Abstract

This project is carried out to study on the performance of combination of series active power filter and shunt passive power filter for harmonic compensation through simulation. Two different control methods which are instantaneous active and reactive power (p-q method) and instantaneous active and reactive current component (id-iq method) are applied to the combined filter and the comparative study of their performance is carried out. The simulation is carried out using MATLAB Simulink- SimPower System block and a model of a complete network with a thyristor converter driven load was developed. The model was simulated in several phases; without any of the filter operating on it, with shunt passive filter acting alone, with a series active filter acting alone and with combination of both filters in order to examine the role of each filter involved. For each of the simulation, the THD of input line current is used as a performance measure. The studies had shown that the series active filter have a small effect in compensating the harmonic current while the shunt passive filter had a more significant role to compensate the harmonic current. The combination of both filters had enhanced significantly the ability of the filter to compensate the harmonic current. The simulation of the combined filter is extended by applying the two different control methods with three different conditions of supply voltage; a balanced and sinusoidal, unbalanced and sinusoidal and balanced and non-sinusoidal voltage. From the analysis of the harmonic content in the input line current (THD), it can be stated that under balanced and sinusoidal supply, p-q method and id-iq method have the same performance in compensating the harmonic. Nevertheless, under unbalanced and non-sinusoidal supply, the id-iq method had given a slightly better performance for harmonic compensation. Despite this slightly better performance of id-iq method, it can be conclude that it does not have much significant impact for the combination of series active filter and shunt passive filter in compensating the harmonic.
