Looking back at the history of power development in China for more than 50 years, no one can ignore the westward change. The process of modern China's power development cannot be separated from the west. In September this year, Xichang, which created several first-largest state-owned large and medium-sized enterprises in the history of China's electric power development, once again attracted the attention of the world's power transmission and transformation manufacturing peers – China's first 750 kV ultra-high voltage transmission The electric line, the Guanting of the Northwest Power Grid to the Lanzhou East 750 kV transmission and transformation demonstration project was officially put into operation.
In this “world†demonstration project that has created many of the world's “most†demonstration projects, the three highest-voltage 750 kV single-phase autotransformer power transformers independently developed and manufactured by Xichang Company are designed with international advanced level and The structure, compact and beautiful appearance of the product has been fully affirmed by relevant experts and leaders of Guodian Company, and has become a “demonstration product†in the demonstration project, which is expected to become the design model of the future million-volt transformer.
With the successful operation of the 750 kV project in the northwest, China has ended the history of power transmission and transformation networks with no voltage level above 500 kV. Xichang Company has fully proved the Chinese loser with the independent innovation of “Made in China†750 kV transformer. Substation equipment manufacturing technology has entered the international advanced ranks. There is a song that sings well with the sword, "How can I see the rainbow without going through the storm?" It not only describes the hard journey of life, but also confirms the glory of the creation of the company.
In the first half of 2002, the Xichang Company, which has been in the top three in the industry, suffered losses of more than 10 million yuan. The fact that the production and operation suffered a major decline made the anxiety and impetuous mood of the staff of the West Transformers more and more concentrated. In the face of difficulties, Xichang Company held the first second-generation staff meeting on July 30 of this year, and just took over the new leadership team of Xichang Company, which was only one month ago, and comprehensively analyzed the development status of the domestic and international power industry. And prospects, as well as the difficulties and problems facing the company. After many investigations and arguments, a new development strategy for revitalizing the West has been proposed. The company's leaders focus on the future development of the transformer industry and based on the reality of the company.
The first is to innovate the enterprise management mechanism and start to establish a scientific management model that meets the requirements of the modern enterprise system;
The second is to increase investment in science and technology and focus on the development of “three high†products with “high-tech, high added value and high market shareâ€;
The third is to establish a new marketing system and strive to expand the market share of the company. The new team of Xichang Company also started from changing the style of cadres' work and caring for the staff's life, increasing the cohesiveness of the employees and mobilizing the enthusiasm of the employees, so that the company can work together to overcome the difficulties faced by the company.
It is not an easy task to do a good job of "three highs". "If you want to do something good, you must first sharpen your tools." The technological transformation of enterprise equipment is imminent. Faced with a serious shortage of funds, the leaders of Xichang Company have been reluctant to adjust their skills, resolutely adjust the "10th Five-Year" technical reform plan, use good steel in the cutting edge, and improve the effectiveness of the "10th Five-Year" technical reform project.
The company's organization planning, process and equipment management department evaluates the capabilities of key equipment and timely carries out technical transformation work aimed at improving production capacity and processing quality. Initiated eight major categories of 77 technical transformation projects, including the addition of 250 tons of iron core stacking platform, fuel tank coating production line, reactor iron chip shearing lamination self-production line and other equipment; the plant is closed and purified; new belt purification device Oil storage system; add necessary special tools, tools and instruments and meters. All these efforts have not only created good production conditions for the manufacture of 750 kV demonstration engineering products in the northwest, but also added stamina for the development of enterprises.
People often say: "The heart of the workers, the roots of the enterprise." While the new distribution mechanism is tilted toward the technical department and the marketing department, the leaders of the West Change Company also recognize that "excellent skilled workers are the souls of enterprise production." In the administrative report of the Staff Representative Conference in early 2003, it can be seen that an important task of the year was to "cultivate a team of excellent operational workers with high professional skills for enterprises." From the aspects of technical competition, job training, and reward mechanism, Xichang Company continuously cultivates and cultivates a team of skilled workers. All these efforts have injected new impetus into the development of the company and laid a good foundation for the production of high-grade transformers.
