SYSTEM AND METHOD FOR CONTROLLING AN AC/DC CONVERTER
摘要
The invention relates to a control of a power converter (1) with an MMC topology. The inputs to the converter are the branch voltages U1...U6. These voltages are obtained by a linear combination (12) of the four types of main voltages: DC main voltages UDC1, AC main voltages UAC1 and UAC2, internal main voltages UM/1 and UM/2 and relative main voltages UMR1. AC and DC main voltages are respectively used to control the power exchanged with AC and DC circuits or grids connected to the converter and to keep the control the total energy stored in the converter. Relative main voltages are used to control the relative voltage between independent circuits. Internal main voltages are used to control completely the balance of the energy stored in the converter branches. This is accomplished by selecting values for the AC and DC components of each main voltage.
