Abstract
Due to the lack of high standardization and specialization, the production scale of modular substation is difficult to meet the established requirements. Compared with traditional substation construction, there are still practical problems such as high production costs. Therefore, it is still difficult to promote modular substation. Considering the life cycle of modular substation project, Cost Breakdown Structure (CBS) and Engineering Breakdown Structure (EBS) of the modular substation were defined through literature reading and data analysis. Then use the life cycle cost mapping model to further determine the mapping relationship between CBS and EBS. Finally, the connotation and goal of the life cycle cost optimization of modular substation were proposed, which can effectively promote the cost management of modular substation projects and optimization.
Highlights
With the rapid development of China's economy and the improvement of people's living standards, the demand for power grid construction is increasing rapidly
Traditional substation construction projects still face many problems, such as the difficulty of land acquisition, long project cycle, large maintenance and repair work, and the complicated substation facilities that cannot be well integrated into the surrounding environment of the city
The analysis and optimization of modular substation project costs have increasingly become the focus of research
Summary
With the rapid development of China's economy and the improvement of people's living standards, the demand for power grid construction is increasing rapidly. In order to improve the quality and efficiency of substation construction projects, substation construction is gradually developing towards modularization. The analysis and optimization of modular substation project costs have increasingly become the focus of research. In the current construction process of modular substation projects, only the cost of the construction phase is the focus, which is the main reason for the high cost of modular substation projects. If it is possible to unify the various stages of the modular substation project, optimize the project cost for the life cycle, and identify the cost components of each phase of the modular substation project life cycle, and use the appropriate method for each phase. The cost is optimized and controlled to effectively reduce the cost of modular substation projects
