SASTI-HPFC Hybrid Power Factor Correction
The SASTI-HPFC6MU series offers Hybrid Power Factor Correction system that combines the Advanced Static Var Generator (ASVG) with switching capacitors/reactors. Designed for flexibility and cost-effectiveness, it allows customized compensation schemes based on site-specific needs. Each component is modular, compact, and low-cost, ensuring the optimal balance between performance and price. This setup provides tailored solutions for superior reactive power compensation.
The SASTI system combines a thyristor switched capacitor (TSC) with a SASTI-SVG static var generator to improve voltage regulation, stability, and power factor in AC transmission and distribution. The TSC offers large capacity VAR compensation in steps, while the SASTI-SVG continuously compensates small capacity reactive power and filters harmonics from nonlinear loads, ensuring efficient and reliable reactive power management.
The SASTI-SVG may oscillate with traditional harmonic compensation if it doesn't account for TSC interaction. To fix this, a selective harmonic compensation method and a predictive control algorithm for TSC are used. This ensures accurate compensation during rapid load changes, providing continuous and cost-effective reactive power and harmonic current compensation.
