SVG (Static VAr Generator) Systems

In modern energy systems, the rapid and irregular changes in load characteristics, phase imbalances, and dynamic reactive power demands cause classical compensation methods to fall short in many applications. In particular, cranes, welding machines, rolling mills, frequently starting and stopping motors, and similar dynamic loads lead to sudden reactive power fluctuations and voltage variations in the system. In such applications, it is critically important that reactive power can be controlled not only in steps, but instantly, continuously, and with high precision.

SVG (Static VAr Generator) systems are advanced technology compensation solutions that can continuously adjust reactive power within milliseconds thanks to their power electronics-based structure. Operating in parallel with the grid, these systems instantly meet inductive or capacitive reactive power demand on demand.

The operating principle of SVG systems is based on continuously measuring the reactive power demand in the system and injecting a current of the opposite phase and desired magnitude in response. This ensures a fully dynamic and seamless compensation — unlike classical capacitor and reactor-based systems, which operate in steps.

Description

SVG systems:
  • Instantly adapt to sudden load changes with very fast response times,
  • Minimize imbalances by performing phase-based compensation,
  • Continuously maintain the power factor at the desired level,
  • Eliminate over-compensation and under-compensation problems,
  • Effectively reduce voltage fluctuations and flicker effects,
  • Do not create resonance risks,
  • Require no additional mechanical switching components,
  • Occupy less space thanks to their compact design.
  • SVG systems can optionally include a harmonic filtering function, contributing to the reduction of harmonic currents.
SVG systems are particularly preferred in:
  • Industrial facilities with dynamic and unbalanced loads,
  • Crane, welding machine, and rolling mill applications,
  • Production lines with automation and rapid load variations,
  • Sensitive processes where power quality is critical, delivering high-performance solutions.
During the design process, the system’s reactive power requirements, load variation speed, harmonic profile, and phase imbalances must be thoroughly analyzed. Incorrect capacity selection or insufficient analysis can directly impact system performance. Our company thoroughly analyzes your facility’s electrical structure and load characteristics to determine the most suitable SVG solution. Through the comprehensive engineering support we provide across all stages — including project design, product selection, on-site implementation, and commissioning — we guarantee that your system operates with maximum efficiency, stability, and reliability.
