Serving the national energy strategy to climb the world's highest peak of HVDC transmission technology
After in-depth research and demonstration, State Grid Corporation decided to start ±1100 kV UHV DC operation. On January 26th, the company held a mobilization meeting in Beijing to fully deploy and mobilize the efforts to promote ±1100 kV UHV DC.
The meeting proposed that we should basically complete the key technology research in one and a half years, determine the main technical solutions of the project; break through the key equipment technical problems within two years, complete the model prototype development; build the ±1100 kV UHV DC demonstration project within 5 years.
Shu Yinlu, deputy general manager and member of the party group, attended the meeting and delivered a speech. Sun Hao, Assistant General Manager of the company, presided over the meeting.
As China's energy strategy moves westward, the country's development of energy resources in western regions such as Xinjiang and Tibet will further increase. These large energy bases are more than 2,400 kilometers away from the central and eastern load centers, and there is an urgent need to develop higher voltage direct current transmission technologies with higher voltage levels.
In 2009, State Grid Corporation fully launched the research on key technologies of UHV DC transmission technology of ±1000 kV and above. In 2010, the company organized relevant scientific research, design units and equipment manufacturers to conduct in-depth research and demonstration on UHV DC transmission technology of ±1000 kV and above, completed the concept design, and proposed a voltage level recommendation. On December 17, the company's party group held a special meeting to study and determine the voltage level of ±1100 kV.
Shu Yinbiao stressed that all relevant units should fully realize that the development of ±1100 kV UHV DC transmission technology has a good technical foundation, talent base and spiritual foundation; it is necessary to fully understand the difficulties in developing ±1100 kV UHV DC transmission technology, with emphasis. Do key technical research and key equipment development. He said that all units should scientifically and efficiently promote the work related to ±1100 kV UHV DC, set up a special organization as soon as possible according to the meeting requirements, implement responsibility, ensure resource input, and go all out to carry out work.
It is reported that ±1100 kV ultra-high voltage direct current transmission technology is the highest point of the world's high-voltage direct current transmission technology, and is the ultimate challenge of electrical technology and equipment manufacturing technology. The development and application of ±1100 kV high-voltage direct current transmission technology will drive the fundamental breakthrough in the development of electrical technology and the revolutionary innovation of equipment manufacturing technology, and comprehensively improve the ability of power grid allocation resources and the level of innovation in equipment manufacturing.
This meeting reviewed the important achievements of the company's UHV work, objectively analyzed the favorable conditions and major difficulties in the implementation of ±1100 kV UHV DC work, and elaborated on the significance of the development of ±1100 kV UHV DC transmission technology. The meeting requested relevant units to further strengthen leadership, increase investment, and spare no effort to promote scientific research, equipment research and development and engineering related work of ±1100 kV UHV DC transmission.
