Static Var Generator (SVG) Solutions
Optimizing Power Quality With Next-Generation Reactive Power Compensation
About Static Var Generator (SVG)
Our SVG units utilize voltage-source inverter technology to regulate reactive power instantly through precise control of AC-side voltage or current. This advanced design provides a substantial performance advantage over traditional compensation systems.
Static Var Generator (SVG) Features
Ultra-Fast Response
(<5 ms) Swift compensation for voltage fluctuations and flicker.
Stable Reactive Current
Maintains constant reactive current even during voltage dips, ensuring strong overload performance.
Enhanced Safety
IGBT-based current source design eliminates resonance risks.
Superior Harmonic Handling
Less affected by system harmonics; suppresses harmonics using multi-level or PWM technologies.
Compact Footprint
Occupies ½ to ⅔ less space than SVC, thanks to minimal component requirements.
High Reliability
Electronic control ensures stable operation with longer maintenance intervals.
How SVG Is Different From Conventional Capacitor Banks
SVG technology outperforms conventional capacitor banks by offering real-time, dynamic reactive power compensation with a response time of under 10 ms—far faster than mechanically switched capacitor banks. It requires no manual adjustment, delivers higher reliability, and significantly reduces maintenance needs. With a much smaller footprint and superior stability against load fluctuations, SVG provides an advanced, space-efficient, and future-ready solution for modern industrial power systems.
Applications Across Industries
OES has deployed four high-performance SVG systems across Pakistan, supporting a combined 32 MVar of reactive power compensation. These systems stabilize nearly 83 MW of industrial load and seamlessly integrate over 96 MW of renewable energy from wind and solar resources, significantly improving power quality, voltage stability, and grid reliability across cement, textile, and spinning industries.
Cement Industry
OES deploys SVG systems in cement plants to stabilize heavy industrial loads and eliminate voltage flicker caused by crushers and mills. The technology also ensures seamless integration of large-scale solar and wind energy.
Textile Industry
In textile units, OES uses SVG technology to deliver real-time reactive power compensation for spinning, weaving, and processing machines. This enhances power factor, prevents voltage dips, and supports hybrid renewable energy setups.
Yarn & Spinning Mills
OES installs SVG solutions in spinning mills to maintain voltage stability for high-speed motors and continuous operations. The system ensures efficiency and reliability even with significant wind energy integration.
