Abstract：With an airport as an example,problems in the medium‑voltage power supply system of the airport are pointed out. The scheme for medium‑voltage power supply is gradually optimized,and one set of spare power automatic switching at the mains supply side and two sets of medium‑voltage ATS are used to solve segmented measurement by the measuring cabinet and inverse feeding by the diesel generator(hereinafter referred to as the“generator”),in order to improve the power supply reliability of the whole airport.

Key words：airport;power supply reliability;multiple power supply switching;inverse feeding;spare power automatic switching;scheme comparison;medium‑voltage ATS;generator power supply

摘　要：以某机场为例，指出机场中压供电系统存在的问题，通过逐步优化中压供电方案，采用一套市电侧的备自投及两套中压ATS解决计量柜分段计量和柴油发电机（以下简称“油机”）电源倒送电的问题，提高了整个机场的供电可靠性。
