Abstract

The invention discloses a high-temperature superconducting material-based full-lifetime evaluation method of an offshore wind turbine. The method comprises the steps of determining a full-lifetime evaluation period; limiting boundary conditions; determining asset allocation; setting offshore wind turbine parameters; building an evaluation index library; carrying out evaluation index sensitivity and uncertainty analysis; and determining comprehensive evaluation. The used high-temperature superconducting material is the second generation of high-temperature superconducting material; and a superconducting layer is manufactured by a thin-film vacuum deposition technology and comprises six layers in all, namely a copper bottom layer, a hastelloy alloy C276 layer, a yttrium barium copper oxide layer, a nano layer, a silver layer and a 20micron copper top layer separately. By the method, the key index of affecting the full-lifetime of the offshore wind turbine can be determined; management planning decision is facilitated; and equipment is in a good environment-friendly working state, so that the target of the minimum full-lifetime energy consumption is achieved.

Description

technical field [0001] The invention belongs to the technical field of offshore wind power generators, and in particular relates to a method for evaluating the life of an offshore wind power generator based on a high-temperature superconducting material. Background technique [0002] Wind energy is the fastest growing energy source in the world. Especially in the last ten years, offshore wind energy is the fastest-growing field of wind energy utilization, and since stronger and more stable winds can be generated offshore, it is possible to build large-scale wind farms. It is foreseeable that in the next ten years, the installed capacity of wind power will grow more rapidly. In addition, compared with onshore wind power generation, existing theoretical research and engineering practice have proved that large offshore wind power generators not only have a larger installed capacity, but also lower power generation costs. [0003] The low or even zero resistance of high-temper...
