Abstract

See full text

A method for rotating a hub of a wind turbine in an inching operation to rotate the hub includes reconfiguring the generator from normal operation by coupling a first string of a first electrical phase of the stator in series with a second string of a second electrical phase of the stator, the first and second strings comprising one or more coils coupled in series. Current is provided from a power converter to the first and second strings o rotate the hub. The generator includes a first and a second winding system, each including a plurality of electrical phases in the normal operation. The first string of the first electrical phase is part of the first winding system in normal operation, and the second string of the second electrical phase is part of the second winding system in the normal operation.
