Electric arc furnaces(EAF) is a kind of no-linear and strong time-varying load
which will cause many such power quality problems in the grid as voltage fluctuation and flicker
harmonics and low power factor.The compensation result of traditional SVC compensation device is limited due to slow response speed.SVG is the most effective device to solve the electric power quality problem of EAF
but the successful compensation of the SVG in the electric arc furnace in china is very rare due to complicated control algorithm.In this paper
the use of a 70 Mvar cascade SVG in an EAF site in China is introduced.It is shown by the site test data that the power quality has significant improvement after operation of SVG and fully reflects superior compensation performance of SVG for the load of EAF.
