Nowadays,　the　power　demand　has　been　dramatically　rising　in　highly　populated　load　areas.　The　high-temperature　superconductor　(HTS)　cables　are　one　possible　solution　for　the　electricity　transmission　due　to　their　high　transmission　capacity　and　tremendously　lower　electrical　loss　compared　with　traditional　power　cables.　A　comprehensive　and　accurate　model　is　very　important　to　predict　the　working　condition　prediction　for　the　purpose　of　power　flow　control,　relay　protection　and　overvoltage　protection,　especially　for　HTS　cable　which　is　highly　expensive　and　lacking　of　operation　experience.　In　this　paper,　a　simplified　analytical　model　of　HTS　cable　is　presented　to　further　facilitate　operating　condition　simulations.　The　inductances　are　derived　and　the　result　is　verified　with　FEM　software　COMSOL.　The　self-,　mutual　inductances,　capacitances　between　each　layer　are　calculated　to　build　the　parameter　matrixes.　By　appropriate　transformation,　electrical　parameter　matrixes　can　be　converted　into　simplified　PI　sections.　A　simple　simulation　model　for　power　system　containing　HTS　cable　can　be　built　up　by　using　EMTP-ATP　program.　The　instructive　guide　for　protection　systems　for　HTS　cables　may　be　provided　according　to　the　simulation　results.　The　simplified　distributed　parameters　model　described　in　the　paper　is　also　helpful　for　structure　optimization　to　obtain　uniform　current　distribution　in　superconductor　layers.
