Abstract：Research purposes:The energy utilization ratio of triple power supply system can be up to 75% -90%, because it is avialble for the system to transfor the energy closedly to the load. However, it is very important to choose the capacity of electric generating set and themode of power interconnection for the system. This paper researches the capability of electric generating set and power interconnection of triple power supply system for Beijing South Railway Station.
Research conclusions:For the currentBeijing SouthRailway Station, it is decided to install two 1 800 kW gas turbine generators after calculation of the electric generating set capacity, and for improving the working efficiency of the generator and saving investmen,t the outputvoltage of the generator is 0.4 kV, after transforming to 10 kV, interconnecting with 2 bus bars to two substations for themain building ofstation and railway freezing room separately. 2 generarors can work independly, so they can be as standby one each other if any of them fails.
