ClicksThe Standing Committee meeting of the Political Bureau of the CPC Central Committee held on March 4 emphasized the acceleration of the construction of new infrastructure such as 5G networks and data centers. In terms of UHV construction, the highlight of the "new infrastructure", the State Grid Corporation of China has invested 181.1 billion yuan in construction projects throughout the year, which can drive social investment of 360 billion yuan, with an overall scale of 541.1 billion yuan, and continue to release momentum in the overall economic and social operation. In accordance with the decisions and deployment of the Party Central Committee and the State Council, State Grid Corporation of China, while continuing to do its utmost to prevent and control the epidemic, resume work in a scientific and orderly manner and at full capacity. On April 2, the State Grid Corporation of China held the first meeting of the "New Infrastructure" Work Leading Group, and proposed to comprehensively accelerate the construction of "new infrastructure" key projects, drive the development of the entire social industrial chain, take up a big responsibility, show new achievements, and seize New opportunities, new breakthroughs, and promotion of economic and social development and industrial quality and revitalization.
Before March 5, the State Grid Corporation's UHV project has fully resumed work. What effect does the start and resumption of UHV projects have to boost confidence and stabilize expectations? How will it drive the development of upstream and downstream industrial chains and related industries? What significance does it have to improve the power supply guarantee capacity of the people's livelihood and help fight poverty? Our reporter interviewed Zhong Zhiyi, deputy director of the UHV Construction Department of State Grid Corporation of China, on these issues. "State Grid": After the outbreak of the new crown pneumonia, the construction of the State Grid Corporation's UHV project has been affected. During this period, what measures has the State Grid Corporation taken? Zhongzhiyi: Scientific research, engineering design and main equipment manufacturing are the keys to controlling the quality and progress of UHV projects.
After the Lunar New Year this year, the company immediately started scientific research and design research using remote office, video conferencing and other forms, strongly promoted the resumption of work of the main equipment factory, and strived to minimize the impact of the epidemic on UHV projects. At present, all UHV project sites have resumed work in time, UHV key "jamming" technology, and technical breakthroughs in improving DC large-scale transmission of new energy capabilities have been fully launched; all 115 UHV main equipment and key material suppliers have fully resumed production Lays a solid foundation for the high-quality completion of the year-round large-scale construction and innovative development to make up for shortcomings. "State Grid": The State Grid Corporation of China mentioned in its 12 measures to respond to the impact of the epidemic to resume construction and promote the resumption of production and production of enterprises, and actively promote the construction of key projects under construction. What is the current situation of resumption of UHV projects? Zhong Zhiyi: In accordance with the "one improvement, six enhancement" requirements put forward by the company's party group, the company has made every effort to fight the epidemic and actively promote the resumption of projects. On February 11, the Gansu section of the Qinghai-Henan ±800 kV UHV DC transmission project took the lead in resuming work, firing the "first shot" of the UHV project. At present, Qinghai-Henan, Yazhong-Jiangxi UHV DC project, Zhangbei flexible DC grid test demonstration project, Zhangbei-Xiongan, Zhumadian-Nanyang, Mengxi-Jinzhong, Changzhi station power plant transmission, Dongwu station expansion special 8 continued construction projects including the high-voltage AC project have all resumed. On February 28, the northern Shaanxi-Hubei ±800 kV UHV DC project officially started.
With the gradual progress of the resumption of work and production, the Hubei section of the project started on March 30, opening the curtain of the construction of the Hubei UHV project. At the same time, the iconic "Belt and Road" project undertaken by the company, Pakistan's Murrah DC Project, was continuously constructed during the epidemic. "State Grid": The intensive resumption of UHV projects will involve a large number of human, financial and other issues. To ensure a safe and orderly resumption of work, adhere to both epidemic prevention and control and engineering construction.
What safeguards does the State Grid Corporation take? Kind of Zhiyi: UHV engineering requires high technology and difficult construction. With the intensive resumption of UHV projects, the number of people on site has reached about 35,000, distributed in more than 1,400 operating sites in 15 provinces, autonomous regions and municipalities across the country. Tens of thousands of people are spreading construction on thousands of work surfaces, and a single converter station has a concentration of 400 to 1,000 people, showing the characteristics of "large dispersion, small concentration", and there is great pressure on site epidemic prevention and construction safety. The company resolutely keeps the "three barriers" (health check, screening and job security in place), to ensure the "three in place" (material supply guarantee in place, preventive measures in place, and supervision responsibility in place), and adopt strong measures to control it with an attitude of walking on thin ice . One is to build and operate the on-site epidemic prevention system, and the key is "detailed". Develop typical epidemic prevention plans for different operation scenarios, and accurately control all personnel by shifting, grouping, zoning, and time sharing from the source of the construction organization. An internal multi-level "firewall" is set up to ensure the supply of epidemic prevention materials, and the site is fully closed to manage to avoid abnormal health of people The risk that all personnel will be affected and isolated.
