STACOM SYSTEM FOR PROVIDING REACTIVE AND/OR ACTIVE POWER TO A POWER NETWORK

摘要

The invention relates to a static compensator (11) system for providing reactive and/or active power to a power network (14). The system comprises a static compensator (11), which comprises a DC capacitor (Ud ) and voltage source converter (10). The static compensator (11) is connected to an energy storage device (12). The system further comprises a booster converter device (13) connected in series with the energy storage device (12) and in parallel with the DC capacitor ( Ud ) of the static compensator (11). The booster converter device (13) and the energy storage device (12) are further connected in parallel with the voltage source converter (10) of the static compensator (11).
