《3C Green Power Grid Construction Evaluation Standard》 Application Investigation and Analysis: Green Substation

Abstract

[Introduction] Through the investigation of the implementation of the "3C Green Power Grid Construction Evaluation Standard" index, the applicability of the index is analyzed, and some suggestions for the revision and perfection of the evaluation index are provided. [Method] Since "3C Green Power Grid Construction Evaluation Standard" was published in 2013, it has effectively guided the construction of many substations, lines and distribution networks of China Southern Power Grid. The investigation included 52 substations in many places, for example, Guangdong, Guangxi, Yunnan, Guizhou, and Hainan province. There were 15 three-level substations, 15 two-level substations, 17 one-level substations, and 5 small extension project. Among them, 3-star projects 15, 2-star projects 15, one-star projects 17, 5 small expansion projects. [Result] The standard plays a positive role in guiding the construction of green power grid. After the completion of the evaluation project, the proposed green grade can be basically realized, which proves that most of the indexes can be implemented. Certainly, there are some problems, for instance, the guidance of indexes needs to be enhanced, and some indexes limits need to be adjusted. The application investigation of green power grid provides a good reference for the revision of the standard. [Conclusion] The next step of standard revision should be carried out from the direction of improving the guidance of the index and combining the technical development with the revision of the limit value of the index.
