| Abstract | In recent years, power quality becomes more critical because of the increase in the
number of loads sensitive to power disturbances, and as the loads themselves have become
major causes of the degradation of power quality. Therefore, power quality responsibility lies
with three main groups: the utility company, the customer group, and the manufacturing group.
A number of load types used in industries cause harmonic current and voltage
fluctuation such as electric arc furnaces (EAFs) that are found in Steel Manufacturing Facility.
Due to the arc furnace load, the significant voltage distortion will occur in power system,
which effects the other customer in the same area. In the utility side, the system configuration
also causes voltage distortion too. Simulation results from HI_ WA VE program show that the
fifth harmonic resonance occurs in power system and by changing the configuration of
capacitor bank at distribution feeders can solve this problem.
Electric arc furnaces cause voltage fluctuation on account of the oscillated of reactive
power. The field measurements illustrate the effect of this voltage fluctuation on another
customers in the same distribution area. Consequencely, by adding the static VAR
compensator at the steel manufacturing can reduced the flicker problem, which can be seen by
the simulation results of EMTDC program. |
