Electrical Arc Furnace (EAF) consumes time-varying power. This causes mechanical torque variations in nearby small scale synchronous generators (SSSGs) and reduces their life expectancy. In this paper, an appropriate EAF model is provided and is verified by field measurements. Moreover, an actual distribution system to which an SSSG is connected to supply industrial loads including an EAF is investigated based on time-domain simulation studies. Analytical and simulation-based studies are accomplished to determine proper SSSG controller parameters to mitigate the mechanical oscillations caused by EAF. In addition, SSSG transient performance is considered to appropriately adjust the controller parameters. Robustness and effectiveness of the proposed controller parameters are investigated using field measured EAF current signals. 
Keywords: Electrical Arc Furnace (EAF), generator torque variations, micro grid control, small scale synchronous generator (SSSG).
