SVC Light for Steel Industries

Electrical Arc Furnaces (EAF) are the most common source of flicker. The violent forces released in the furnace process impose a wide band of disturbances on the power supply. This "electrical pollution" can be reduced by dynamic Reactive Power Compensation. However, these disturbances are not fixed. Rather, they are comprised of a mix of amplitudes and frequencies that change over time as a function of mechanical resonance, electrical supply, type of operation, and other process parameters. This wide variety of process parameters results in a behavior of a truly stochastic nature.

The only way to stabilize voltage and reduce disturbing flicker successfully is to continuously measure and compensate rapid changes by means of extremely fast reactive power compensation.

ABB has improved the reactive power compensation technology with special attention to severe voltage variations created by Electrical Arc Furnaces. The concept is named SVC Light®. With this new Light technology, response time is less than one millisecond.
