turbine system, in which the mean wave drift force is much smaller than the offshore wind force. With the increase of wind speed, the wind turbine system can automatically adjust the pitch of the blades. When the wind speed exceeds the limit wind speed, the wind turbine stops working. When operating at rated power, wind turbine occurs under the action of wind force will have an offset, which is large. The offset of wind force and wind turbine decreases with the increase of wind speed. This study provides a theoretical basis for the application of offshore wind energy development system.
