Research on Key Technology and Technical and Economic Indicators of 220kV Prefabricated Cabin Substation

Abstract

The prefabricated cabin substation is a new type of intelligent substation integrating environmental protection, energy saving, high efficiency and economy. In view of the characteristics of the prefabricated cabin intelligent substation, its differences with conventional substations in terms of modularity and intelligent design are compared, the advantages of the prefabricated cabin substation are summarized, the key technology research of the cabin design is carried out, and its technical and economic indicators are analyzed. The research results show that, compared with conventional standardized substations, the use of prefabricated cabin substation mode can effectively improve the space utilization rate and the flexibility of station construction, the construction area can be reduced by 19%, the construction period is shortened by about 30%, and the cost is reduced by 5.35%, which has good economic and practical value.
