2×75kW电源车的设计与开发

The design and development of 2 ×75kW electric power-supply vehicle

2×75kW电源车是某系统地面设备的供电电源。一套系统包括两辆电源车共有4台75kW发电机组,总容量达300kW。主要功能是向6台车的发控和随动系统进行“本控”或“遥控”系统提供三相50Hz、400V交流电能;向变频车提供三相50Hz、400V、功率因数为0.8(滞后)、总功率不大于135kW的工频电能;要求两辆电源配电车的4台发电机组或任意3台发电机组均能一起并联运行,全功率输出,采用全自动并联运行装置。目前,提供的电源车均为单机供电设备,没有进行多机并联向多种地面设备供电先例。此方案是地面电源设备的发展趋势。

2 ×75kW power station vehicle is belonged to power supply of ground equipment for a system. A system combines two electric power-supply vehicle,which is equipped with 75kW four generating set,total output SOOkW. Main function has three phase,50Hz,400V AC power for control system and follow-up system of six electric power-supply vehicle,and carrys out 'control' and 'remote control',also has three phase, 50Hz 400V, 0.8 power factor(lagging) industrial frequency power supply,total output no more 135kW for variable-frequency vehicle.
