| Abstract: | The evaluation of the power supply system of metro subway should, in addition to safety, reliability and economic efficiency, include quantitative indices such as trait installed capacity of main substation, average interval between rectifier substations, unit installed capacity of rectifier substation, unit installed capacity of lighting and power substation as well as some detailed quantitative indices, The paper further defines the exact specifications for a Grade-A electric load of a metro subway power supply system and power supply redistribution when the main substation breaks down, consistent with the national standards. It presents the types of emergency power sources necessary for the power supply system of metro subway and the method of estimating the capacity of power supply system . |
