Reconfigurable power converter module

摘要

Embodiments provide a reconfigurable power converter module for a wind turbine facility adapted to supply electric power to an associated power supply grid. The reconfigurable power converter module includes a frequency converter operatively connected to filter means, wherein the frequency converter and the filter means are mutually reconfigurable so as to suppress internal and/or external resonances or harmonics.

1. A reconfigurable power converter module for a wind turbine facility, the wind turbine facility configured to generate and supply electric power to an associated electrical load that includes a power supply grid, the power converter module comprising:
a frequency converter operatively connected with one or more filters having filter characteristics dependent on an amount of the electrical load, wherein the power converter module is configured to modify a switching frequency of the frequency converter responsive to a change in one or more of the filter characteristics, wherein the power converter module is further configured to operate the frequency converter:
at one or more first switching frequencies for values of the electrical load less than a nominal load value of the power converter module, andat a plurality of second switching frequencies for values of the electrical load between the nominal load value and a first threshold load value that is greater than the nominal load value, wherein the second switching frequencies decrease linearly from a nominal switching frequency corresponding to the nominal load value to a third switching frequency corresponding to the first threshold load value.
