Abstract

The invention relates to a maintenance method of a wind turbine generator set. The wind turbine generator set comprises a tower, an engine room installed on the tower, and an impeller installed on the engine room, wherein the tower is fixed to a transport ship. The impeller and the engine room are sequentially demounted, and the engine room and the impeller are sequentially mounted so as to complete the maintenance of the whole wind turbine generator set, thereby lowering the maintenance cost and difficulty of the wind turbine generator set, and enhancing the economical efficiency and safety for constructing the wind field.

Description

technical field [0001] The invention relates to the technical field of wind power generation, in particular to a maintenance method for a wind turbine. Background technique [0002] With the rapid development of the wind power industry, the openness of onshore wind farms is becoming increasingly saturated. Offshore wind farms, with their advantages of high wind speed, low turbulence, and small wind shear, have become a field of wind power that urgently needs to be developed. In recent years, the number of wind farms in various places has continued to increase. While onshore wind farms have continued to develop, offshore wind farms have also begun to be constructed. At the same time, with the development of wind power technology and the gradual improvement and improvement of unit performance, wind turbines are becoming more and more economical and efficient, and the capacity of a single unit is also increasing. [0003] However, with the gradual increase in the capacity of a...
