STATIC VAR GENERATOR(SVG)

The Static Var Generator features a modular design, with each module capable of independently or simultaneously compensating reactive power and harmonics. It exhibits strong control over voltage fluctuations and flicker, utilizing PWM interleaving technology to achieve extremely low self-generated harmonics and rapid response times of ≤2ms. With low power consumption and compact footprint, it increases grid capacity, reduces losses, and purifies the power grid.
Designed for a 20-year service life. Installation and commissioning are straightforward, with no wear-prone components and minimal maintenance requirements. The implementation of multiple PWM techniques, including multi-level and multi-phase equalization, significantly reduces carrier frequency harmonics in the compensation current. This represents the developmental direction for dynamic reactive power compensation devices.
