      December 22-23rd, Hami, State grid Corporation of China held in Beijing-Zhengzhou ± 800,000 volts high voltage direct current transmission project (pre) preliminary design review. It is reported that that the Mayor of Zhengzhou, HVDC transmission project is the world's first ± 800,000 volts, transmission capacity of 8 million-kilowatt level of HVDC transmission project, line length of 2210.2 kilometers. Projects are put into operation in 2013, bipolar low-end, 2014 completed in the first half.

      Session a comprehensive and detailed review of the engineering design technology for converter station and lines plan to guide design and construction, is significant to realize sound and fast advance. And party member Zheng Baosen, Deputy General Manager of the company attended the meeting and delivered a speech.

      Zheng Baosen said, construction Hami-Zhengzhou DC transmission engineering, will Xinjiang Hami coal electric, and wind electric resources rushed to Henan load Center area, West resources advantage conversion into economic advantage, is implementation science development views and implementation "a special four" development strategy, go sustainable development road of major initiatives, for maintenance Xinjiang national area stability, and promoting "West big development", and "Central rise", regional development strategy of implementation has major meaning.

      Zheng Baosen stressed that the design works as a project leader, is to protect the project "safe, reliable, and independent innovation, environment-friendly and economical, world-class" quality fine works of the first link, you must attach, from sources designed to create high quality fine works. To seriously full summary design experience, continued optimization upgrade and promotion optimization results; in-depth implementation anti-accident measures, elimination security hidden; efforts implementation standardization design, improve engineering efficiency; focused on differences of design, adapted Northwest geographical features; strengthened design interface tie, ensure the work coordination unified; strictly control engineering cost, improve DC transmission economic sex, further increased transmission in energy conveying way in the of compared advantage.

      Hami-Zhengzhou HVDC transmission project is the world's first ± 800,000 volts, transmission capacity of 8 million-kilowatt level of HVDC transmission project, line length of 2210.2 kilometers. The project compared to the Su project, and upward, Kam, conveying larger capacity, transmission distance farther, confronted with more complicated environmental conditions, and technical requirements of safety and quality higher, the follow-up of uhvdc project with a demonstration and promotion role. Engineering feasibility study launched in late March, May make national development and Reform Commission at the end of flagging. The company has organized complete converter stations and lines of (pre) preliminary design, this review will be completed as soon as possible after the meeting follow-up studies and preliminary design techniques and close, accelerated construction design. Projects are put into operation in 2013, bipolar low-end, 2014 completed in the first half.

      China energy development Holdings Limited Vice General Manager just, Deputy Li Wenyi, Chief Engineer of the State grid Corporation, the State grid Corporation of China headquarters departments, provinces along the Northwest and central divisions, companies, design units and related units directly under the relevant personnel to attend the meeting.
