TMEIC Dynamic VAR Compensation – Dyna-VAR™

Dynamic Reactive Power Control for Voltage Stability

The Dyna-VAR system is based on proven medium voltage PWM converter

technology and provides dynamic control of reactive power—both leading

and lagging. It improves voltage stability across the facility, minimizes

voltage dips, and reduces the risk of equipment trips and shutdowns due

to transients.

• Based on proven drive converter technology

• Dynamic control of leading and lagging reactive power

• Minimizes voltage dips due to high lagging VAR loads

• Stable voltage minimizes risk of equipment shutdowns
