What is a Static Var Generator?
SVG is an electronic compensation system that dynamically meets the reactive power demand (inductive or capacitive) in the grid. Operating with IGBT technology, the SVG works at millisecond speeds and continuously, unlike traditional capacitor banks. It keeps the Cos φ value consistently close to 1.
What are the operating principles of an SVG?
- The grid voltage and load current are continuously monitored .
- If a deviation from the power factor target is detected, the system immediately generates the appropriate amount of reactive power.
- It provides inductive or capacitive power as needed.
- The three phases are controlled independently.
- Response time ≤ 10 ms
- It does not generate transient currents, making it safe and capable of operating in parallel with generators.
How does SVG work?
Continuously operating electronic control system:
- Detects reactive power imbalance in the grid
- If necessary, corrects the cos φ value by injecting the appropriate current via IGBTs
- Since it operates continuously, there are no “on/off” pulses as in conventional systems
- Since control is achieved through voltage, it is fast and quiet
