Static Var Generator (SVG)

The Static Var Generator (SVG) is suitable for voltage systems of 380V-660V and is an important component of Flexible AC Transmission Systems (FACTS). This device acts as a controllable reactive current source that can quickly respond to changes in load reactive power, automatically compensating for the reactive power required by the grid. This helps bring the system power factor close to 1, achieving voltage stability, energy savings, and ensuring the safety of the power system.

Feature
1

Dynamic reactive power compensation can simultaneously compensate for both inductive and capacitive reactive power, effectively reducing energy consumption and improving energy efficiency.

2

Harmonic suppression cleans the power and mitigates power pollution.

3

Reduction of voltage dips with a fast response time, adapting to load changes within 1 millisecond, effectively addressing voltage dips caused by large fluctuating loads, and minimizing the impact of external faults on the grid.

4

Redistribution of three-phase power achieves symmetrical balanced loads, reduces neutral current, minimizes losses, and prevents accidents caused by imbalance.

5

Closed-loop control algorithm provides high-precision compensation capabilities and can automatically avoid system resonance.

6

Available in cabinet-style and rack-mounted options, suitable for different installation environments.
