Fast response

The SVGs in the SVGC show the advantage of the electronic power switch

Fast response is implemented by SVG modules.SVG reaction time <50us, complete response time <15ms; The SVGs in the SVGC show the advantage of the electronic power switch. In the legacy SVC, the thyristor only serves as a fast switch, but cannot implement high-frequency fast switching. (The frequency is typically 100ms, while IGBT in SVGs can switch more than 15,000 times in one second.)

  • Reaction time 33.4us

  • Reaction time<50us

  • Response time14.7ms

  • Response time<15ms

Excellent compensation performance

Traditional reactive compensation may cause over- or under-compensation.

Power components in the SVGC solution (SVG modules or LCs)


can be flexibly combined to realize:SVGC compensation between -1 and +1

Adjustable pricing of the SVGC solution

SVGC solutions for different industries

  SVGC Plan A SVGC Plan B SVGC Plan C
LC 50X5 50X4 30X9

Impressive Compensation Effect

SVGC and LC can be controlled by ICMS at the same time.


Compensation effect sequence diagram when LCs and SVGs are used together (LC-compensation capacity 30kvar, SVG- 100kvar)
100~200ms:

When the load' reactive rises sharply and LCs cannot respond promptly, SVGs will instantly respond and compensate the system reactive.

200~500ms:

When LCs start compensation, SVGs will instantly lower the compensation capacity.

900~1000ms:

When load's reactive slides sharply and LCs fail to reduce capacitors used, SVGs will instantly generate a reverse compensation reactive to offset the LCs' excessive capacitors.

1000ms~:

When LCs reduce the excessive compensation capacity, SVGs will instantly track changes to the system reactive and eliminate the residual reactive in the system.

了解ICMS

ICMS:Settle the operating mode and parameter of LC and SVG. Providing 18 I/O ports to implement flexible SVG+LC applications.

SVG:Prompt response to system reactive changes, and complete reactive compensation whenLC over-compensation or under-compensation to ensure PF=0.99

General LC:Compensating the load for most stable reactive with few changes
