PERFORMANCE ANALYSIS OF INSTANTANEOUS HARMONIC POWER THEORY BASED ACTIVE POWER FILTER UNDER DIFFERENT LOADING CONDITIONS
Journal Title: International Journal of Electrical and Electronics Engineering Research (IJEEER) - Year 2017, Vol 7, Issue 1
Abstract
In Distribution system the non-linear loads and use of power electronics based equipment’s are raised. Due to the increase of non-linear loads drawing non-sinusoidal currents and generate harmonic current at PCC, which may deteriorate the power quality. In distribution system this distortion has become a serious problem in electrical power systems. In this suggests a method that consists of 3-leg inverter i.e. capable of compensate current imbalance and harmonics presented in system. This setup named as Active power filter (APF) is shunted to inject power into System. The inverter is actively controlled in such a way that it draws/supplies fundamental active power from/to the Industrial loads. The effectiveness of the filter depends on its control strategy. This work instaneous harmonic power is used for compensation of harmonics. All of these functions may be accomplished either individually or simultaneously. Here the system is connected with industrial loads. Matlab/simulink based system setup is developed and performance of APF is showed at load is constant, increment in load and decrement in load conditions.
