Zhang Zhengling, deputy director of the Planning and Development Department of State Grid Corporation of China, revealed that the first UHV DC project in Hunan Province - "Jiuquan" to the ± 800KV UHV DC line from Hunan to Jiuquan has been approved by the National Energy Administration. The project investment of about 27.6 billion yuan, higher than all existing and under construction UHV DC line, if it can start smoothly, will drastically pull China Western Electric Power Company performance. Zhang Zhengling told CCS China at the 2013 Beijing International Wind Energy Conference (CWP2013) on the 17th that the UHV DC project in Hunan has won "the trail of the National Energy Administration" and is expected to open the preparatory work for next year. An informed source told Great Wisdom News Agency today that Hunan UHV DC Project was allowed to carry out preliminary preparations and is expected to speed up the construction of Hunan UHV projects. At present, there are two UHVs planned and constructed in Hunan: the Mengxi-Changsha-Hunan Special UHV AC Project and the Jiuquan-Hunan UHV DC Project. According to CCS, Jiuquan-Hengyang UHVDC project is about 2,400 kilometers in length. The two new ± 800KV converter stations in Jiuquan and Hengyang and their corresponding grounding poles and grounding will be built via Gansu, Shaanxi, Chongqing, Hubei and Hunan. Pole line, transmission capacity of 8 million kilowatts, the project investment of about 27.6 billion yuan. Compared with all current UHV DC projects under construction and construction, Jiuquan-Hengyang Project involves the highest investment amount. Jiuquan into the Hunan UHV DC transmission distance longer project, the required investment is relatively large, mainly for Jiuquan two 8 million kilowatts of wind power sent and consumption. Hunan said the construction of this project will provide safe and clean energy for the rapid economic and social development in Hunan. Among the UHV DC projects in China, the investment in Xiangjiaba-Shanghai Line is about 18 billion yuan, the investment in Jinping-Sunan Line is about 22 billion yuan, the investment amount for constructing Hami South-Zhengzhou Line is about 23 billion yuan, and the Xiluodu-Zhejiang Line The investment is about 25 billion. National Development and Reform Commission approved only this year Zhebei - Fuzhou UHV AC Project started, no new line approved. State Grid said it will seek the approval of the start of Huainan - Nanjing - Shanghai, Ya'an - Wuhan two UHV exchange projects and Ningdong - Zhejiang UHVDC project. UHV line construction will boost the performance growth of a batch of equipment manufacturers. China Western Electric won the bid for Hami-Zhengzhou UHVDC project in 2012 with total equipment supply contract amounting to approximately 20.55 billion yuan, accounting for 16.46% of the company's revenue of that year. The successful products covered converter transformers , converter valves, GIS, capacitors, isolation Switches and other products, including 14 sets of high-end converter transformers. National media reported in August this year that the State Grid intends to invest 620 billion yuan to build a UHV power grid in the next five years. It is estimated that by 2020, UHV transmission power will reach 210 million kilowatts, which is three times the current 70 million kilowatts. In 2013, The investment in UHV is 52 billion yuan. Electric power equipment listed companies involved in UHV DC construction are listed as follows: Pinggao Electric, China West, Tianwei change, Xuji Electric, TBEA , Dalian Ceramics, Jinli Huadian.
