Reactive power compensator comprising N inverters in parallel, N banks of capacitor(s) and a means for connecting the banks via passive electrical components

摘要

The compensator (10) has electric terminals (12) connected with an electric alternating current network (11). Bidirectional voltage inverters (16) are parallely connected with each other and connected to corresponding capacitors (14), and convert direct current into alternative current. A first input terminal (26) and a second input terminal (28) of each inverter are connected to the corresponding capacitors. A capacitor voltage balancing device (18) comprises a unit (32) for electrically connecting the first input terminal of the inverters to resistors (36). One of the resistors is connected in series with an electromagnetic reel.
