| Abstract: | A new DC deicer system with 12-pulse mode and 5000 A rated current is developed. According to the parameters of AC transmission lines, some of its important aspects of PCS-9590 are introduced, including deicing solution, main circuit design, overvoltage and insulation coordination, control and protection system. Field application shows that the proposed DC deicer is an effective solution for the ice-clad problem of AC lines. |
