Electronic compensation

Electronic compensation makes it possible to compensate inductive, capacitive and harmonic reactive power. Additionally, it is possible to rectify existing 3 phase load imbalance. This creates extra space for power, limits energy losses and prevents claims against malpractice and potential fines.

The reduction of harmonic currents significantly improves voltage quality, so connected equipment functions more efficiently, more effectively and improves longevity.

The Static VAR Generator (SVG) and Active Harmonic Filter (AHF) from Sinexcel are based on 3-level IGBT technology. This has resulted in lightweight, compact units suitable for either wall or rack mounting. Both models incorporate a user-friendly colour screen.

Static VAR Generator (SVG)

The successor to the cos phi bank

Historically, capacitor banks have been used in installations to reduce reactive current. In modern installations, these capacitor banks often cause problems with overheating an inefficient performance.

Where active harmonic filters are too expensive, we can provide an electronic variant of the capacitor bank - based on 3-level IBGT technology - the Static VAR Generator.

Working principle of an SVG

A Static VAR generator (SVG) is a fast electronic and stepless reactive current compensation without capacitors. The SVG measures the inductive current [1] and injects a current which is phase-shifted with the voltage [2] so that the current for the filter [3] flows neatly with the voltage.

Properties of a Static Var Generator

  • Compensates for both inductive and capacitive reactive power
  • Eliminate imbalance in phase currents and creates power space
  • Resistant to harmonic currents

Typical application areas of a Static VAR Generator

  • In capacitive networks where the emergency power generator does integrate correctly
  • To compensate for rapidly changing electronic loads
  • Installations with unbalanced, loaded phases where more power space is required
  • Eliminate imbalance in feed-in at solar parks

Advantages of SVG over a capacitor bank

  • Compensates for both inductive and capacitive reactive power
  • Super-fast response time (<20ms)
  • Fast and stepless, so that the possibility of over- or under compensation is removed
  • More compact and lighter weight
  • Reduced energy loss
  • Impervious to resonance and interharmonics and not overloadable
  • Maintenance free

Compensating for harmonic currents

With an active harmonic filter, harmonic currents can be compensated, creating additional power space and preventing machine and equipment failure and improving equipment longevity.

The active filter is based on 3-level IGBT technology, making the filter compact and minimising losses.

Working principle of an active harmonic filter (AHF)

An active harmonic filter, filters harmonic currents with an operating principle based on “noise canceling”. The filter measures the current pollution [1] and injects a counter current [2] which is shaped in a way that the current for the filter [3] becomes sinusoidal again. This compensates for all harmonic reactive power.

Inductive, capacitive and harmonic compensation

The harmonic filter is also able to compensate both inductive and capacitive reactive power, making such a filter universally applicable and not overloadable.

Properties of an active harmonic filter

  • Elimination of harmonic currents
  • Compensate for both inductive and capacitive reactive power
  • Eliminate imbalance in phase currents and create power space
  • Improve voltage quality

Advantages of an active harmonic filter

  • Super-fast response time (<5ms) and continuous adaptation to the load
  • Less losses, lower footprint
  • Not overloadable and impervious to resonance and interharmonics

Advanced Static VAR Generator

The best solution for reducing reactive power and filtering out the most common harmonics

In most installations the reactive power consists of inductive reactive power (poor cos phi) and harmonic reactive power caused by current harmonics up to the 9th order. The ASVG was developed precisely for this application.

As with the SVG, the ASVG can be used to reduce inductive or capacitive reactive power. In addition, 50% of available compensation capacity can be used to reduce harmonic through to the 11th order. This means that for most installations, the ASVG is the most effective solution for reducing reactive power.

As with the AHF and the SVG, the ASVG is based on IBGT technology. This results in a small product footprint, lightweight design and  reduced losses.
