Utilizing MATLAB-SIMULINK Based Technique for Teaching Advantages of Harmonic Eliminating Using Shunt Active Power Under Steady State to Graduate Students

摘要

Harmonic current which is generated during connection of a non-linear load to system, if it multiplied by the network impedance it will distort the network voltage. This harmonic voltages and currents have undesirable effects, including the increase of dielectric losses and insulation stress, hysteresis losses, eddy-current losses, copper losses, overheating of transformers and cables, malfunction of system or plant components. In this paper description and definition of harmonics and their destroyer effects on power system is presented. Also the effect of harmonics mitigation using shunt active power filter under steady state is investigated. Due to educational purpose of this paper to teaching compensation advantages to graduate students the well-known software MATLAB-SIMULINK is used to simulate and investigate the effects of harmonics mitigation.
