STATCOM system for providing reactive and/or active power to a power network

摘要

A static compensator system for providing reactive and/or active power to a power network. The system includes a static compensator, which has a DC capacitor U_d and a voltage source converter. The static compensator is connected to an energy storage device. The system further includes a booster converter device connected in series with the energy storage device and in parallel with the DC capacitor U_d of the static compensator. The booster converter device and the energy storage device are further connected in parallel with the voltage source converter of the static compensator.
