Xuji Group hit more than 20 more of the "world's first" _ news

Is there a tool, an Arctic wind or solar energy resources and to the East near the equator, or weave a cross national boundaries, continents "energy Internet", resource-rich areas of the world clean energy super large-scale, global distribution of the Super-far-distance? Do not think that this is a fantasy, in late March, 2016 global Internet Conference was held successfully in Beijing marks the big idea of "operational" model officially open.


Global energy Internet, this "change the destiny of the human chess game" concept into reality, thanks largely to China's recent high voltage research and practice with great success. Xuji group, was standing in the international top of UHV high ground.


From "made in China" to "China wisdom"


When PM2.5, smog became a people's heart hurts, no one doubts that global energy for the whole country and even the Internet it means to be human.


But the distribution of energy in China, but has a natural obstacle to building energy Internet. 76% of China's coal resources are concentrated in North and North-West, 80% water resources concentrated in the Southwest, land new energy sources such as wind and solar power are also distributed in the Northwest, but 70% of the energy demand is concentrated in the East, 800-3000 from supply and demand.


Compared with the demand for energy resources and reverse distribution, power transmission capacity in China is more difficult to cross the natural moat. Nearly 30 years, 500,000-volt transmission system power transmission has been our backbone, but along with the rapid economic and social development, 500,000-volt transmission system faces a far distance and large capacity bottlenecks such as insufficient transmission capacity, corridor resources. No ultra high voltage transmission technology, Internet is a source of energy, a tree without roots.


UHV is the world's most advanced transmission technology, long-range, high capacity, low loss and less comprehensive advantages, is an international network on areas of "Everest". For a long time, its core technologies such as ultra high voltage valve, DC control and protection systems have been monopolized by ABB, Siemens, Alstom and other international giants.


Xuji group research and Development Director introduced Zhou Fengquan, a HVDC project, nearly half of the investment takes on the DC converter valve. The core technology is always a giant block of UHV power transmission technique "gate of life".


"Only two such Labs in the world at that time. Do a test to 2 million Yuan, while he purchased a product, will have to add a zero, 20 million Yuan! Spend money on technology, more is out there. "Zhou Fengquan said.


Markets reversed XJ Group Corporation embarked on the road of independent innovation, market competition and firm confidence in their independent research and development. 5 research and development personnel from 20 years ago started, XJ Group Corporation developed the DPS2000 DC control and protection systems, directly led to the price of similar foreign equipment "KS"; they have developed China's first UHV converter valve, 1/10 price of similar foreign devices.


With world-class technology, reliable quality and good brands, XJ Group Corporation, now all of the world's high voltage direct current transmission project provides 75% of "brain" (control systems), 50% "heart" (valve).


From "Chi" to "China"


The afternoon of May 11, is located in xuchang XJ XJ Avenue State grid group experimental study on ultra high voltage Engineering Center, a group of young people dressed in white overalls were doing ± 1.1 million volts high voltage control and protection system of simulation testing. Led the team DC transmission system in scientific research of the XJ group company General Manager Zhang proudly said: "there is world's highest voltage of equipment, has the world's most advanced technology, products with independent intellectual property rights, this is our core competence. ”


In special high pressure DC and Exchange transmission field, Xu following group has created has more than 40 more items "China first" and more than 20 more items "world first"--have Institute issued world Shang first sets ± 800,000 volts high pressure DC transmission for flow valve, world Shang voltage grade highest, and rated capacity maximum of ± 1.1 million v, and 5500 Ann special high pressure DC transmission for flow valve, built has world Shang integrated test capacity most strong of for flow valve run test system......


Since the second half of 2015, XJ Group Corporation with strong comprehensive strength, has bid less than 800,000 of State grid Corporation v North-Nanjing, Changji-± 1.1 million Volt guquan, Chongqing, Hubei, DC back to interconnection 19 uhvdc transmission projects.


Not long ago, Xilin GOL League to Taizhou ± 800,000 volts high voltage direct current transmission project the core equipment bidding, XJ Group Corporation "UHV converter valve" overall solution to beat two rivals, including the international well-known Enterprise, grabbed this cutting edge project.


"This shows that XJ has been leader in UHV converter valve in developed countries of the world. "Xuji group flexible transmission system company General Manager Zhang Jian said.


