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 blad e 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 w ind turbine to be rotated if necessary during grease injection. The device i ncludes means for determining wind turbine operating conditions, means for d etermining parameters related to pitch activity, a wind turbine main control 100 for determining if lubrication is needed depending on operating conditi ons and pitch activity parameters 116-119, and means for causing lubrication of the pitch blade bearing if lubrication is needed. |
