AUTOMATED METHOD AND APPARATUS FOR TESTING A POWER CONVERTER

摘要

A method and apparatus for testing operability of a power converter with an existing power conversion assembly of a renewable energy system is disclosed. The method includes transferring a first pulse of energy from an existing power conversion assembly to a power filter of the power converter through first cells within a bridge circuit of the power converter. Another step includes determining a first current-voltage feedback associated with the first pulse. A next step includes transferring a second pulse of energy from the power filter to the existing power conversion assembly through second cells within the bridge circuit such that a portion of the first pulse moves back to the existing power conversion assembly. Another step includes determining a second current-voltage feedback associated with the second pulse. The first and second current-voltage feedbacks are compared with nominal tolerances of the power converter to ensure the power converter is operating properly.

1. A method for testing operability of a power converter with an existing power conversion assembly of a renewable energy system, the power converter having a bridge circuit and a power filter, the method comprising:
transferring, by the existing power conversion assembly, a first pulse of energy from the existing power conversion assembly to the power filter through one or more first cells within the bridge circuit; determining, by a converter controller, a first current-voltage feedback associated with the first pulse of energy; transferring, by the existing power conversion assembly, a second pulse of energy from the power filter to the existing power conversion assembly through one or more second cells within the bridge circuit such that at least a portion of the first pulse of energy within the power filter moves back to the existing power conversion assembly; determining, by the converter controller, a second current-voltage feedback associated with the second pulse of energy; and, comparing, by the converter controller, the first and second current-voltage feedbacks with nominal tolerances of the power converter to ensure that the power converter is operating properly.