Ultra high voltage transmission technology, see China in the world. The Nobel Prize in Physics Laureate and United States Energy Secretary Chu, former Minister pointed out in a speech: "China challenges United States leadership in innovation related fields including: maximum voltage and highest transmission capacity of UHV AC transmission. ”


UHV projects has increased significantly in China in the field of international influence and voice, standard voltage UHV in China as an international standard. All this XJ Group Corporation credited. (Source: big river-Henan daily newspaper)

许继集团创下20多项“世界第一”_新闻资讯

  有没有一种技术手段,能将北极的风能或赤道附近的太阳能资源输送到我国的华东,或者织就一张跨越国界、洲界的“全球能源互联网”,将世界资源富集地区的清洁能源进行超大规模、超远距离的全球配送?不要以为这是天方夜谭,今年3月底,2016年全球能源互联网大会在北京成功举行,标志着这一宏大构想的“实战”模式正式开启。


  全球能源互联网,这一“改变人类命运的大棋局”能够由构想变成现实,主要得益于中国近年来在特高压研究与实践上的巨大成功。而许继集团,正是站在国际特高压制高点的顶尖企业。


  从“中国制造”到“中国智造”


  当PM2.5、雾霾成为国人的心头之痛时,没有人再怀疑全球能源互联网对于整个国家甚至人类的意义。


  但我国特殊的能源分布,对构建能源互联网却有着天然的阻碍。我国76%的煤炭资源集中在北部和西北部、80%的水能资源集中在西南部,陆地风能和太阳能等新能源也大量分布在西北部,但70%以上的能源需求集中在中东部,供需相距800—3000公里。


  与能源资源和需求的逆向分布相比,我国电力的输送能力是一道更难跨越的天堑。近30年来,500千伏输电系统一直是我国电力输送的骨干,但随着经济社会的快速发展,500千伏输电系统面临着远距离、大容量输送能力不足、走廊资源紧缺等瓶颈制约。没有特高压输电技术,能源互联网就是无源之水、无本之木。


  特高压是目前世界上最先进的输电技术,具有远距离、大容量、低损耗、少占地的综合优势,是国际上电网领域的“珠穆朗玛峰”。长期以来,其核心技术如特高压换流阀、直流控制与保护系统等一直被ABB、西门子、阿尔斯通等国际巨头垄断。


  许继集团研发中心主任周逢权介绍,一条直流工程,设备投资的近一半都要花费在直流换流阀上。这个核心技术,一直是国际巨头封锁特高压输电技术的“命门”。


  “当时世界上只有两个同类实验室。做一次试验就要200万元人民币,而购买他一个产品,还要再加个零,2000万元人民币!至于花钱买技术,更是门儿都没有。”周逢权说。


  市场倒逼许继集团走上了自主创新之路,市场竞争又坚定了他们自主研发的信心。从20年前的5名研发人员起步,许继集团成功研发的DPS2000直流控制与保护系统,直接导致国外同类设备价格“腰斩”;他们研制的我国首台特高压换流阀,价格仅为国外同类设备的1/10。


  凭着世界一流的技术、可靠的质量和良好的品牌,许继集团如今已为世界上所有的特高压直流输电工程提供了75%的“大脑”(控制系统)、50%的“心脏”(换流阀)。


  从“中国智造”到“中国引领”


  5月11日下午,在位于许昌市区许继大道的国家电网许继集团特高压工程试验研究中心,一群身着白色工作服的年轻人正在做±1100千伏特高压控制保护系统的仿真测试工作。率领这个团队科研攻关的许继集团直流输电系统公司总经理张爱玲自豪地说:“这里有全球电压等级最高的设备,有世界最先进的技术,有具备完全自主知识产权的产品,这就是我们的核心竞争力。”


  在特高压直流和交流输电领域,许继集团先后创造了40多项“中国第一”和20多项“世界第一”——相继研发出世界上第一套±800千伏特高压直流输电换流阀,世界上电压等级最高、额定容量最大的±1100千伏、5500安特高压直流输电换流阀,建成了世界上综合试验能力最强的换流阀运行试验系统……


  自2015年下半年以来,许继集团凭借雄厚的综合实力,先后中标国家电网公司±800千伏晋北—南京、±1100千伏昌吉—古泉、渝鄂直流背靠背联网工程等19个特高压直流输电重大工程。


  不久前,锡林郭勒盟至泰州±800千伏特高压直流输电工程进行核心设备的招标,许继集团的“特高压换流阀”总体解决方案击败包括国际某知名企业在内的两个竞争对手,夺下这项尖端工程。


  “这说明,许继在特高压换流阀领域已领先世界发达国家。”许继集团柔性输电系统公司总经理张建说。


  特高压输电技术,世界看中国。诺贝尔物理学奖获得者、美国能源部原部长朱棣文在一次演讲中指出:“中国挑战美国创新领导地位的相关领域包括:最高电压、最高输送容量的特高压交流输电。”


  特高压工程大幅提升中国在国际电工领域的影响力和话语权,中国特高压标准电压成为国际标准。这一切,许继集团功不可没。(来源:大河网-河南日报)
