Ultra high voltage(UHV)transmission technology is a electric transmission technology with higher voltage rank than extra high voltage (EHV)transmission, it inludes UHV of alternating current transmission with nominal voltage equal to or higher than 1000 KV, and UHV of direct current transmission with nominal voltage equal to or higher than 600 KV. As for most electric networks in present China, UHV transmission means the electric transmission engineer and technologys being development with 1000(1050)KV altering current or ±800KV direct current. The advantage of UHV is that it can improve electric transmission ability by improving voltage rank. This paper analysis the running property of UHV system under steady state through editing Newton Raphson load flow calculational programme combined with UHV calculational cases.
