Yesterday, Guilin Aerospace Electronics Co., Ltd. in front of a lively and festive atmosphere. All the company’s cadres and staff members celebrated the success of the “Chang†with the flag raising ceremony and watching the Yangko performances. Originally, 85% of relays and other three types of relays on the Chang'e II and Long March III C carrier rockets were manufactured by Guilin.
"Guilin Build" Helps Flying Flying
On October 1, the second lunar probe independently developed by China, Chang'e 2, was successfully launched at 18:59:57 on the same day. At this moment, Guilin Aerospace, who is thousands of miles away, cheers for the tears.
“Chang'e II and carrier rockets have all the key components we have manufactured in Guilin, and some of them are also used in key areas.†Although Chang’e II has been successfully launched for a week, it was on the staff’s face during the celebration ceremony yesterday. Can not hide the joy of excitement.
It is understood that Guilin Aerospace Electronics Co., Ltd. established a plant in 1958 and entered the aerospace system in 1965. For more than 40 years, it has been responsible for the supporting tasks of two bombs, satellites, spacecraft, and launch vehicles. The company is only "Chang'e II" supporting relays, connectors, special switches three major categories of components, the number of products accounted for more than 85%. These relays act as power distribution, control, and transmission signals on lunar exploration ships, satellites, and rockets. Therefore, they run through ignition, navigation, telemetry, and landing. In other words, any relay is related to the safety of space exploration.
"Guilin made" again tested
There are tens of thousands of electromechanical components (components) on satellites and rockets. Even if one of them is a problem, the consequences are unimaginable. It puts unprecedented high-standard technical requirements on All Products.
“A year ago, we received the task of research and development of Chang'e II components.†The person in charge of the R&D center said that for the needs of the lunar exploration project, the company organized a think-tank to carry out technical research, through full justification and detailed calculations. Relevant parameters, then technical discussions, formulate a research project, and guide operators to carry out trial batch product assembly.
After the product is submitted, make a bottom test and follow-up test. According to the test results, carry out technical discussions and repeat the “design-assembly-test†several times to determine the product production plan. In the process of repeated trials, Guilin Spaceman paid a lot of hard work and sweat to provide highly reliable qualified relay products for the lunar exploration project.
"From "God One" to "Shenzhou Seven", from Chang'e 1 to the present Chang'e 2, the fact that each launch succeeds in using iron proves that the quality of relays and other components we built in Guilin is reliable and stable. "Guilin Aerospace Electronics Co., Ltd. leaders said so.
It is precisely because of this, Guilin space people participate in the design, production and testing of the components will be more and more, playing a more and more important role.
Seize smart grid international technical standards
In terms of smart grid technology standards, both domestic and foreign organizations are currently conducting standard research. The IEC organized the "Smart Grid Working Group (SG3)" to lead the research on smart grid standards. NIST released the "Smart Grid Interoperability Framework and Roadmap". In addition, the IEEE established the P2030 Working Group to work hard to prepare the "IEEE. P2030 draft standard, the European Standardization Organization CEN has established a working group to actively promote smart grid standard research work. The Ministry of Economy, Trade and Industry of Japan has established a smart grid standardization strategy working group.
The research field of smart grid standards in China began in 2009. In 2009, the State Grid Corporation of China initiated the research on the smart grid technology standard system and established an expert working group to carry out the work. Starting from the needs of the smart grid, the working group compiled and completed the “National Grid Smart Grid Technology Standard System Plan†based on eight professional branches, based on the 779 existing international standards and 772 domestic standards. Three-step planning and deployment of the standard system planning.
The above-mentioned technical standards of the State Grid Corporation of China are corporate standards, which cannot replace national standards and can not replace industry standards. This is a programmatic guide for corporate standards. Under the guidance of the relevant national ministries and commissions, the State Grid Corporation of China will use these enterprise standards as a system to speed up the preparation of smart grid enterprise standards, and actively participate in the formulation of industry standards and national standards, and carry out the internationalization of smart grid standards, it needs to be emphasized Now that the State Grid is doing business standards, and possibly national standards and industry standards have not yet come out, we must first strive to strive to become an international standard. Before the standard procedures were the first corporate standards, post-industry standards, and then national standards, and then see See if you can become an international standard. Now we must have such a mentality in the smart grid, that is, in the absence of national standards, industry standards, or even corporate standards, preemptively seize international standards.
In fact, there are no national standards in other countries. ABB, Siemens and other international multinational companies are heavily involved in the smart grid, and they are more likely to seize the standard of the smart grid. Once some standards are seized by these companies, they will invest a lot of money. The funds used for research and development, and China's first R & D, after the application, and then formulate the standard model is completely different, so the State Grid Corporation first to corporate standards as a foothold to actively support the development of national standards and industry standards, but also to seize international standards .
Judging from the level of the standard system, the national grid company smart grid technology standard system consists of eight professional branches, each professional branch is divided into several technical areas, a total of 26 technology areas, each technical field covers a number of standards The series consists of 92 standard series. Each standard series consists of several specific standards and is divided into 5 levels.
Judging from the progress of the current standard system planning, the “Technical Regulations on the Integration of Wind Farms into Grids†has been issued as an enterprise standard for smart power generation, and the “Technical Regulations for the Integration of Photovoltaic Power Plants into Power Grids†has been applied for. In terms of intelligent power transmission, “overhead transmission The general technical conditions of the line on-line detection system have been issued as the company's corporate standard, and six standards such as the "Technical Guidelines for On-line Monitoring System for Power Transmission and Transformation Equipment" will be completed in 2010. In terms of intelligent power transformation, "Technical Specifications for Intelligent Transformation of Substations" And so on, it has been released as an enterprise standard; in terms of smart power usage, the first 12 technical standards related to the “smarts†and the 24 technical standards related to the “electricity information collection system†have been released as corporate standards, and The five automotive-related standards have been issued as corporate standards.
At the same time as the grid companies formulate the standard system, the State Grid Corporation selected the technical standards that are closely related to the construction of smart grids, which are closely related to the construction of smart grids, and which involve a wide range of technologies that are relatively important, as the first of the national grid companies. 22 recommended core standards.
