Abstract: The design and planning of the permanent plant auxiliary power system of Xiluodu Hydropower Station and the constitution and layout of the temporary power supply system in construction period were systematically introduced. According to the characteristics of the power supply system of Xiluodu Hydropower Station, the optimization scheme for mutual utilization between the permanent plant auxiliary power generation and the temporary power supply in construction period were summarized in terms of the renovation of the 110kV substation, the standby power supply of underground powerhouses at the left and right bank. The suggestions on the follow-up design and the planning of the permanent plant auxiliary power system were summed up and put forward, which affords reference for design and construction of plant auxiliary power system of other large-scale hydropower stations.
