li licheng, tsinghua university's eea1967 friend, chairman of the expert committee of china southern power grid corporation, a well-known power grid engineering expert and dc transmission expert in china, is reputed as "china's first person in dc transmission". this article has been transferred from the article "south net 50hz" in wechat official account. the original title: highlight time | south net experts rated as china's science and technology innovation figures!
the uhvdc transmission project is equivalent to a super aircraft carrier for power transmission,
with a transmission capacity of 2-3 times that of uhvdc.
at present,
one third of the electricity consumption in the yangtze river delta and pearl river delta regions in china is sent from the west,
most of which is completed by uhvdc.
if there were no uhv transmission technology to deliver clean energy,
the blue sky in the yangtze river delta and pearl river delta regions might not be as much as it is now.
uhv 800 kv dc transmission technology is the core technology for implementing the national strategy of "west-to-east transmission", which is inseparable from li licheng, known as"china's first person in dc transmission".
uhvdc transmission meets highlights again
experts from china southern power grid appraised
science and technology innovation person of 2018
on january 27, jointly sponsored by china media group and the chinese academy of sciences, and jointly sponsored by the ministry of science and technology, cctv-10 and bureau of science communication, chinese academy of sciences hosted the "science and technology ceremony-2018 science and technology innovation figures award ceremony" which was broadcast on cctv. as one of the top 10 science and technology innovation figures in the country, li licheng , chairman of the expert committee of china southern power grid corporation, appeared at the ceremony together with the company's scientific research team.

as well as the company's scientific research team's appearance, the gas field is 2.8 meters!
is little hertz call cheer south net! !
uhvdc transmission technologyfrom china's creation to china's leading
scientific and technological innovation supports "green mountain and green water" and "china's first dc transmission person". li licheng has been fighting with electricity for more than 50 years, finding ways to protect the environment with science and technology in breakthroughs!
more than 80% of china's energy is distributed in the western and northern regions, and more than 70% of its electricity consumption is concentrated in the eastern and central regions. the "west-to-east power transmission" has become a major strategy to optimize the allocation of energy and electricity across regions. because uhv can fundamentally solve the problem of large-capacity long-distance power transmission, under this background, li licheng proposed for the first time to develop high-capacity and low-loss uhv 800 kv dc transmission technology.
however, it is precisely because this technology is the first in the world and there is no experience at home and abroad to draw lessons from, and even has been questioned by the industry at home and abroad. "just because there is no foreign country, we cannot and dare not do it!” faced with a series of major challenges and difficulties, li licheng led the team to explore boldly and study with great concentration, often working late into the night. under the leadership and promotion of li licheng , the team has overcome one difficult problem after another in uhvdc transmission technology.
in 2010, the world's first ultra-high voltage project, yunguang ultra-high voltage direct current project, was completed and put into operation, creating 32 world's first projects! it also marks china's full mastery of uhvdc transmission technology. since then, well-known multinational power companies have gradually faded out of china's high voltage and ultra-high voltage dc markets. uhv 卤800 kv dc transmission technology provides a super solution to the problem of reverse distribution of energy and power load in china!
(the ±800 kv uhvdc transmission project from northwest yunnan to shenzhen in guangdong of the southern power grid is china's construction of the world's highest elevation uhvdc transmission project with the highest level of fortification and earthquake resistance. it can deliver 20 billion degrees of clean water and electricity in the west to the east each year, accounting for about 1/4 of shenzhen's annual electricity consumption. )
at present, china has completed 13 uhvdc transmission projects with a total transmission capacity of 98.6 million kilowatts, promoting large-scale intensive development and large-scale absorption of clean energy sources such as hydropower, wind power and solar energy in the west and north of china, and becoming the main channel of the "air pollution prevention action plan".
future dream is to challenge transparent power grid
taking the national strategic demand as its own duty, let the light of electricity illuminate all mankind.
after more than 50 years of hard work in the power industry, li licheng has presided over and participated in almost all oversize power transmission projects in china. for example, he has participated in and organized the construction of china's first 330kv ac power transmission project, the first 500kv ac power transmission project and the first 500 kv dc power transmission project. to participate in and organize the first ±800kv uhvdc transmission project in china and the world ...
on the scene of the award ceremony, li licheng , who was already waiting for honor, mentioned that he still had a dream ---
"some time ago, i focused on thinking about uhv flexible dc transmission, and now it has blossomed. so now my thoughts have jumped to the study of transparent power grid technology. transparent power grid technology will affect the ecology of the future power system and even the ecology of energy resources. it will have a subversive effect on the future development of the world and the future development of energy resources."
challenge the world's first disruptive power grid technology again!
li licheng said that confidence comes from ---
"we have a very good team, especially a group of young scientific and technological workers have grown up. i believe this dream and ideal will be realized."
breaking through foreign technological blockade,
from following to surpassing,
we will continue to explore hard and chew on "hard bones".
the power grid people cheered together.
climbing the new peak of energy and power technology again!
let the sky be bluer, the water clearer and the mountains greener.
