摘要： A hydraulic station in a hydraulic system of a wind turbine includes a tank for storing working fluid, first and second pumps fluidly connected to the tank, first and second flow paths extending from the respective first and second pumps to a hydraulic circuit, and first and second relief valves in fluid communication with the respective first and second flow paths. The first pump and first relief valve are controlled based on maintaining pressure of the working fluid in the hydraulic circuit between a first minimum limit and first maximum limit. If the pressure falls below the first minimum limit, the second pump and second relief valve are controlled in addition to the first pump and first relief valve, with the control then based on a second maximum limit and second minimum limit.

摘要： A method of starting up wind turbine (10) comprises heating first and second components, the first component (32) having a first minimum operating temperature and the second component (42) having a second minimum operating temperature. Heat loss is generated after the second component has been heated to the second minimum operating temperature. The heat loss is transferred to the first component to assist heating the first component to the first minimum operating temperature. The first and second components are cooled after reaching the first and second minimum operating temperatures.
