In general, in order to solve the problem of low power factor of submerged arc furnace, China generally adopts the way of capacitance compensation, which is usually reactive power compensation at the high-voltage end. However, because the high-voltage end compensation can not solve the problem of three-phase balance, and because the inductive reactance of short network accounts for more than 70% of the inductive reactance of the whole system
