The purpose of this ETAP Tutorial is to show how to size a shunt passive harmonic filter using the Harmonics Module. It illustrates the advantage of using the ETAP software to improve the speed and accuracy in conducting the power quality study needed to determine the appropriate capacitor and reactor ratings. This is made easy with the help of the Harmonic Filter editor, which provides all the practical and popular filter structures for the user to choose from.
In addition, listed below are the key features of ETAP’s Harmonic Filter and Sizing:
- Harmonic filter design and sizing
- Designing single-tuned, high-pass and band-pass passive harmonic filters
- Harmonic filter sizing based on power factor correction, minimum cost or minimum operation objectives
- Automatic harmonic filter overloading checking and alert
Harmonic Filters
As a review, harmonic filters are widely used to mitigate harmonic problems. A properly sized harmonic filter offers a low impedance path at the tuned frequency to eliminate a parallel resonance, such as the target harmonic frequency. It can also prevent the harmonic current from injecting into the system so that other electrical equipment won’t be affected by the negative effects of harmonics. However, installing the inappropriate inductor and capacitor ratings could possibly result to the harmonic resonance and amplification of the problems.
After finishing this ETAP Tutorial, one should be able to familiarize the basic steps in designing and sizing a passive harmonic filter using ETAP.
