Static Var Generator (SVG)— Three Phase.jpg

X2

SVG is a dynamic reactive power source, using DSP/IGBT and other high-speed computing components, combined with precision control program, can real-time track the grid current changes, up to PF=0.99 in 15ms

Static Var Generator (SVG)— Three Phase (3)

Two-way compensation

SVG can realize bidirectional compensation of inductive reactive power and capacitive reactive power

System topology

01

Reactive power in power system is monitored by CT sensor

02

SVG device responds in real time and accurately outputs compensation current

03

The power system achieves PF=0.99

System topology

Dynamic stepless compensation

Can achieve a better compensation effect, there will be no over-repair and under-repair
