CN-SVG Low-Voltage Static Var Generator (SVG) | Static Var Generator (SVG)

Feature

Continuous, dynamic compensation of reactive power: the device can compensate both inductive reactive power and capacitive reactive power, which overcomes the weakness of switching capacitor energy supplement, dynamic compensation and compensation capacity affected by the access voltage, and better achieves the purpose of reducing loss and saving energy.

Suppression of current harmonics: The device has a certain harmonic filtering ability, while providing dynamic reactive power, the remaining capacity can effectively suppress the 2~13th harmonics in the load current, and play a role in clean power energy and power pollution control.

Reduced voltage dip: Fast response to grid changes, 1ms response to load changes. It can solve the voltage drop caused by the frequent violet start of large impact load equipment, and can effectively reduce the voltage drop caused by the failure of the external power grid.

Three-phase balance of compensation load: The three-phase power is redistributed, so that the compensated load combination presents symmetrical balance load characteristics, reduces neutral current, reduces loss, and avoids accidents that may be caused by three-phase unbalance.

The closed-loop control algorithm can automatically avoid system resonance and improve the compensation accuracy: the device has an energy-saving mode, which adjusts the operation status of the switch according to different working conditions, and the efficiency can be as high as 99% or more, improving the safety of the device.

There are two types of products, screen cabinet type and rack type, which can be selected according to different use environments.
