Abstract

The invention describes a condition monitoring arrangement (1) of a fluid-film bearing (20) arranged to support the generator (21, 22) of a direct-drive wind turbine (2), comprising a plurality of bearing activity sensors (10), each arranged to collect bearing activity data (10D) during operation of the wind turbine (2); a local data evaluation arrangement (11, 12) adapted for installation in the wind turbine (2) and comprising a data reduction module (11) adapted to reduce the quantity of collected bearing activity data (10D); and a threshold comparator (12) configured to compare the reduced bearing activity data (10D_red) with a number of threshold values (121) to obtain threshold comparator output (1213, 1214) for use as a basis upon which to control that wind turbine (2). The invention further describes a method of monitoring the condition of a fluid-film bearing (20) arranged to support the generator (21, 22) of a direct-drive wind turbine (2); and a direct-drive wind turbine (2) comprising an instance of the inventive condition monitoring arrangement (1).
