Project significance
The Longdong-Shandong DC project is my country's first UHV DC project with "integrated wind, solar, thermal and storage" power transmission, and is also the 18th UHV DC project of the State Grid Corporation of China. The implementation of this project will significantly enhance China's large-scale optimal allocation of energy and power capabilities, and will be instrumental in thoroughly implementing the new national energy security strategy, meeting the power transmission needs of the large comprehensive energy base in Longdong, Gansu, and strengthening the power security system of Shandong Province. etc. are of far-reaching and significant significance.
Product advantages
This product is the first ±600 kV converter transformer of Shandong Electric Power Equipment Company to achieve all-round independent design, independent material selection, independent simulation verification, independent material procurement, and independent production and manufacturing. It is an unprecedented shortage of key raw material components at home and abroad. Against this background, the first product was tested successfully on schedule, laying a solid foundation for the scheduled delivery of 48 products in the subsequent "Three Directives and One Interconnection" project. It also once again proved the company's firm confidence in the performance of UHV high-quality production.
Performance guarantee
At the beginning of the project, Shandong Electric Power Equipment Company adhered to the results-oriented approach and fully carried forward the UHV spirit. It established a leadership group headed by the party committee secretary and chairman, and the general manager served as the general commander of contract implementation to coordinate the design, design and implementation of the project. Specific tasks such as technology, quality, procurement, production, transportation, and after-sales provide resource guarantees for project performance.
Implement the chief technical engineer project responsibility system, adhere to the three constant principles of "mature design, mature technology, and mature materials", conduct in-depth analysis and demonstration of product design, technology, manufacturing, quality inspection and other aspects, and conduct in-depth analysis and demonstration of product "electricity, magnetism, Conduct quantitative analysis and detailed calculation and comparison of physical fields such as force, heat, and flow. Comprehensively decompose and implement special measures to improve the quality of converter equipment for the State Grid's UHV DC project, strictly implement the review, inspection and closed-loop management of the technical control list, fully implement extended supervision of key raw materials and components, and fully implement the State Grid's "UHV Electrical The "Compulsory Inspection and Testing Measures for Equipment Raw Materials and Components" and the company's full inspection requirements for UHV materials ensure that every detail is strictly controlled and meets the highest standards in the industry. Through continuous technological innovation and practical exploration, independent control of key technologies has been achieved.
During the production process, all key operators in key processes are mature employees who have been engaged in UHV production and manufacturing for a long time. At the same time, the design, process, quality, and workshops jointly carry out special training and briefings for UHV operators, and sort out and formulate testimonials for key operations in the production process. At the same time, we organize joint reviews of the completion of each key process to ensure that each process meets high standards and strict requirements, ensure the high-quality completion of independent manufacturing, and win market recognition with excellent quality.
In the follow-up production process of "three direct connections and one intersection", Shandong Electric Power Equipment Company will, as always, adhere to the "four benefits" work standards and uphold the UHV spirit of "advanced planning, dare to be the first, unity and cooperation, strictness, meticulousness and truth-seeking". From the starting point, we will thoroughly implement the "20 words" work idea, strengthen contract fulfillment services, improve product quality, ensure that all products are tested successfully, put into operation successfully, and operate safely in the long term, and we will unswervingly carry the red flag and take the lead in the construction of UHV projects. Move forward, strive for first place, and work together to start a new journey of high-quality development for the group.
