摘要:
Provided is a method for determination of a location of a short circuit fault in a generator arrangement, wherein the generator arrangement includes an electrical machine and at least one channel, wherein the or each channel includes a breaker, a converter unit and a set of stator windings of the electrical machine connected to the converter unit via the breaker, wherein upon an occurrence of a short circuit in a channel, the connection between the set of stator windings and the converter unit interrupted by opening the breaker, wherein depending on at least one measured signal of a measurand, wherein the measured signal is measured by at least one sensor of the electric machine and wherein the measurand describes a torque ripple of the electrical machine, either the electrical machine or the converter unit of the channel is determined as location of the short circuit fault.