In August 2003, Guodian Northwest Company and Xidian Company signed a contract to provide three 750kV/500MVA single-phase autotransformer power transformers for the Lanzhou East Substation of the 750 kV demonstration project of the Northwest Power Grid. The development of the highest voltage grade products in China, with science and technology innovation to promote the all-round development of enterprises, the West changed people to seize the rare opportunities, but also faced more severe challenges!
Thousands of hammers
Although the 750 kV transmission line has been built in Canada, the former Soviet Union and the United States as early as the end of the 1960s, the 750 kV demonstration project in the northwest is the UHV transmission and transformation project currently located in the highest altitude region in the world. The ultra-high voltage power transmission and transformation project with the worst operating environment requires that its insulation level is equivalent to the level of millions of volts of UHV insulation in the plain area.
These experiences and technologies that are not mature internationally can be used for reference. The 750 kV product was completed in foreign countries from development to operation for more than ten years, while the Northwest 750 kV demonstration project was officially approved by the State Council Office on February 19, 2003, and signed a transformer with Xidian in August 2003. The supply contract was officially put into operation in September this year, leaving the development time of Xichang Company less than two years.
“Opportunity always favors those who are prepared.†When the national 750 kV grid construction is still in the “probable†and “imminent†stages, Xichang Company began to organize the technical backbone of design, process and testing to set up a research team. The goal is to tackle the key technologies of the international advanced level, and carry out a large number of technical design and review and demonstration. These research work have laid a solid foundation for the final sizing and completion of the design of the 750 kV demonstration project, as well as the formulation of the process plan and the determination of the test plan.
Adhering to the application of new technologies to develop high-voltage grade product technology routes, Xichang Company has achieved unprecedented technical cooperation in the design process of 750 kV products. Xichang Company has adopted a new, mature and reliable international advanced technology to transplant a number of world-class technologies and manufacturing processes applied to the Three Gorges DC project, the converter transformer, to a 750 kV power transformer. The designer has done a detailed quantitative analysis and calculation of each advanced technology, leaving enough margin to ensure the performance and reliability of the product. The 750 kV product fully integrates the technical advantages of the special transformer of Xichang Company, and realizes the effective combination of special transformer and power transformer.
In the manufacturing process, the 750 kV engineering construction headquarters, which is composed of the leadership team of Xichang Company, is carefully deployed from the aspects of organization, staffing, and resource integration. From the aspects of production organization, quality assurance, material supply, technical services, test acceptance, installation and commissioning, the 750 kV product special protection plan was introduced. At the same time, it has increased the assessment of various production workshops, specifically listed quality awards, awarded heavy prizes for excellent manufacturing, and improved the enthusiasm of employees; hired senior technicians to train production workers on theoretical and practical skills, and improve employees. The technical level; the daily inspection of the process of prone to quality accidents, to eliminate the quality hazards.
The technical staff of the technical department inspected the workshop every day and worked with the manufacturing workers to solve the new problems encountered in the production process. The application of a large number of new technologies and new processes in the production process has greatly increased the operational difficulty and strength of the production workers. In order to ensure the production progress and manufacturing quality of the 750 kV products, the front-line workers have paid more effort. Sprinkle more sweat.
"Quality is the lifeline of the enterprise". This is a familiar phrase. The company has not only said it on the paper, but also on the paper, and it has been implemented in concrete actions. In the production process, all key control projects of 750 kV products must be signed by the operator, inspector and quality supervision team. Each key component must be approved by quality supervision experts before being transferred.
The quality supervision team also prepares a quality supervision inspection report every day, communicates with the responsible department or operator about the existing quality problems, and puts out corrective measures or preventive measures, which are properly solved by professionals. The effect of each rectification is passed again by quality inspection. authenticating. As the checker of the final product quality of the product, the test center independently carried out the research work of the test technology without the mature test technology in the country, compiled the test program, completed the technical transformation of the test equipment, and successfully completed all the tests. And experimental analysis work.
Xichang Company takes strict quality control and quality supervision with ISO9001 quality system standards, so that each production link and every production detail are placed in strict quality control, ensuring a high level of manufacturing team and strict High-quality production of high-end products in accordance with design and process requirements. The high technical level and rigorous work style of the staff of the West has won the unanimous praise of the Northwest Electric Power Test Institute and the Italian CESI company supervision experts.
