Innovative research on efficient decoration methods for generator floor in underground powerhouse

Abstract

The generator floor of a pumped storage power station, as an important component of the underground powerhouse, is a crucial site for power production. During the operation of the units, significant vibrations occur, which impose higher requirements on the decoration materials and construction techniques. Compared with the traditional decoration style of the generator floor in underground powerhouses, the Qingyuan Pumped Storage Power Station underground powerhouse innovatively adopts an exposed structural column decoration form to showcase the clear concrete process and industrial factory style. It uses galvanized keels in combination with aluminum single plates, and fills rock wool color steel plates to form a composite aluminum plate to replace the traditional infill wall. Moreover, an aluminum plate installation mobile construction platform is designed and fabricated. Through SOLIDWORKS finite element simulation analysis and BIM modeling to integrate related specialties, the entire construction process is guided and dynamically controlled, effectively ensuring the quality and progress of the generator floor decoration.
