POWER INVERTER, CONTROL UNIT FOR POWER INVERTERS AND NETWORK OF POWER INVERTERS

摘要

According to a first aspect of the invention, a power inverter for converting source currents or voltages into alternating currents or voltages to be injected into a supply grid comprises a harmonics compensator configured to detect one or more harmonics of the fundamental frequency of the electrical supply grid and to control the alternating currents or voltages to be injected in such a way as to selectively modify the voltage of at least one of the one or more detected harmonics in accordance with one or more respective targets. A communication interface allows the power inverter to join a network of power inverters. The harmonics compensator is configured to share some or all of its operating parameters over the network and to adjust the one or more targets depending on instructions and/or operating parameters communicated to it via the network. A second aspect of the invention relates to a control unit for centrally controlling such power inverters.
