Abstract
A device for testing a power module of a set of power modules connected together includes reactive power compensation means capable of compensating the reactive power transferred between a tested power module and the other power modules, and means for monitoring the power generated by the tested power module including means for comparing said generated power with at least one threshold value.
Claims9
A device for testing a power module of a set of power modules connected together, each power module being a generator module, the device comprising:
- a plurality of reactive power compensation units, each reactive power compensation unit disposed in each power module of the set of power modules, wherein each power module is operable in a reactive power compensation mode excluding a power module under test, and each reactive power compensation unit being configured to compensate a reactive power transferred between the power module under test and other power modules of the set of power modules, and
- a plurality of control units, each control unit being disposed adjacent to each power module and configured to control power generated by the power module, wherein each control unit comprises a comparator unit configured to compare said power generated by the power module under test with at least one threshold value.
A method for testing a power module of a set of connected power modules, wherein the method comprises:
- compensating, via a reactive power compensation unit of a plurality of reactive power compensation units, disposed within each power module of the set of connected power modules, each power module being operable in a reactive power compensation mode excluding a power module under test, a reactive power transferred between the power module under test and other power modules of the set of connected power modules,
- controlling, via a control unit of a plurality of control units, being disposed adjacent to each power module, power generated by the power module and comparing, via a comparator unit of the control unit said power generated by the power module under test with at least one threshold value.
