sir,
can i know from which site do i search about the topic harmonic compensation technique. I am not getting any material based on this topic and i basically have no idea about this topic.

An increasing number of harmonic mitigation techniques are available, including active and passive methods, and selecting the most appropriate technique for a particular case can be a complicated decision-making process. The performance of some of these techniques depends to a large extent on system conditions, while others require extensive system analysis to prevent resonance and condenser failure problems. In this paper we present a classification of the various harmonic mitigation techniques available to present a review of harmonic mitigation methods to researchers, designers and engineers dealing with energy distribution systems.


The nonlinear characteristics of many industrial and commercial loads such as power converters, fluorescent lamps, computers, light dimmers and variable speed drives (VSDs) used in conjunction with industrial pumps, fans and compressors and also in air conditioning Harmonic distortion is a common occurrence in electrical networks. The harmonic currents injected by some of these loads are generally too small to cause significant distortion in the distribution networks. However, when operated in large quantities, the cumulative effect has the capacity to cause severe levels of harmonic distortion. They do not usually alter end-user electronics such as overloading neutral conductors and transformers and, in general, cause additional losses and reduced power factor.
