Abstract
Electric Arc Furnaces (EAF) are highly nonlinear load which causes power quality problems. Their nonlinearity and time varying characteristics generate harmonic distortion and voltage fluctuation. These effects are very harmful for the electric power supplying line and for other consumers. Utilities are concerned about these effects and try to take precautions to minimize them. In this project, an arc furnace model is developed and implemented. The main objective is to compare the performance of sinusoidal PWM voltage source converter based D-STATCOM control and SVC control for mitigation of voltage flicker caused by EAF. It is clear that STATCOM control has shown improved performance than SVC control. Moreover, the modeling and simulation of an IEC flicker meter are also performed to evaluate the severity of fluctuations in the simulated arc furnace voltage. Simulation and analysis are carried out in PSCAD/EMTDC environment. The reliability and robustness of the control scheme in the system response to the voltage disturbances due to EAF is obviously proved in the simulation results.
