The State-owned corporation, with 2.5 billion yuan ($301 million) worth of operating capital raised by the government, will be responsible for investment. construction and management of the power transmission and substation projects involved in the construction of the Three Gorges Project.展开更多

文摘Foreword Since the foundation of P.R.C.,the China's power grid develops with a high rate.By now,grids in all provinces except Xinjiang,Tibet,Hainan and Taiwan are AC/DC interconnected together,forming the structure of power grid interconnection in the whole country.
文摘In China,the primary energy bases and the energyrequirement areas are mismatched,which presents theremote and reverse distribution characteristics,and thelarge-scale power flow is from the west to the cast andfrom the north to the south.In this paper,according tothe above characteristics and the power flow pattern,thelarge-scale,high-efficiency and long-distance UHVACand UHVDC combined transmission scheme is investi-gated and proposed,and the development mode ofChina's power grid and the planning scheme of‘NorthChina-Central China-East China'synchronous UHV gridwhich can satisfy the healthy and sustainabledevelopment of China's economy and society is proposedand optimized.
