Before the modernization of reactive power compensation, the facility operated two outdated automatic compensation systems, which only partially met the reactive power demand. The client’s main concern was frequent system failures. Detailed measurements showed that the reactive power demand was dynamic—without stabilization, with frequent transient spikes and sudden changes. The reactive power was inductive in nature, fluctuating between 50 and 170 kVAr.

Problem 

The existing equipment was outdated, prone to frequent failures, and no longer met performance expectations. All of this was reflected in the electricity bills.

Solution 

Considering the situation, it was decided to implement two innovative hybrid reactive power compensation systems designed for dynamic compensation. Two 200 kVAr hybrid systems were installed, each consisting of an automatic 2×50 kVAr stage and one 100 kVAr SVG. These solutions ensured fast and accurate reactive power compensation and reduced charges for reactive power.
