Abstract

AbstractThe flow process of underground water drainage pipeline is of great significance to the flood prevention and drainage of substation, and to ensure the demand of power supply. In this paper, the control test and numerical simulation of the flow process of underground drainage pipeline in substation are carried out. Based on the basic equations of water volume (continuity) and momentum of the full flow in pipelines, combined with the Preissmann slit assumption, the governing equations and their discrete forms of one-dimensional full flow are derived, and a one-dimensional full flow model is established. On this basis, the control experiment is carried out by using the flow process of drainage pipe, and the model is verified by the measured results. The results show that the one-dimensional full-flow model based on Preissmann slit hypothesis can effectively simulate the flow process of underground drainage pipes in substations, and provide technical support for flood prevention and waterlogging early warning of substations in humid areas.
