Techniques for power quality improvement by mitigation of harmonics

With the development in power electronic field, the use of non-linear electronic devices become popular. The main development can be seen in industrial and commercial sector in terms of low power consumption and more controllable process and management. But with these advantages, it causes to introduce harmonics in system. That's why; this paper focuses on the general system having harmonics due to non-linear loads and uses Tuned filter with Isolation transformer as Hybrid solution. This paper presents a simulation model with the different types of Tuned filters for mitigation of harmonics introduced in system due to presence of Non-linear load and also, a comparison is done in between various types of tuned filter as harmonic mitigation technique. The use of non-linear loads increases with increase in the technology level. It injects the harmonic contents in system. Thus, these injected harmonics can affect other connected system, that's why it should be eliminated or reduced at least up to permissible limits.
