Indoor SVG Composition
TSVG system mainly consists of starting cabinet, power cabinet and control cabinet.
Soft start cabinet
With a simple structure, the starting cabinet mainly consists of vacuum switch and charging resister, dry-type reactor etc. It is utilized to connect SVG and grid to realize power buffering. Meanwhile, it reduces the current ripples of SVG.
After the main circuit breaker closing, the system voltage charges the DC supporting capacitor of the power module though charging resister. The charging resistor can avoid the damage of IGBT module or DC supporting capacitor because of high starting current. After charging, the control system will close the power network vacuum switch.
Power cabinet is mainly composed of power modules.
