Numerical Simulation of Ventilation for Main Transformer Room of Indoor Substations

ABSTRACT

Main Transformer Room of an indoor substation in Nanchang City was studied. By designing schemes with different air inlet and outlet positions, six ventilation schemes were proposed. Fluent software was used to establish reasonable mathematical and physical models for the six ventilation schemes of this main transformer room, and CFD numerical simulation was performed. According to the numerical simulation results, the indoor air distributions for the different schemes were compared by analyzing the velocity and temperature fields. The advantages and disadvantages of the various schemes were analyzed, and good schemes for air distribution for ventilation were obtained. The simulation results are of guiding significance to practical engineering and can provide a reference for the design of ventilation schemes of indoor transformer rooms.
