High voltage vacuum circuit breaker Huayi Electrical equipment manufacturers, the only independent master of all the transformer core technology Tianwei change security gains across the board such as stock market trends, the next few days, several other power transmission equipment manufacturing companies shares are have soared. Industry insiders believe that this is because the State Grid Corporation issued a “second five” UHV during the development plan, huge investment will benefit equipment manufacturers.

“Eleventh Five-Year” period, with Jindongnan – Nanyang – Jingmen 1000 kV UHV AC pilot project, Xiangjiaba – Shanghai ± 800 kV HVDC transmission demonstration project put into operation, power transmission equipment manufacturing enterprises in China R & D capabilities and manufacturing capacity has increased significantly. China Machinery Industry Federation, the Office of major equipment, call Shuqing told reporters before the Commissioner, on the status of domestic electrical equipment and high voltage AC and DC played the role of demonstration projects were reviewed.

UHV equipment at home is a major driving force

Reporter: “Eleventh Five-Year” period, China’s major power transmission equipment in China, how?

Hu Shuqing: Since 2006, domestic electrical equipment, technical performance level has improved greatly, many of the major products reach the international advanced, some of the products reach the international advanced level. Particularly in power generation equipment, power transmission equipment development, the result was outstanding.

In the field of power transmission equipment, with the large number of key transmission project construction, equipment manufacturing enterprises and domestic technology capabilities has been increasing. Currently, 500 kV, 750 kV EHV transmission and distribution equipment has been fully achieved domestically, 1000 kV high voltage power transmission equipment is also essential to achieve the goal of domestic, ± 800 kV converter transformer manufacturing technology has been mastered, high-capacity SCR has been able to independently research and development, the domestic power transmission equipment manufacturing industry and the overall quality of the technical level can be increased dramatically.

For example, China’s first UHV 1100 kV step-up transformer rated voltage, rated capacity of 120 million kVA three-phase, directly to million-kilowatt generator set output voltage of 1100 kV rose from 27 kV to reduce power plant access to the middle part of the grid. Excellent indicator of the equipment, performance, stability, and represents the highest international level of similar equipment.

Reporter: the power to promote the localization of equipment what?

Hu Shuqing: In just a few years, technological level of China’s major power transmission equipment can be made great progress, can not do without the great support of national policy, and demonstration project of UHV AC and DC equipment for domestic use. Both the development of special high-voltage technology, or development of domestic high voltage equipment, national authorities have issued a series of supporting policies to support it.

The development of our government UHV transmission technology to improve the equipment localization rate has been very seriously. The State Council will study the development of UHV power transmission technology and equipment included in the “Long-term Scientific and Technological Development Plan (2006 ~ 2020)” and “speed up the revitalization of the State Council on Several Opinions of the equipment manufacturing industry” in order to enhance transmission and distribution the overall level of the equipment manufacturing industry and independent innovation capability, clear goals.

State Council also targets for major equipment, have introduced a series of supporting policies, a strong impetus to the special localization of high-voltage power transmission equipment. For example, the Ministry of Science and the “special high-voltage power transmission system development and demonstration” projects included in the “Eleventh Five-Year” National Technology Support Program; National Development and Reform Commission identified a 1000 kV UHV AC pilot project, and clearly the localization of objectives. National Development and Reform Commission also undertake development tasks of the key enterprises in upgrading equipment research and development, testing conditions and the ability of domestic work and other aspects of technological innovation, the industrialization of major equipment included in the special, which greatly advanced UHV power transmission equipment localization process.

Power transmission equipment upgrades necessary to use combined Education and Research

Reporter: UHV AC and DC demonstration projects is how to promote the localization of the major power transmission equipment?

Hu Shuqing: the support of relevant state policies, China’s special high-voltage DC equipment demonstration projects adhere to safe, reliable, advanced and national key enterprises for the core technology to master the principles.

These principles in practice in the construction have been implemented. To Jindongnan – Nanyang – Jingmen 1000 kV UHV AC works, for example, the project’s overall equipment localization rate of 90%, more than the original provisions of the State Development and Reform Commission 70% target. By participating in the project, the Western Electric Group, TBEA, Tianwei change security and other domestic enterprises to master the development of UHV transformer technology, Nantong Shenma mastered the development of composite insulators UHV technology, the high level of switching technology has been enhanced XJ Group, the Quartet following the security protection technology and other enterprises has reached the international advanced level.

UHV project through the construction of the initial realization of the domestic manufacturers of effective integration of different manufacturing techniques and upgrading to the key materials to achieve self into a symbol of power transmission equipment has been gradually changing the unfavorable situation of foreign constraints. China is in transition from a manufacturing power equipment, power equipment manufacturing, this is what we are looking for.

Reporter: Building UHV equipment made in China to promote technological progress, which we can derive inspiration?

Hu Shuqing: demonstration of UHV AC and DC power construction equipment manufacturing industry in China has had a profound impact, we gained important insight: Education and Research with the combination of equipment based on the project to promote domestic production, domestic equipment and technology to achieve an effective way to upgrade .

China is the only real UHV project running the country. With technology-intensive characteristics of power grid construction, in the absence of customer support cases, equipment manufacturers the prospect of the products developed will be difficult to predict. Users to organize inter-departmental and inter-unit, cross-industry joint research, to promote the domestic enterprises to participate in hundreds of high voltage electrical equipment, related equipment product development. Mutual benefit, complementarity and win-win cooperation mechanism, China’s national equipment manufacturing capability of independent innovation has been significantly improved.
