The invention discloses an electric control system for a container field bridge. The electric control system comprises a rectifier, a first inverter, a second inverter, a third inverter, a fourth inverter, a first cart motor, a lifting motor, a second cart motor, a first trolley motor and a second trolley motor, the direct-current link capacitor in the container yard bridge electric control system is a thin-film capacitor and is used for overvoltage absorption, and the stability of the system is improved; the low-inductance laminated bus is adopted, so that the overvoltage of the IGBT is reduced, and the service life of the IGBT is prolonged; a touch screen human-computer interface is adopted, the protection is complete, the functions of fault wave recording and the like are achieved, operation is convenient, fault information is stored for a long time, the response speed is high, fault directivity is clearer, and man-machine conversation is achieved; fixed-frequency direct power control based on direct power control and SVPWM modulation is adopted, the system has excellent dynamic response performance, a brake resistor does not need to be input when the field bridge operates in a commercial power supply mode, and the operation efficiency of the system is greatly improved.

    本发明公开了一种集装箱场桥电控系统,包括整流器、第一逆变器、第二逆变器、第三逆变器、第四逆变器、第一大车电机、起升电机、第二大车电机、第一小车电机和第二小车电机;本发明集装箱场桥电控系统中直流环节电容为薄膜电容器,用于过压吸收,提升系统稳定性;采用低感叠层母线,降低IGBT过压,提高IGBT使用寿命;采用触摸屏人机界面,保护齐全、有故障录波等功能,操作方便、故障信息长时保存,响应速度快、故障指向性更清晰,实现人机对话;采用基于直接功率控制与SVPWM调制的定频直接功率控制,系统具备优异动态响应性能,场桥运行在市电供电时,无需投入制动电阻,大幅提升了系统的运行效率。
