Method and system for determining reserve quantity of spare parts of wind turbine generator

The invention provides a method and a system for determining the reserve quantity of spare parts of a wind turbine generator. The reserve quantity determination method comprises the following steps: acquiring current operation data of a current operation part of a target part of the wind turbine generator and historical life data of a historical use part of the target part, determining the current life data of the current operation part by using the current operation data, and taking the historical life data and the current life data as sample data, and determining a service life model of the target part, and determining the reserve quantity of the spare parts of the target part by utilizing the service life model and the current use quantity of the current running parts. The historical life data and the current life data are utilized to increase the data volume, and the reserve quantity of the spare parts of the target part is determined by determining the life model of the target part, so that the reserve q
