RS485/Ethernet communication optional SNA-SVG is a static reactive power generator (SVG) designed to compensate for reactive energy consumed or generated in real-time by inductive or capacitive loads.

It's the ideal solution for power factor correction in applications where the load varies rapidly (such as resistance welding, arc furnaces, refrigeration or compressed air compressors, etc.

) or in networks heavily polluted by harmonics.

It is designed with state-of-the-art technology based on high-performance IGBTs under a 3-level topology, it acquires the current signal of the load by the CT, the DSP tracks the command current in quick than calculate the reactive power rate of change by intelligent algorithm as to send the data to the IGBT by PWM signal.

Finally the inductive or conductive power compensation current is generated on the inverter to achieve the real-time dynamic reactive power compensation.

In addition to improving power factor, it provides energy quality solutions such as harmonic elimination and load balancing.

● Harmonic compensation up to the 51th order

● Load balancing between phases and neutral

● Compact design, three-level topology

● Expandable up to 12 modules in parallel

● Silent operation ≤65dB(A)

● RS485/Ethernet communication optional Special compensation for large loads: SVG is particularly suitable for special compensation of large loads, such as rolling mills, electric arc furnaces, and electrified railway traction stations in steel production.

These devices consume a lot of energy and have a significant impact and adverse effects on the power grid.

SVG can quickly respond and dynamically compensate for the reactive power required by these loads, thereby improving power factor and optimizing power quality.

Large industrial users: High energy consuming industrial loads, such as metallurgy, petrochemicals, etc., usually form their own power systems and are interconnected with the public power grid.

The power supply department has technical constraints on these users, especially power factor.

The application of SVG can help these large industrial users improve power factor, reduce electricity expenses, and improve the power quality of the grid.

Substation of power system: With the expansion of power grid scale and the complexity of network structure, the demand for dynamic reactive power compensation with fast response in substations has increased.

SVG can quickly absorb or emit the required reactive power, improve the transmission capacity and stability of substations, and ensure the safe operation of the power grid.

Hybrid compensation of harmonics and reactive power: Many large capacity industrial loads require both reactive power compensation to improve power factor and harmonic control.

SVG can not only dynamically compensate for reactive power of loads, but also simultaneously control harmonics, improve the power quality of the power grid, and enhance equipment operating efficiency.
