【Abstract】 This paper introduces the DFIG system,the principle of the converter,and the virtual oscilloscope technology which can be used in the fault diagnosis of the wind power converter. A fault diagnosis example of the wind power converter based on virtual oscilloscope is discussed in detail. It is found that the result of real exploration is consistent with that of fault diagnosis. The technology of converter fault diagnosis based on a virtual oscilloscope is a powerful tool to deal with the faults of the wind power converter and primary equipment.更多还原
