Automatic reactive power compensation for key plant feeders.
Case study • Reactive power compensation
Installing a 415 kVAr compensation system
Kepno and Wieruszow – lower reactive energy charges and grid stability thanks to active harmonic filters.
We analysed power quality, selected the optimal compensation setup and integrated harmonic filters to protect production equipment.

Case study • Reactive power compensation
Project goal
Reduce reactive energy penalties and improve power quality with tailored compensation and harmonic filtering.
We designed a compensation system that stabilises transformers and safeguards production lines from voltage fluctuations.
Project footprint
- Kepno – main distribution switchboards
- Wieruszow – filter cabinets and protection systems
Scope of work
- Power quality analysis covering reactive load and harmonics.
- Selection and configuration of the 415 kVAr compensation system.
- Assembly and commissioning of compensation cabinets with harmonic filters.
- Integration of protections and control logic with existing infrastructure.
- Training plant personnel and launching online monitoring.

Challenges and solutions
Working within an active facility
The upgrade had to keep production running without disruptions.
Nivato solution
We executed installation during planned service windows with detailed safety procedures.
Reducing higher-order harmonics
Drives and converters introduced significant harmonic distortion.
Nivato solution
Active harmonic filters tuned to the load profile kept distortion within target limits.
Maintaining a stable power factor
Dynamic loads required continuously adjusted compensation.
Nivato solution
Automated control with live monitoring modulated capacitor stages as the load changed.
