| Abstract: | This paper discuses the technical scheme of the application of parallel single-core cables in one phase in 220 kV transmission line projects. The electromagnetic transient simulation software PSCAD/EMTDC is used to calculate the current distribution and the degree of unbalance in the parallel single-core cables, which 4 kinds of parallel cable arrangement are concerned. The best parallel cable arrangement which the degree of cur- rent unbalance is the lowest is recommended for project use. At the same time, GIS arrangement design in the substation, relay protection design and the power system communication setting are proposed for the 220 kV parallel single-core cable application. |