The second is to encourage local governments to approve and resume work in a timely manner. The key is "proactive". In response to the pressure of a large number of returnees returning to the site and the already severe epidemic prevention work of local governments, the company proactively connects, strictly abides by the relevant requirements of local governments, implements high-standard epidemic prevention plans, and actively promotes with the strong support of local governments Resumption of work on site. The third is to strengthen the training and management of construction personnel, the key is "practical". The company moved the personnel health check and job screening to the place of departure. After arriving at the scene, the 14-day isolation observation system was rigidly implemented. On-site personnel have established health records, one person, one card, and the body temperature is measured more than twice a day under the supervision of the safety officer, and the two principle thermometers are used for simultaneous measurement. The fourth is to ensure funding needs for epidemic prevention and control.
The required funds are included in the project cost. During the epidemic prevention and control period, insurance will be purchased for all construction personnel, so that the first-line construction units and personnel will be "reasonable." "State Grid": This year marks the end of my country's comprehensive establishment of a well-off society and the "13th Five-Year Plan". UHV, as one of the seven major areas of "new infrastructure", shows the main direction of economic and social development and industrial upgrading and revitalization . The State Grid Corporation’s annual UHV construction project investment scale is 181.1 billion yuan.
What effect does this have on stabilizing social expectations and boosting development confidence? Chong Zhiyi: UHV is my country's independent research and development, the world's leading power transmission technology, is the "golden business card" of China's power industry. As the highlight of the "new infrastructure", UHV has high technology content, large investment scale, good power transmission efficiency, and long industrial chain, which is a strong driving force for upstream and downstream industries. Take the North Shaanxi-Hubei DC project as an example. The project involves hundreds of design, equipment manufacturing, construction, installation, and scientific research units, directly driving the equipment production scale of about 12 billion yuan, which can increase more than 40,000 jobs. The company implemented the spirit of the important instructions of General Secretary Jin Ping, and immediately introduced 12 measures to respond to the impact of the epidemic to restore construction and promote the resumption of production and production of enterprises. With the resumption of work on major UHV projects of nearly 100 billion yuan as the leader, it has promoted electrical equipment and applications. The resumption of work and production in the upstream and downstream industrial chains such as energy equipment and raw materials will send a positive signal to the entire industry. This has a major role in stabilizing social expectations, supporting economic and social development, and boosting development confidence. It has demonstrated the important role of the "six forces" of state-owned enterprises and the responsibility of the "heavy tool of a big country" with practical actions. "State Grid": UHV project construction has a huge boost to economic development. After it is completed and put into operation, what role will it have on clean development, help decisively overcome poverty, and build a well-off society in an all-round way? Zhongzhiyi: The basic national conditions of my country's unbalanced distribution of energy resources and consumption determine that my country's energy resources must be optimally allocated across the country. Compared with UHV, UHV transmission has large capacity, long distance, low loss, and land saving. It represents the highest level of international high voltage transmission technology. It is an advanced technology that meets the needs of my country's energy resource endowment and sustainable development of power, and has become a support. The "Four Revolutions, One Cooperation" national energy strategy is the core technical means to realize the nationwide optimization of energy resources and the transformation and upgrading of energy structure. The UHV project plays a huge role in driving national economic development. After the project is completed, on the one hand, the resource advantages of the northwest and southwest regions can be transformed into economic advantages, helping the local poverty alleviation and building a well-off society in an all-round way; on the other hand, it can transmit electric energy to load centers in East and North China to improve the economy of East and North China. Environmental quality in developed areas, to achieve local clean development and sustainable development. "State Grid": Not long ago, the State Grid UHV Department organized the State Grid DC Corporation, China Electric Power Research Institute, Beijing Electric Power Maintenance Company and other units to carry out the Zhangbei Flexible DC Grid Test Demonstration Project at Yanqing Converter Station. activity. In the construction of the project, how do the party branches play the role of a battle fortress? In terms of party building leading the high-quality development of engineering projects, what experience is worth promoting? Zhong Zhiyi: The company attaches great importance to the construction of the party organization on the project site, continues to carry out the "Party building +" activities, strengthens the leadership of party building, promotes the high-quality construction of the project, and allows the party flag to fly high on the project site. The first is to set up a temporary party branch at the project site, incorporate all party members on site into the management of the temporary party branch, carry out party member learning and education, and enhance party members’ sense of purpose. The second is to carry out party members’ identification activities, give full play to the role of the party branch’s fighting fortress and the role of party members’ vanguard, and encourage all party members to actively identify themselves in their work, stand on their positions, demonstrate value, charge forward, take responsibility, and practice with practical actions The original mission of the party members and the dedication of the project builders. The third is to carry out party branch building activities in pairs, with "party building +" activities as the link, to deepen coordination and cooperation, solve engineering problems, create a good atmosphere, and enhance team cohesion and combat effectiveness. Fourth, for key tasks that are difficult to implement and require high technical requirements, set up a party member commando team to be the vanguard and set an example, shoulder the responsibility and set the benchmark at the grassroots level to ensure high-quality completion of tasks. The fifth is to increase propaganda, do a good job of positive propaganda and guidance, spread knowledge of epidemic prevention and control, and publicize advanced models to provide a strong political guarantee for winning both epidemic prevention and control and engineering construction.
