Static Var Generator (SVG)
SVG Principle
The principle of the SVG is very similar to that of Active Power Filter, as demonstrated in the picture below.
Features And Benefits
Multifunctional: Reactive power, imbalance and part of Harmonic compensation
Excellent reactive compensation: High speed, Precise (-0.99 ≤ Cosφ ≤ 0.99), Step-less, Bi-directional (capacitive and inductance) compensation
Excellent imbalance correction: Both negative and zero sequence, mitigates neutral current
Harmonic Elimination Range: 2nd~25th order (Selectable)
Harmonic current capacity: 20% of rated current, 100 kvar SVG can output 30A H2-H25 harmonic compensation current
Wide input voltage & frequency range, adapts to tough electrical environment
Complete protection: Grid over/under voltage, SVG over current, over temperature, and others. All faults recorded in event log, convenient for failure analysis
