The method consists in determining at least one of wind turbine operating conditions or parameters related to pitch activity 116-119; determining if lubrication is needed depending on at least the operating conditions or the pitch activity parameters 116-119; and causing lubrication of the pitch blade bearing if lubrication is determined to be needed. Lubrication may consist in injecting grease during a period of time and causing the blades of the wind turbine to be rotated if necessary during grease injection. The device includes means for determining wind turbine operating conditions, means for determining parameters related to pitch activity, a wind turbine main control 100 for determining if lubrication is needed depending on operating conditions and pitch activity parameters 116-119, and means for causing lubrication of the pitch blade bearing if lubrication is needed. |
