Abstract :
Ideally, an electricity supply should invariably show a perfectly sinusoidal voltage signal at every customer location. However, for a number of reasons, utilities often find it hard to preserve such desirable conditions. The deviation of the voltage and Current waveforms from sinusoidal is expressed as harmonic distortion. The harmonic distortion in the power system is increasing with wide use of nonlinear loads. Thus, it is important to analyze and evaluate the various harmonic problems in the power system and introduce the appropriate solution techniques. A single-tuned filter design is illustrated and implemented in a model which created in Electromagnetic Transient Analysis Program (ETAP). The system was constructed for this simulation and does not represent one particular real life system Furthermore, the model was used to test the effects of injecting harmonic current by variable speed drive (VFD) into 3 situations. Firstly, the scheme with capacitor banks only, then, using a single-tuned filter and finally both schemes coherently.
