(2) The operation and maintenance cost of onshore wind power plant equipment is low, wind power plant operators generally do not consider cost factors, and compared with the operation and maintenance of onshore wind power plant equipment, the cost of transportation tools required in the operation and maintenance process of offshore wind power plant equipment is high, the reliability of offshore wind power plant equipment is poor, the maintenance frequency is high, and the maintenance cost of offshore wind power plant equipment is high. Therefore, cost factors need to be considered in the operation and maintenance strategy of the offshore wind power equipment. Under the restriction factors, how to design an offshore wind power operation and maintenance evaluation strategy to solve or partially solve the technical defects and obtain an optimal offshore wind power operation and maintenance plan is a big problem which puzzles the offshore wind power industry at present.
