"Now, new construction of substations to choose from the six kinds of construction plans, infrastructure projects embarked on the 'integration, standardization' of the road." August 22, Guangzhou Power Supply Bureau officially released six kinds of substations typical design and construction plans, the Bureau Feng Qingliu, director of the infrastructure department, said the construction plans set a new standard for the construction of substations in Guangzhou. According to reports, the release of the six kinds of substations typical design and construction plans include three kinds of 220 kV and three kinds of 110 kV substations. 220 kV part of the whole overhead substations, all-cable substation, all-cable high-limit substation; part of the 110-kilovolt indoor transformer substations, miniaturization of substations, high substations. "The release of the construction plan is of great significance, marking a new level of infrastructure management in Guangzhou Power Supply Bureau," said Gan Lin, director of Guangzhou Power Supply Bureau. Formation of a unified construction standards In March this year, China Southern Power Grid Corporation officially promulgated the standard design and the typical cost V1.0 version, forming a unified network construction standards. The new version of the typical design uses the concept of modular and hierarchical drawing drawings to build a new framework of four levels G1 to G4 to adapt to different stages of the project to participate in the construction of different needs of all parties. "However, in the process of implementation, different design, construction and acceptance units have different finished products and technical requirements. It is like a disorganized Rubik's Cube with colorful appearances and varied finished products. The quality is uneven and the construction standards are not uniform." Feng Qing Liao said that for a long time, power grid infrastructure projects are prone to three "inconsistencies" - inconsistent design finished products, inconsistent construction finished products and inconsistent acceptance requirements. In order to realize the objective of transferring "standard compliance, green reliability, complete documentation and zero defect" infrastructure projects to the operating units and to carry out and standardize the work in depth, the Guangzhou Power Supply Bureau has formulated the V1.0 modules according to the standards of China Southern Power Grid Co., Of the six kinds of substation construction drawings, a complete substation construction drawings as a carrier, the views of all parties and technological achievements integration, the formation of a unified construction standards. Design depth to the depth of construction drawings In preparation, Guangzhou Power Supply Bureau, based on its own actual situation, optimized the standard design of G1, G2, G3 and G4 of China Southern Power Grid Corporation to form a typical design suitable for its own planning and operation requirements. For example, in the G1 layer, in order to meet the planning requirements in Guangzhou, a new 220 kV substation module is added and included in the standard design V1.0 of China Southern Power Grid Company. At the G2 floor, the council fully considers the actual needs of the operating units and makes the design more user-friendly. Su Wei, president of Guangzhou Electric Power Design Institute, said: "The stations change and the earthing can be independently arranged to prevent the spread of fire to other equipment. Expanding the area of ​​the main control room effectively increases the screen of the main control room and provides the conditions for future digital transformation Optimize the structure of beam and column cross section, reduce the width and width of the fat column, increase the interior space, is conducive to the installation of electrical equipment and integrated pipeline layout.
