Reactive & harmonic control

Dynamic control of capacitor banks and active filters, with reactive compensation simulation and load balancing across phases.

Dynamic reactive power control

The Dynamic Reactive Power Control module supervises and dynamically manages the plant's reactive power. Its distinguishing feature is that it accounts for the available capacity of every capacitor bank in the system as a whole: from the configured rules and the measured electrical conditions, the platform analyses the network and determines the most appropriate connection or disconnection.

Decisions serve both the target power factor and the safety conditions of the banks and the network itself.

  • Auto ON — automatic operation through periodic analysis cycles.
  • Run now — runs an immediate cycle: reads the connection point, evaluates power factor and analyses distributed compensation capacity.
  • Settings — target power factor, operating tolerances, connection and disconnection rules, enabled banks, transformer loading limits, safety conditions and minimum time between switching operations.
Automatic operation should be enabled only once banks, communication devices and control permissions have been correctly configured and validated.
Traceability: every manoeuvre is recorded in the command history — time, origin, target power factor, ΔkVAr and whether it actually executed — so what was commanded, when and with what result can always be reconstructed.

Dynamic harmonic current control

The Dynamic Harmonic Current Control module supervises current harmonic distortion and manages the active filters installed across the electrical infrastructure.

It concentrates measurements of harmonic distortion, current unbalance, reactive power and available filter capacity. From that it identifies the points most in need of compensation and sets the target THD value the associated controllers are to use.

The Active Filter Banks section gathers active filter information by measurement point, with capacity and availability.

With automatic mode enabled, the platform evaluates available measurements, filter capacity and configured limits before determining any control action.
