Evaluation Analysis of First DC-Based Deicing Device in Northwest China |

| Abstract: | DC-based deicing devices which were put into operation in Longnan of Gansu province greatly enhanced the anti-icing capability in the area. The software Matlab was used to carry out simulation analysis for the model of 330kV Shaidu lines and to verify the test results of the current power quality. Meanwhile, the rectiifer was unloaded, the electric brake was turned on in the process of starting the equipment and the reason of protection mal-operation was analyzed rapidly. This paper gave the measures of lfashy lfow tripping operation, which effectively reduced the number of tripping of the switch in the transformer substation, shortened the outage time and improved the reliability of power sup-ply. |
