Abstract
The present invention relates to a method for operating a power generating assembly in the event of a fault, wherein the power generating assembly comprises a PMG comprising at least first and second sets of stator windings, wherein each set of stator windings is connected to a power converter via a controllable circuit breaker, the method comprising the steps of detecting a fault associated with the first set of stator windings, and lowering, such as interrupting, the current in the second set of stator windings, and, after a predetermined delay, lowering, such as interrupting, the current in the first set of stator windings. The present invention also relates to a power generating assembly being capable of handling such faults, and a wind turbine generator comprising such a power generating assembly.
