Static Var Generator(SVG)



 Product overview:

Static Var Generator, abbreviated as SVG. Also known as dynamic reactive power compensation generator, or static synchronous compensator. A self-commutating power semiconductor bridge converter is used to compensate dynamic reactive power.



SVG Working Principle:

Norya series Static Var Generator through the external current transformer, monitoring load current in real time, and through the internal DSP calculation to analyze the reactive content  of load current. Then according to the set value to control the PWM signal, which sends control signal to the internal IGBT so that the inverter produces reactive power compensation current to meet the requirements to achieve the purpose of dynamic reactive power compensation.

SVG Product Features


Traditional reactive power compensation is prone to over or under compensation.

In SVGC, SVC performs stage-level switching compensation.

SVG module performs blind spot coverage to realize stepless switching.

Users can flexibly configure the SVG module and SVC according to the requirements, and realize the application advantages in different aspects
Performance advantage: SVG enables SVGC compensation range from -1~1 to compensate for blind spot coverage simultaneously
Optimize the investment recovery: According to different compensation needs to customize different product mix, to achieve the best investment recovery
Expand the coverage of the application industry: Compared with the pure SVC, it can be applied to the occasions that the load reactive power rapidly changes so that the application industry is expanded 

The benefits of managing power quality:

Governance of reactive power

To reduce the cost of enterprise electricity;

To improve the power factor and avoid fines from the power sector;

To reduce line loss and occupancy of the upper level transformer capacity;

To reduce the loss of active power and voltage drop, release the transformer and generator capacity.
