Catch a 10-fold increase in superconductivity in the smart grid express train for ten years

As the smart grid is written into the 'Twelfth Five-Year Plan', its status in the country's strategic emerging industries has gradually emerged. According to the relevant planning of the State Grid, from 2011 to 2015, the smart grid will enter the comprehensive construction phase in terms of transmission, transformation, distribution, and communications.

Globally, smart grids are also ushering in an investment boom. Among them, superconducting technology determines the competitiveness of a national smart grid to some extent. To this end, the United States proposed in the 'US grid 2030' plan to build a backbone grid using superconducting power technology. The U.S. Department of Energy even regarded superconducting as the only high-tech reserve for the 21st century power industry; the Japanese new energy development agency also believes that The development of superconductivity is the key to maintaining cutting-edge advantages in the 21st century.

According to relevant data from the international superconducting industry, the global superconducting power industry will have a production value of approximately US$7.5 billion in 2010. It is expected that by 2020, the output value will reach US$75 billion. In other words, the superconducting industry is expected to usher in the 'ten decade. Times' rapid growth.

The smart grid has entered the stage of comprehensive construction. After the smart grid is written into the 'Twelfth Five-Year Plan', the status of the smart grid in strategic emerging industries has been further enhanced. Su Bo, the vice minister of the Ministry of Industry and Information Technology, also expressed for the first time on 26th, supporting the development of a smart grid.

As the main provider of smart grid technology standards and key equipment, General Manager of State Power NARI, Ji Rui, said in an exclusive interview with the Shanghai Securities News reporter that the smart grid has risen to a national strategy and will become a smart grid investment during the 12th Five-Year Plan period. Development period. Among them, the huge application of superconductors in the power grid field has just begun.

The author learned from the State Grid that, from 2011 to 2015, the smart grid will enter a comprehensive construction phase, covering seven major investment areas: power generation, transmission, substation, distribution, electricity, dispatch, and communications.

The author learned from the State Grid Corporation of China that this year, as part of the '12th Five-Year' opening year, part of the smart grid investment will exceed 50 billion yuan, far exceeding the scale of less than 20 billion yuan last year. According to industry predictions, during the 12th Five-Year Plan period, China’s total investment in smart grid construction will approach 2 trillion yuan. This will greatly boost the demand for the products of major listed companies such as State Power NARI, XJ Electric and other listed companies.

It is worth noting that the vigorous promotion of relevant departments will further accelerate the industrialization of the smart grid. 'The smart grid can be effectively compatible with intermittent new energy sources such as wind power and solar energy, and can enhance the connection between the demand side and the supply side, and increase the efficiency of transmission and distribution. Therefore, China must strengthen the construction of a smart grid standard system and promote the development of key equipment for smart grids such as high-power energy storage and flexible transmission. 'Experts told reporters.

The “12th Five-Year Plan” outline is clear, it must adapt to the requirements of large-scale cross-regional transmission and new energy generation and grid connection, accelerate the construction of modern power grid system, further expand the scale of West-to-East power transmission, improve the regional backbone network, and develop high capacity such as UHV. , High-efficiency and long-distance advanced transmission technologies rely on advanced technologies such as information, control, and energy storage to promote the construction of smart grids, effectively strengthen the construction and transformation of urban and rural power grids, and enhance the ability of the grid to optimally configure electric power and reliability of power supply.

The outline also clearly stated that during the 12th Five-Year Plan period, pilot projects for smart grid construction should be carried out, smart substations should be reconstructed, smart meters should be promoted, and electric vehicle charging facilities should be built.

In fact, as early as the national energy work conference at the beginning of this year, the National Energy Administration clearly stated that in the future, it will transform the distribution network, actively promote the construction of smart grids, and improve the level of information, automation, and interaction of the grid.

According to Liu Zhenya, general manager of the State Grid Corporation of China, China has achieved a large number of achievements in the areas of theoretical research and experimental systems for smart grids, as well as access to clean energy, intelligent dispatching, smart substations, electric vehicle charging and replacement, and smart homes. At the world leading level. The 'Twelfth Five-Year Plan' will comprehensively implement the intelligent construction and transformation of power generation, transmission, substation, power distribution, electricity, and dispatch, and improve the safety, controllability, adaptability, and interaction of the power grid.

The process of industrialization of superconductivity is expected to accelerate. According to industry figures, superconductivity is a key technology in the process of large-scale construction of smart grids. If the price of the superconducting cable is attractive enough, it will enter the commercial application of the smart grid, and the prospects are very broad. To this end, Shanghai issued in May 2010 "Shanghai to promote smart grid industry development action plan (2010-2012)", clearly stated that superconducting current limiter is the focus of the development of smart grid industry in Shanghai.

In fact, superconductivity technology has a full 100-year history. In 1911, Kahleyn Onnes of the Leiden University in the Netherlands discovered that the resistance suddenly disappeared when the mercury was cooled to -268.98°C. Later, he discovered that many metals and alloys have similar characteristics. This discovery has attracted widespread attention. People call superconducting conductors 'superconductors'. Ultra-high voltage transmission has a large loss, while the use of superconductors can minimize losses. After years of technological development, superconductivity has now entered the stage of industrialization.

It is reported that superconductors include superconducting generators, superconducting transformers, superconducting cables, superconducting current limiters, and superconducting energy storage technologies.

The author recently learned from the State Grid Corporation of China that the world’s first 220KV superconducting current limiter project of Tianjing Power Company will soon be put into operation. This is the application of China’s superconducting industry to the power grid industry following the two major projects in Yunnan, Phuket, and Gansu and Baiyin. Another major breakthrough has meant that the superconducting industrialization process is accelerating.

It is understood that since the project was established in 2006 and started in 2007, after several years of equipment development, it has now successfully entered the stage of experimental operation. Currently involved in this project are the technical partner Yunnan Yingna Superconductor Corporation and the equipment side Tianjin Baili Electric.

In addition, the State Grid is preparing to build a 1 kilometer long and 110 kv high temperature superconducting cable demonstration project, which is planned to be completed in 2012. The construction and investment of the State Grid and China Southern Power Grid for superconducting pilot demonstration projects will greatly stimulate the development of the domestic superconducting equipment industry, and the huge investment prospects of the superconducting industry will thus emerge.

Dc Worm Gear Motor has very low efficiency, normally for the first stage, the efficiency will loss at least half. However, dc worm gear motor is widely applied on some products need with self-lock function. Like the automatic range hood in the kitchen, or the roller blind motor.
