Power Quality Improvement Techniques

Bol

With increase in the level of the Technology, the use of electronic devices also increases. Itdeals with advantage of low power consumption, but injects harmonics in the power system and affects other sensitive loads. It causes increase in current and voltage amplitudes, heating losses, insulation failure and overall reduction in life span of devices. Thus, it affects the efficiencies of the equipments and the whole system. This is an undesirable effect. These Non-linear loads are main cause of harmonic injection in connected system. So, it should be eliminated from the system or, at least, reduced up to permissible limits. This projects deals with same problem of harmonics. The objective is to model and simulate a general system containing harmonics introduced due to non-linear load connected in the system and to mitigate this harmonics by using harmonic mitigation techniques, which result in power quality improvement. In this, the hybrid harmonic mitigation method is used. It aims to reduce harmonics accordingto IEEE harmonic limits.
