Life Cycle Cost Analysis and Optimization of Modular Substation

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.

Analysis of the Evolution of Mathematical Models for Estimating Life Cycle of Power Substations

“…Researchers are also trying to build some life cycle cost estimation software tools used to make comparisons between AIS and GIS variants, between conventional and smart substations [39]. The LCC continues to be a main tool in the process of increasing the lifetime of power substations [36], [38], [42], [45], [46]. During this period, efforts are made to optimize the life cycle cost by employing various mathematical models, including models for evaluating uncertainty.…”
