Study on Voltage Fluctuation and Flicker Suppression of Electric Arc Furnace Based on Fault Current Limiter
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.
