Power factor correction in presence of harmonics

In recent years, Power Factor Correction has evolved greatly due to the presence of generated harmonics by the loads. 

These loads produce harmonic currents and voltage which distorts the network waveforms. The main sources of harmonics are generated by AC/DC static converters and UPS systems. For these reasons it is essential that any installation of Power Factor Correction equipment must be carefully evaluated. 

The possible presence of harmonic currents in the network could create conditions of parallel resonance between the inductance of the network and the capacitors, generating overcurrents and overvoltages, which would cause premature failure of the power factor correction capacitors. The ideal power factor correction solution for any system must be determined by examination of the system parameters and harmonic spectrum.

Capacitor bank without regulation known as fixed compensation

Used when reactive power to compensate is constant and when the load is working 24h / 24h.

Used when reactive power is to compensate for low power. Also standardized by the coefficient QC (Compensation to install in KVAR) / SN (Transformer power in KVA) is generally <15%. This threshold of 15% is indicative and we recommend it to avoid to overcompensate the charge power vacuum.

Used to directly compensate the asynchronous motor, load losses of the line head transformer.

Static power factor correction capacitor

The reactive power regulator has a switching time of the banks extremely quicker than the standard regulator. The device for switching the capacitors banks is electronic, controlled by thyristors, with the capability of switching the capacitors at zero crossing. Maximum speed in switching the capacitors banks (the total power is switched in less than one second). No current peak on the capacitors at the time of switching of the banks. No voltage peak on the capacitors at the time of switching off the banks. Elimination of problems related to contactor contact wear.

Active filtering and power quality

FAFW is the new generation of active harmonic filters. It reliably mitigates harmonics and compensates voltage dips as well as reactive power. The FAFW analizes network disturbances and provides an opposing compensation current. In doing so, FAFW actively adapts to fluctuations and responds in less than half a millisecond. Its compact dimensions, simple installation, and digital intelligence allow for a quick and straight forward integration in the most diverse applications.

These products allows to reinject a current corresponding to the total harmonic component (the first order). By this way, the network is traversed by a current equal to the single fundamental component.

Fast test for maintenance

The “fast test” takes only 10-15 sec. According the discharge curve, the analyzer gives you a clear result of the battery status and save all results to the internal memory.

Monitoring software included

The monitoring software (for windows, linux and mac) gives you the informations about the battery.  You can export and print this report or simply save in the internal memory of the analyzer.

The OPZv batteries designed for long lifetime and have excellent deep cycle performance.
