| Abstract: | When electric arc furnace is working,the high-order harmonic currents were produced and makes negative impact on the grid because of the reactive power fluctuations etc.It is found that the power filter is an effective method to improve power quality,however fast and accurate calculation of the required reactive current is the key to exact compensation.In this paper,we used MATLAB/Simulink to build the electrical system of three-phase EAF.Based on the instantaneous reactive power theory,the harmonic wave of three-phase electric arc furnace at PCC point was detected.The results show that the method is reliable. |
