The invention discloses a method for automatically determining a wind turbine state. The method comprises the steps of establishing a wind turbine state determination model; acquiring real-time data and work order data of the wind turbine; and dividing the wind turbine state into one of the following main states by the wind turbine state determination model: a running state, a standby state, a fault state, a maintenance state or an offline state according to the data of wind turbine state, wind speed and load in the real-time data and the data of a defect management sheet and a maintenance andrepair sheet in the work order data. The method combines the real-time data of the wind turbine and the work order data to overcome the inconsistency of the wind turbine states of different wind turbine manufacturers and different wind turbine models, and can uniformly obtain the real-time state of the wind turbines and provide a basis for wind farm group monitoring and benchmarking management. 本发明公开了一种风机状态自动判断方法，包括以下步骤：