Cultivate the future
Recently, the "Proposal of the Central Committee of the Communist Party of China on Formulating the Eleventh Five-Year Plan for National Economic and Social Development" clearly states: "Equipment manufacturing industry must rely on key construction projects, adhere to the combination of independent innovation and technology introduction, and strengthen policies. Support, improve the level of localization of major technical equipment, especially in areas such as efficient clean power generation and power transmission and transformation..." In the development of 750 kV products, Xichang Company pursues the goal of “international first classâ€. The concept of “independent innovationâ€, although the company has taken on too many risks and experienced many bumps and setbacks, it won the victory and laid a good foundation for the future development of the company.
Xichang Company took the opportunity of developing the “demonstration product†of the demonstration project of 750 kV, and comprehensively improved the overall strength of Xichang Company. From 2002 to 2004, the total industrial output value of Xichang Company was 78600. Ten thousand yuan rose to 1228.4 million yuan, and the output increased from 19 million kVA to 30.74 million kVA. From January to September this year, Xichang Company achieved a total industrial output value of 1,45,513 million yuan, completing 108.7% of the annual plan, an increase of 35.1% over the same period of last year, achieving a historic leap. In the first half of this year, the output value of new products of Xichang Company reached 37%, an increase of 48% over the same period of last year, which greatly exceeded the average level of the same industry.
The 750 kV product has been a practical battle for the West Transformer Company in the field of UHV. It has trained and trained a high-level scientific research, manufacturing and management team for Xichang Company, which will save the company's sustainable development in the future. the power of.
Recently, Xichang Company won the production contract of six 800 kV UHV shunt reactors in the construction of the Laxiwa Hydropower Station built by China Power Investment Corporation. This is the current reactor with the highest voltage rating and the largest capacity in China, and will once again test the overall strength of Xichang Company in the UHV field of equipment manufacturing.
The construction of 750 kV power grid is the only way for China's power grid to achieve a span of 500 kV to 1000 kV. It has been built and put into operation to build a 1000 kV national grid main network and accumulated valuable technical reserves for China's UHV power grid. Development has a huge boost.
According to the plan of the State Grid Corporation, China will vigorously develop the UHV grid, and the UHV test demonstration project - Jindongnan ~ Nanyang ~ Jingmen UHV project construction is expected to start within the year. By 2020, China's UHV power grid will be basically completed, and the transmission of electricity will reach 200 million kilowatts or more, accounting for 25% of the total installed capacity of the country. In the next 15 years, it is the key period for China's power grid construction and technology development to seize the world's highlands. It is the key period for the State Grid to form a million-volt AC UHV backbone network. It is the key period for Xichang Company to become a top-ranking enterprise. .
With the continuous growth of the national economy, the increasing demand for domestic electricity, and the beautiful blueprint for the development of the country during the 11th Five-Year Plan, these have brought a rare opportunity for development. At the same time, the rising prices of raw materials and the fierce competition from domestic and foreign counterparts have also made Xichang Company face great challenges.
From 330 kV to 500 kV to 750 kV, in the field of power transmission and transformation manufacturing, Xichang Company has created one after another to make "China made" proud. "Xiongguan Man Road is really like iron, but now it is a step forward." For Xichang Company, every glory is a monument, and it is also the starting point of a new journey.
"Manufacturing, especially equipment manufacturing, is the backbone of the national economy." Faced with historical responsibility, Xichang Company is duty-bound. The construction of the National Grid's million-volt will set up a stage for the West to transform people's talents. This is an opportunity and a challenge. With independent innovation, the company has a long way to go.
At the mobilization of the UHV transmission and transformation project and the 750 kV project summary commendation meeting held by China Xidian Group, the first of the top 100 electric manufacturing companies in China, Xichang Company collectively and personally included the highest award of the commendation meeting. It not only marks the outstanding role of the three 750 kV transformer products with independent intellectual property rights in the whole project, but also marks another comprehensive improvement of the scientific research, management and manufacturing strength of the company.
