High reliability, low losses

The modern way of compensation

Plant solutions / SVG – Power Controller

Advantages of the modern compensation systems

SVG is a new reactive power compensation solution based on 3-level IGBT technology. These compensation systems offer significant advantages over classic solutions with capacitors.

  • Compensation of inductive and capacitive reactive power

  • Stepless control

  • Low response times

  • Low weight: 100 kVar < 50 kg!

  • Very compact dimensions

  • No risk of resonance

  • No influence on ripple control signals

  • MTBF of up to 100,000 hours

Typical applications for a Static Var Generator:

  • Reactive current compensation in generator and UPS grids

  • Load balancing in commercial objects

  • Replacement of old compensation systems with capacitors

  • Dynamic control of reactive power

  • STATCOM applications such as in wind farms, PV plants and extensive cable grids

PQE MCQ – Master controller reactive power

Control software for power controller SVG

The PQE MCQ is a control software for compensation of inductive and capacitive reactive power. With a centralized measurement, e.g. at the transfer station of a grid, and a decentralized compensation, reactive power can be compensated and the shift factor cos phi can be improved. The software is executable on programmable Janitza UMG measuring instruments. PQE MCQ is designed for control and monitoring of dynamic power controllers SVG (Static Var Generator).

  • Control of decentralized compensations
  • Compliance with reactive power limits at the transfer station
  • Communication via modbus RTU
  • APP for all Janitza UMG PRO devices (except UMG 512)
  • Local main stations
  • Power stations
  • Energy supplier
  • PV systems
  • Wind turbines
  • Medium voltage applications
