| Abstract: | The insulation coordination for converter station in ±800kV UHVDC project from Xiangjiaba to Shanghai is one of the key technologies of UHVDC project. The configuration scheme of lightning arrestor protection for converter station, the principle of insulation coordination and overvoltage protection strategy for converter station are analyzed; the parameters and characteristic of lightning arresters are calculated; after analyzing the overvoltage protection for equipments and insulation level of equipments in detail, the discharge voltage of air clearances in converter station is given preliminarily. These data for insulation coordination could be used to guide the selection and manufacturing of equipments for converter station. |
