Understanding SVG & APF

Core Analogy

Facing complex power quality issues? SVG and APF are the two core solutions. To understand them, just remember these two powerful analogies:

APF: The Grid's "Intelligent Scavenger"

Its Mission: To specifically "hunt" and "remove" harmonic pollutants.

How it Works: The APF continuously monitors the grid for harmonic "junk" and instantly generates a compensatory current that is "equal in magnitude but opposite in phase" to neutralize it. The result is a clean, smooth sinusoidal current flowing into the grid.

Core Value: Eliminates harmonic pollution, protects equipment, and saves on energy costs.

SVG: The Grid's "Super Stabilizer"

Its Mission: To dynamically "regulate" reactive power and stabilize system voltage.

How it Works: The SVG acts like an ultra-fast "smart reservoir." When system voltage is low, it instantly "releases" reactive power to boost it. When voltage is high, it quickly "absorbs" excess reactive power to reduce it.

Core Value: Stabilizes system voltage, avoids utility penalties, and improves power capacity.
