Abstract

For solving the severe voltage fluctuations and flicker due to highly nonlinear load of the electric arc furnace

in this paper

a kind of device suppressing electric furnace voltage fluctuation and flicker based on fault current limiter is proposed for the first time. The device has such advantages as low operating loss

no need for control

and significant suppression effect. In this paper

the specific regulations for voltage fluctuations and flicker in China national standards for EAF is introduced at first. Then the basic principle of the fault current limiter and the working principle of the suppression device are described. The simulation model of EAF for voltage fluctuation and flicker analysis is given in accordance with the operation characteristics and arc characteristics of the actual EAF. Finally

the simulation result is analyzed and compared through the simulation and the both effectiveness and economy of the new device proposed in the paper is verified.
