Abstract：The Dalüema Pump Station reconstruction project is equipped with four vertical axial-flow pumps,each is driven by a 160 kW motor,resulting in a total installed capacity of 640 kW.The maximum operational condition involves all four pump units running simultaneously.Based on the station's load requirements,a 1,000 kVA main transformer was installed.Considering the power supply needs,investment costs,and construction duration of the Dalüema Pump Station,five substation layout schemes were comparatively analyzed,and a relatively optimal solution—the box-type substation layout—was proposed.This scheme not only enhanced the overall layout of the pump station but also ensured the safety,stability,reliability,periodicity,environmental friendliness,and economic efficiency of the power supply system.The comparison and selection of different schemes provide valuable references for the field of power distribution in water conservancy projects.
