Abstract: A benchmark state space model construction method for an offshore wind turbine is provided. The benchmark state space model is constructed by the modal information of the first several orders of the high-order finite element model of the offshore wind turbine. Since the benchmark state space model is only established by the first several orders of the high-order finite element model, the time domain analysis of the offshore wind turbine using the benchmark state space model instead of the high-order finite element model can improve the calculation efficiency and reduce the calculation cost. The benchmark state space model construction method solves the problem of low computational efficiency and high computational cost of time domain analysis of offshore wind turbines using high-order finite element models due to the excessive number of high-order finite element units in existing technologies.
